“I finally got my system back to together.  I have a 1970’s vintage system (Marantz) with two power amps that were originally supplied power via the pre amp, via a thin jug cord type cable, I didn’t believe this to be very good, so I modified the amps to receive power directly from the GigaWatt PC-3 EVO+,using good cabling. With the system powered up through the PC-3 EVO+ power conditioner & LC-2 EVO power cable I immediately noticed a difference in the clarity of the music, the tightness of the bottom end, a brightness in the top end, the sound is completely different (in a good sense).  The greatest compliment came from my Partner (Helen) who’s immediate comment was, oh, that sounds nice (she pretends not to be audiophile ). I am looking forward to playing other music through my different formats to see what my old music sounds like through the new power conditioner. Thanks’ Terry for persuading me to go down the GigaWatt path, I could not be more happier with the GigaWatt PC-3 EVO+ Power Conditioner”…… Tony

GIGAWATT PC-3 EVO+ is a technologically advanced, new generation power conditioner, designed to power and protect audio-video systems of Hi-End class. This conditioner not only effectively protects against interference and over-voltage existing in the home power grid, but also guarantees a significant improvement of the quality of sound and displayed picture of the devices connected to it.

The main differences to the PC2-EVO+:

  • Two-sided PCBs, with thicker traces of silver plated copper
  • Sendust core filters
  • Silver plated internal wiring with bigger cross-section
  • Voltage display

CONSTRUCTION

All internal elements of the conditioner were enclosed in a rigid, steel-aluminium chassis, supported on anti-vibration feet made from solid, anodised aluminium, with a layer of proprietary elastomer 3.5mm thick.

The front panel of the conditioner is made from a thick slab of aviation grade aluminium. Its surface is brushed, after precision milling, and then anodised black or silver.

The PC-3 EVO+ has six, high quality proprietary GigaWatt power sockets, with large surface contacts. The brass contacts of the sockets were subdued to the process of technical silver plating without usage of intermediate metals, like copper or nickel, which could introduce an unfavourable serial resistance and a voltage loss. The increased surface of the contacts and the thick layer of silver guarantee good contact with the plug pins. The sockets were additionally cryogenically modified and demagnetised.

In the central part of the front, there is an LED display indicating the voltage of the input current. The precise voltmeter is very resistant to distortion and measurement errors caused by upper harmonics, at the same time not generating any interference, which would impair the quality of the power filtered by the conditioner.

The voltmeter display is red as standard, but is available in green, blue or white on demand.

The conditioner is also equipped with an additional circuit signalling wrong connection to the power grid. Its action is indicated by a red LED on the back of the unit, which signals wrong polarity of the device or faulty grounding.

TECHNICAL SOLUTIONS

The conditioner PC-3 EVO+ is equipped with multistage parallel filters. Three, independent filtering branches, which supply three sections, composed of two output sockets each. Due to this solution the kind of filtering was adjusted for the load it has, different for each type of devices – digital, analog or high current devices. Autonomous passive filters allow for isolation from interference produced by the devices connected together via a shared power line.

The PC-3 EVO+ is based on a novel filtering architecture and uses new components. The main novelty are the anti-interference capacitors and the compensation batteries for the buffering circuits, which are manufactured by the company Miflex, according to GigaWatt specification.

In the PC-3 EVO+ an innovative, two-stage current distribution system is used, a proprietary design of our company. It is based on massive third generation distribution rails, made from polished slabs of oxygen-free copper OFHCC 10100 with 99.995% purity. The first stage allows for lossless and even distribution of voltage to each of the filtering branches. The second stage provides current directly to each pair of output sockets via bolted and clamped connections as well as cabling with conductors with 4 QMM cross-section made from oxygen-free copper isolated with FEP Teflon. The star connection topology and high conductance combined with the 30 QMM cross-section of each of the rails allow for a uniform and stable power distribution regardless of the load on the individual outputs of the conditioner.

Due to the improved efficiency of the filtering circuits, they were mounted using silver solder on massive PCBs having eight times the amount of copper compared to standard PCBs. The dual layer PCBs have very wide traces made from silver plated copper, with a thickness of 280 micrometers. The interference is damped by filtering blocs of RLC type, built around proprietary Audio Grade capacitors and Super-MSS (Sendust) core filters.

In the conditioner there are no traditional protective elements, like thermal or blow fuses, which throttled the free flow of the current have a negative influence on the sound. The surge protection of the conditioner is provided by the starting block, which utilises plasma spark-gaps, UltraMOV new generation varistors and an initial filter. All those elements working together with a well-made, contemporary power grid, guarantee a complex protection against surges and over-current.

To allow for the maximum impulse response, the PC-3 EVO+ is equipped with a double buffer circuit with Audio Grade compensation batteries, a proprietary design. The circuit increases the current output with non-linear loads, like power amplifiers, as well as eliminates the difference of power between the input and output of the conditioner. This allows for almost unlimited impulse capabilities, unheard of in other passive conditioners and not reachable for active conditioners. The impulse capabilities of the PC-3 EVO+ surpass even the values of clean power line without any devices connected to it.

OPTIONAL EQUIPMENT


  • DC Offset Blocker – the conditioner can be equipped with a circuit eliminating unwanted DC component of the power grid. This DC component is a very deteriorating phenomenon, which exists in almost all power grids. It results in the sinus wave of the alternating current become non-symmetrical (non-sinusoidal) and has negative impact on all devices using transformers. It causes the cores to become magnetised, what increases their noise, diminishes the efficiency of power supplies and lower sound quality as a result of those. The DC blocker allows to eliminate this phenomenon effectively, without causing any compression or any other negative influence on the sound

  • Rolling-Ball Isolation System feet – The PC-2 EVO+ can be equipped with a new kind of feet with a mechanism called Rolling-Ball Isolation System. This is an anti-vibration system comprised of two parts (external and internal) made from solid aluminium, with two runs with balls between them. The setup is to minimise the points of contact between the feet, and then the chassis of the conditioner and the rack, what in consequence translates into a significant reduction of mechanical vibration, which negatively impacts the internal elements of the conditioner, what in turn degrades its sound. Another isolation element, on which the whole construction is placed, is a proprietary elastomer, 5mm thick.
  • White LED Voltmeter display. Besides three basic display colours a white version is available at extra cost.
  • Voltmeter display off switch. It allows to switch of the display completely.
  • Power cables – higher models. The PC-3 EVO+ is equipped as standard with the power cord LC2 EVO 1.5m length w NZ plug. To maximise the potential of the conditioner we recommend the use of the power cord LC3-EVO+.
  • Output power sockets in a different standard. The PC-4 EVO+ is equipped with the G-040 Schuko power sockets used in most European countries. To protect your children, those sockets can be equipped with automatic anti-surge protection (improved protection conform with VDE 0620). Also available are versions with sockets in other standards like: NEMA 5-20R, used in North America and some Asian countries, or AS/NZS 3112 used in Australia.

All GigaWatt products are covered by an insurance policy for the connected equipment, with a total insurance value of 1000000 PLN. The insurance does not apply to the United States and Canada.

REVIEW SUMMARIES

In the opinion of specialist audio magazines the devices from GigaWatt are among the best in the world, both in terms of effectiveness and manufacturing quality, and even surpass the standards used in the branch setting new masters. This statement is confirmed by many reviews and prestigious awards given to GigaWatt products. You can find some of them below:

Audio Activity
Italy, July 2015

 

„As I had occasion to say to the Italian importer, it is unlikely that a number of components that are placed between the wall outlet and the audio devices do not impose their voice. In the case of the PC3 Evo you hear clearly a change in the sound; but it is immediatly obvious that the system becomes more quiet, so that a slight audible hum from the horns of the Davis Monitor 1, staying just ahead of the cabinet, has disappeared thanks to the PC3 Evo.

In other words, how the Gigawatt PC3 Evo changes the sound? In my system, it worked in the right direction, producing a “more human” sound, approaching it to the music as it is perceived in a theater. So, no dynamic compression (indeed, since the equipment becomes very quiet, you might hear some very weak signals that, in other occasions, are hidden by the noise), no major interventions that alter the signal, but just some minor modifications to the frequency response, which leads to lighten a bit the medium-low at the crossing with the mid, but leaves intact all what is between the deep bass and the medium-low. The top range is of excellent quality, although in its extreme part is certainly less present; while exalted a little the mid-high range, sounding as a modern concert hall, with audience around us.”

„Test it in your system, if you have the chance.”

Positive Feedback
USA March/April 2013

 

Once I returned to my system for more attentive listening I noted all the sorts of things one associates with a good power line conditioner and it didn’t matter whether I played WAV files vinyl or the silver stuff. The goodness was more or less the same regardless of source. Most obvious was an overall reduction in low-level line noise that allowed for greater insight into recordings. Music playback became bigger, more immediate and also clearer, more intelligible and focused without any negative effect on drive and momentum. Textures were more realistic. Dynamics improved too. There seemed greater range between soft and loud. Drums and percussive instruments had more bite and snap and greater sense of liveliness. The PC-3 EVO also removed a mild electronic edge that was particularly noticeable on voices and strings. It’s one of those seemingly minor things you either don’t notice or learn to tune out until it’s reduced or removed all together.

However, the real surprise was in areas that I don’t normally associate with PLCs. Bass weight and articulation was superb and might be the best I have heard yet in my system, particularly from my REL subs. It’s not so much that bass was deeper but rather it was more visceral with greater pitch definition a more realistic sense of flow. Vocal and instrumental images were denser more robust and tactile. Timbre or tone color was more intense too. Going through my rough notes, “flesh and blood” was an oft repeated phrase. Overall the musical message was clearer, more life-like and more revealing of textures and nuance.

nagroda-roku-2013-hifi-i-m.sm

Gigawatt is most probably the best recognizable Polish Hi-Fi equipment manufacturer. The products of the company are exported to 23 countries over the whole world. Innovative solutions backed with experience in power devices, as well as very thought through development of their portfolio, led to GigaWatt being named at the same level as the most renowned manufacturers of power accessories.

In the catalog special role was always played by the power strips and conditioners, and the PC-3 EVO will probably be one of the biggest hits of the Lodz based factory. When we plug it into our system we do not need to think about what has changed. The effect is immediate, and the return to another solution – even if only for comparison reasons – painful. With the LC-2 Mk2 power cable the conditioner brings the sound of the system to another level. We have an impression, as if somebody would change all of our cables for better ones.

“The priorities were put very clear: dynamics, transparency and space. The increase of the sound quality after plugging the GigaWatt into our system was clear, and in some sense indisputable. If the sound stage would get closer or further away from the listener, everyone would be able to assess this parameter through the prism of individual preference. But here the change is based on the increase of sharpness of localization of the individual sound sources and better separation of the musicians from each other. The PC-3 EVO made the background darker, and the instruments – clearer, more realistic and convincing. The GigaWatt puts us in a situation, which does not leave space for discussion. If the sound is clearer, more dynamic, full of detail and truth, then it is better.”
“Near the end of the test I decided to make a small experiment and change the conditioner for a standard power strip and computer cables. The sound collapsed in such a way, that I could not hold it out for five minutes. You tend to get accustomed to something better quickly.”

Opinion 1
“When listening into the details, the differences turned out possible to discern. All that I lost on the previous changed returned. On one hand I noticed a bettering of the reverberation aura, vividness and length of decay; on the other I had the impression of improved dynamics. I know, this sounds very serious, this is why I want to clearly underline, that the changes were subtle, not comparable to changing an amplifier. But it is worth remembering, that they appeared after changing from very bad power accessories, which would not have been used by any audiophile, who calls himself with that name.
Yet the sum of all small things usually comes together into one whole, and this whole including the GigaWatt (and its power cord) was positive. To such an extent, that there was no return to the plastic power strip. The sound with the conditioner is taken as something obvious, and the return to a bad wire results in an anemic sound. A similar result can be achieved, including in a system a sound source of lesser quality. The GigaWatt was especially beneficial to acoustic music, where the most subtle reverberations are being followed, the sound of strings or timbre of an harpsichord.”

Opinion 2
“One might find this illogical, that if something is good, when it does not change much. But this is exactly the case with the influence of a passive mains filter – it removes what it has to remove, and if it does add something from itself, then not much. Transparency is a very desired characteristic. The sound became clearer and more resolving. I was sure, the sound gained on clarity. The definition of the lower octaves bettered; in the contrabass you could hear more the strings than the resonance of the body. The PC-3 EVO improved dynamics and gave a sense of greater clarity.”

“The result clearly contradicts the common belief, that all filters, and similar devices, devour dynamics. It turns out not to be true. Extreme signal jumps are reproduced with the same speed as when the device is connected directly to mains. Additionally, with the GigaWatt the bass became deeper and clearer, maybe because the component of interference got lesser.”

“With symphonic music, the spectrum of the instruments became a bit more visible in the midrange, and the timbre and shades of the vocals – richer. At the same time some nuances were pushed out, for example the movements of the violin bow, which were almost unnoticeable before. Chamber music recordings became more transparent, the second plane details more audible; opening of the mouths of the vocalists, breaths into the microphone and similar details. Let us agree with this, this is a very good compromise, as the main function of the devices similar to the GigaWatt PC-3 EVO is a kind of protection and safe connection of expensive gear in such a way, that it’s performance gets least deteriorated. And in this case this is successful in almost one hundred percent.”

High Fidelity No. 89,
September 2011

“Also plugging in the PC-3 EVO to my system, well “supplied” in terms of power, resulted in concrete, unanimous modifications of its sound – for the money unanimously and indisputably positive ones.”
“(…) in fact listening to music with Gigawatt we do not engage in analysis of the timbre, but we look at the same musical material under a different angle, from a slightly different perspective. (…) The sound we get is closer to us, is more palpable and nicer.”
“This is audible best when we listen to Gigawatt comparing to some cheaper power strip, with a cheaper power cable – like with the mentioned Oyaide set. This is still a very good set, my second choice, when we are talking about expensive systems, but much lesser than the reference system. And compared that, we can really hear what Gigawatt proposes, and why it is worth to pay for it almost EUR 3.300.”
“The sound with it, in such comparison, seems cleaner and (yes!) more resolved. This is mostly the result of a slight exposure of the individual instruments, their “own” sound at the expense of the acoustic environment. This results in a splendidly shown, nice, dynamic piano in recordings so distant in terms of the way of recording and time as those from the discs Moon Beams The Bill Evans Trio and Songbird Eva Cassidy. The dark, warm disc of Evans sound slightly softer, in a slightly more open way, as if the instruments would be slightly embossed, slightly pushed forward. The already mentioned disc of Audiofeels (…) sounded in a very credible way, it could be heard, that this is a meeting of a few guys who met to sing (play) together, that there is a kind of tension between them.”
“The Oyaide seemed to be the bottleneck. The Gigawatt sounded in a more open and resolved way. It was also unanimously more “three-dimensional”, the shapes were shown clearer and more unequivocal. The change seemed not be big, but you listened to everything in a completely new, comfortable way.”
“The sound of the system is very vivid and “clean”. This cleanness is not clinical, what would mean in fact depriving the sound from the flesh, but it is rather showing the depth of the sound, its physicality. Were those voices, or piano or finally the contrabass, especially important on the discs of Evans and the Modern Jazz Quartet, with Gigawatt they gained depth and mass.”

“30 kilograms of weight clearly indicates, that we do not deal with a run-of-the-mill unit here. Inside we did not find any lead pellets, only technological advancement and high quality passive filters.”
“After long time of burning-in of the splinter new conditioner, we have started the listening sessions. PC-3 was used to power the whole home cinema installation, including the LCD screen. We are convinced, that the GigaWatt does its job well. When we disconnected the audio gear from it, and plugged it back to the wall sockets, we felt slight discomfort, that grew on us in time. The sound with the conditioner gained on directness and cleanness, became less nervous and more balanced. On the LCD screen we noticed more stable and fluent picture and much better sharpness and vivid colors.”

“PC-3 has a positive influence on all AV systems. It clearly betters their performance.”

If you’re after top tier hardware of the sort, please know that GigaWatt PC-3 SE EVO+ is now filed in my privy book as the best I’ve heard to date and the one to beat, simply put victorious
Dawid Grzyb

SUMMARY: After rather extensive experiments conducted since last November, the insightful, open, effortless and clean GigaWatt also upped the ante on substance, smoothness, texturing richness and joy. 
Quality components benefit from cleaned up power feed far more times than they don’t and here GigaWatt’s items swiftly step in. This audio house established by Adam Schubert in 2007 has been all about such a cleaning service since the very beginning. The man himself is considered as a top class expert on the subject, numerous rooms with his hardware inside during this May’s Munich event (MHES) proved the point rather well. Again.

REVIEW: Instead of releasing new hardware at the usual industry pace, Adam Szubert and his team years ago took the calm and steady progression route of upgrades. His first PC-3 machine was released a decade ago and this review’s item – GigaWatt PC-3 SE EVO+ – is its fourth and final version. Enjoy. 

Introduction

I have no clue how many reporters return to their old writings, but once in a while I do get back to mine. This quite habitual activity is useful from my perspective. I see a mild improvement past comparing my articles published say three years ago to content released just recently, whereas today’s words judged another three springs from now on I’ll most likely view as something decent at best and so on so forth. However, during one of those long thorough looks in the past I discovered something interesting and related to this review’s company. For years I’ve been very much into headphones, though my transition to regular stereo hardware happened quite rapidly. I remember well my first serious setup of the sort (KEF LS50, Hegel H70, QED cables and then some) and just recently I acknowledged that the GigaWatt PF-2 power strip listed in my current reference rig has been on duty ever since. This reliable trooper is the only one left from my shy stereo beginnings, everything else is long gone.The sentimental story above also paints Adam Szubert as one of the very first individuals who decided to give a newcomer – that would be me back then – a chance. Now as for the PF-2, an itch to replace it wasn’t strong for years. Truth told, up to a point power related products didn’t interest me much and  reliability plus usefulness of this particular item by GigaWatt factored in as well. Why to fix something that ain’t broken? Or was I simply too lazy to investigate further? Maybe both? I can’t tell. In any case, quality of my daily tools increased in time and accordingly so did importance of juice for them. It was a lengthy process to fully understand this. Early on the not very sexy power matter was simply something I knew I needed to address, however today it’s nothing short but crucial for me and far more interesting than it ever was.I collected enough evidence over the years to now fully responsibly say that power and room acoustics are of top priority on the to-do list, otherwise an individual such as myself misses way too much to conduct his work reliably. Quality components benefit from cleaned up power feed far more times than they don’t and here GigaWatt’s items swiftly step in. This local audio house established by Adam Schubert in 2007 has been all about such a cleaning service since the very beginning. The man himself is considered as a top class expert on the subject, whereas numerous rooms with his hardware inside during this May’s Munich event proved the point rather well. Again.As Adam put it, the very first idea of upgrading his basic passive PC-3 power conditioner to the SE version was born more than a decade ago. This item was second only to the man’s top of the line PC-4 box loaded with 12 outlets. However, the price gap between the two was significant and no room to maneuver as far as labeling went didn’t make things any easier. Due to obvious positioning related reasons, Adam couldn’t go neither with a digit beyond his flagship nor below today’s hero. He had to act in the gray area in-between and did so via implementing tricks from the former into the latter. The process of downscaling and upping Mr Szubert’s own game was stretched in years. The ‘EVO+’ indicates the third incarnation of his PC-3 machine released waaay back, whereas the ‘Special Edition’ aka ‘SE’ bit finally closes this interesting item’s chapter. Let’s see what Mr GigaWatt came up with.

Build

The product arrived inside of a double cardboard. Dressed in protective fabric and put in-between two foam forms, it was perfectly secure. Two small boxes found underneath held a brief manual, a pair of protective gloves and GigaWatt’s LC-3 EVO power cord. Both its ends were covered via plastic caps, whereas velcro-straps surely helped in having it nicely coiled. Packaging of today’s product is the industry standard and as such is nothing to gush over. However, as it was the case with the PC-2 EVO+ power line conditioner reviewed here, its pricier sibling also shows the GigaWatt team’s attention to small things; each additional item in its own translucent bag, branded duct tape, everything uniform etc. They’re no amateurs and it shows.Just as GigaWatt PC-2 EVO+, its costlier kin does the same job; it provides protection against interference and voltage spikes present in home power grid and filters current prior to its delivery to connected hardware. Put shortly, today’s GigaWatt is here to guard and clean and as such is undeniably useful. The ‘SE’ part in its name indicates several changes found both inside and out in comparison to the standard PC-3 EVO+ model. The newcomer’s copper distribution rails of 30mm2cross-section are silver-coated (99,995%), whereas its on/off breaker is of hydraulic-magnetic type and made exclusively for Adam’s operation by Carling Technologies. The product’s chassis is also damped via bituminous-polymer composite and quality LC-2 EVO power cord included in the package is the standard option. However, GigaWatt PC-3 SE EVO+ sent to me sported even costlier LC-3 EVO model and a set of four non-standard rolling-ball anti-vibration decoupling feet. Adam’s second best also has a DC blocker circuit inside as a standard feature. The total ask for all listed luxury is €6’855.GigaWatt PC-3 SE EVO+ measures (WxDxH) 440x400x115mm, weighs healthy 16 kilograms and all in all is substantial enough to be viewed as a regular component. This item’s power consumption and total output power are 9 and 3 680W respectively, whereas max current load is 16A. Today’s star can absorb impulse current as high as 20 000A and in order to fully benefit from its protection service, a connection to an earthed socket is a must.Today’s visually is a regular GigaWatt affair, hence hardware built to last, of utmost practical sort and flamboyance level pretty much non-existent. Think Pass Labs hardware but of power related type. A thick brushed aircraft grade aluminium slab is the product’s front fixed to its enclosure via four visible hex screws strategically placed in corners. My loaner arrived silver, however a black version is also available. Nicely looking plexiglass window with manufacturer’s logo up high, model’s name down below and an input voltage LED display in-between is to be found in the middle. This feature measures said parameter in real time and its values in my room were within the 238-245V range. Red colour scheme is the standard here, however the unit sent to yours truly had white digits, but green and blue options are also available upon request. The on-site description also informs us that installed voltmeter is resilient to distortion and error introduced via high order harmonics, but all by itself it doesn’t distort or impact performance in any way. Once engaged, the handy switch on the product’s underbelly shuts voltage display and a small discrete red light takes over.The product’s rear looks almost identical to the PC-2 EVO+ model. It features six GigaWatt’s own G-040 Schuko inlets grouped in three categories. Their contacts are silver-plated, cryo-treated and demagnetized. Each pair from left to right is meant to handle digital, analog and high current hardware respectively. A nameplate next in line informs us about serial number, voltage, input inlet type, power draw, DB blocker on/off board and proud manufacturing in Poland. If engaged, the red LED located below this label indicates polarity and/or grounding issues, which I’ve found useful and convenient many times, whereas the IEC socket right next to this feature along with neighbouring main on/off switch close the list. One U-shaped steel sheet forms the item’s cover finished in matte black and with nicely engraved manufacturer’s logo on top. GigaWatt’s own decoupling pucks labeled as ‘Rolling-Ball Isolation System Anti-Vibration Feet’ are big, look reliably and undoubtedly are of quality. I have no idea who makes these for Adam, but one of well-known audio houses into such goods is my bet, highly likely local.GigaWatt PC-3 SE EVO+ might not look like a luxurious item, it’s way too utilitarian and modest to be labeled as such right from the get-go. It was made to do a very specific job, which it does truly well. However, closer inspection indicates clearly that this heavy box, just as any other similar item by GigaWatt, is finely put together and a lot of thought went into it. The devil’s in the details; all parts nicely matched, hex screws perfectly centric, components made for GigaWatt exclusively, practical set of features, utmost orderly innards etc. On visual and assembly counts today’s hero scores high in my book, not a single reason I’ve found to nitpick.At first glance, Adam’s second best deck on the inside looks very much alike the PC-2 EVO+; not only it’s as impressively made, but the general idea hasn’t changed. It’s all about even power distribution, noise suppression and protection, yet measures to reach these goals are different. Instead of regular on/off buttons loaded with traditional fuses or their thermal variants, GigaWatt PC-3 SE EVO+’s hydraulic-magnetic breaker monitors current value and stops overload spikes without these small buggers. The starter block next in line sports phase control, DC blocker circuit, pre-filter and charging module for compensation batteries. It’s based on plasma sparks, UltraMOV varistors and provides overcurrent and surge guard. The next stop are three massive rails made of silver-plated C11000 cathode copper, followed by a double buffering circuit loaded with GigaWatt’s proprietary compensation batteries made by Miflex. From there current goes to three separate sections powered in parallel. All are subject to interference suppressing RLC blocks, which incorporate quality polyester capacitors and filters based on Super-MSS (Sendust) cores. Generous bars right next to inlets and not a drop of solder anywhere in sight also don’t go unnoticed. The product’s internal wiring is teflon-insulated OFC copper and all key areas are connected mechanically via screws and clamps.And lastly, GigaWatt LC-3 EVO power cable included in today’s package recently replaced the LC-3 MK3+ leash. However, instead of being the next upgraded version as per usual, the former was made from scratch and to a degree based on GigaWatt’s tip tier LS series. The LC-3 EVO sports eight 1.5mm2 thick multi-stranded veins in total, each consists of seven tightly twisted copper conductors. This alignment decreases the product’s own inductance and leaves its fairly big capacitance intact. Used plugs are massive, their enclosures are aluminium and cryo-treated demagnetized contacts are made of rhodium-plated brass. Inner connections aren’t soldered but tightly locked via screws. The LC-3 EVO looks nice, feels pleasantly substantial and – since it’s not a solid core type – is flexible even in spite of generous thickness.

Sound

GigaWatt PC-3 SE EVO+ has been on duty in my reference setup since late November 2018. I took my time with this particular item and the list of hardware it fed since then is generous; Trilogy 995R and 915R, Kinki Studio EX-P7 and EX-M7, Accuphase P-4500 and C-2150, EggShell TanQ, Ayon Scorpio, Thöress Dual Function Preamplifier, Pass Labs XP-12, Trilogy 925 and Bakoon AMP-13R are the most important. My LampizatOr Pacific and fidata HFAS-S10U also were on the job with today’s item. But most importantly, I’ve been comparing the PC-3 SE EVO+ and PF-2 silently in case of all mentioned products and now the time has come to finally close its chapter.The PC-2 EVO+ proved to be very effective more than a year ago. Not only it very easily bested my PF-2 power strip, but also raised the bar for all upcoming GigaWatt products. The former box introduced mild expectations early on, however this report’s substantially costlier hero had it anything but easy on this count. Shortly past its arrival, the PC-3 SE EVO+ along with associated fancy cable needed to literally turn things upside down to be viewed as a at least remotely sane purchase, or so I thought. However, due to generous hardware on rotation and the reviewing process significantly stretched in time, my opinion about this particular GigaWatt shifted.If the PC-2 EVO+ swiftly dethroned my trusty PF-2, then the PC-3 SE EVO+ pretty much slaughtered it and details of how bloody this execution was I’ll politely skip. There’s no point in going this route as the newcomer and my reference box I’ve found comparable to a mild degree at best. It’s fair to say that most power components I’m familiar with tackle the same basic issues, yet the true disparity is in their effectiveness and extra touches they can apply. Figuratively speaking, the PF-2 mops dirty floor once, leaves a stain or two here and there, does nothing else and calls it a day, whereas the PC-3 SE EVO+ not only meticulously cleans the same space, but does it twice and then goes the extra mile via wax apply and then polish to leave place as pristine as it can be. Simply put, as a specialist top class sorter, the former does far more in comparison and unsurprisingly also charges accordingly.To translate the bit above into proper audio lingo, GigaWatt PC-3 SE EVO+ did everything one might expect from such an item. It rapidly and audibly removed grain from musical canvas to have all instruments and voices more visible and separated better in the process. This action in particular was its core task and several predictable upshots followed. Upstairs harshness, if there was any to begin with, was also smoothened out and less glossy yet not dimmed. At first music seemed slightly darker, however this was something I had to accommodate to. Just as quality USB cables, reclockers and the lot, power components early on might be viewed as tonal balance shifters with their guns aimed at compression and claptrap oftentimes falsely taken as extra informational content. The very first impression is almost always the same once these two culprits are removed; our ears tell us that we hear less, but what happens in reality is the exact opposite.Quality repertoire intake via high caliber hardware doesn’t have to be loud in order to hear everything. On the contrary, low level listening can provide tiniest bits of musical information. Here quality power kicks in, in this context it’s essential and that’s what the PC-3 SE EVO+ brought to the table, it extracted all musical content and showcased it in humane, palpable fashion. It didn’t soften the effect but finely stripped it from contamination and garishness, whereas dimming mentioned above morphed into instrumentally heftier and more organic act, utmost visible during quiet auditions. That’s where the true refinement of this review’s GigaWatt was found. It was pinpoint accurate yet subtle and finely moisturized at the same time; instead of shoving details in my face all at once, every image it painted pleasantly hydrated, articulate, nicely opened up and did all this without a hint of struggle. The PC-3 SE EVO+ simply made the music to flow better and many times did so potently enough to convince me that with certain top shelf companions it was mandatory.Consistency was one of the strongest cards the GigaWatt PC-3 SE EVO+ held up in its sleeve. My place in recent months was occupied via several exotic, costly and differently voiced specimens, however the Polish box did truly well in each case. Accurate and honest Accuphase P-4500/C-2150, exceptionally open and thunderous Trilogy 995R/915R, rich and impactful Thöress DFP or quick, intense and resolving Bakoon AMP-13R… it didn’t matter. Adam’s machine fed listed products skillfully enough to unlock their potential without any audible price to pay. Power conditioners are said to cripple dynamics in favour of other things they usually do, however I’m happy to report that that’s not the case with this report’s hero. All used power/integrated amps married to either the PC-3 SE EVO+ or in-wall outlet directly, sang similarly vigorously to my ears.After rather extensive experiments conducted since last November, the insightful, open, effortless and clean GigaWatt also upped the ante on substance, smoothness, texturing richness and joy. Objectively speaking, this action can be labeled as a mild prettifying procedure, a sidestep from the ultimate truth. At this point I can’t say whether musical injection of this particular sort is the PC-3 SE EVO+’s specialty, or perhaps all machines connected to it already sported such goodness in the first place, whereas my old PF-2 truncated it to effectively leave me unaware in the process. This I’ll know once another item similar to this report’s machine arrives, but that’s a story for another time. The takeaway for today is that the latest GigaWatt proved to be universally applicable, effective and not even once was viewed as not suitable for the job. On the contrary, half a year is time long enough to understand this status quo and now be vocal about it.The last thing on the to-do list was to isolate the LC-3 EVO power cord. It’s priced quite similarly to my reference LessLoss C-MARC, hence it made sense to compare the two. Both products made music to flow freely and naturally due to its edges softened up a bit, canvas for instruments darker, virtual sound sources separated better, grain nicely removed and extraction of all nuances easier in the process. The two power cords clearly had several core things in common just as quality power cords should. However, the PC-3 EVO also sounded audibly differently in comparison to my reference leash. The Lithuanian was slimmer and snappier, the GigaWatt sported boosted downstairs and packed more slam. The former displayed all events very clearly and precisely chiseled, the latter made them a bit thicker and rounder. The C-MARC was airier and finer up top, the LC-3 EVO denser and shorter in there. Again my daily driver proved me that that’s the one to go if one’s after the ultimate truth, regardless of how brutal it might be. Simply put, it did more by doing less. Still, with my feisty and informative DAC and the recently arrived Accuphase P-4500 also voiced truthfully and informatively, the GigaWatt sounded truly well. Subjectively speaking, it had my vote with these machines. I also got the impression that this cable efficiently boosted the core flavour of the PC-3 SE EVO+. The C-MARC with this power conditioner netted slimmer and less blossomed result. It was perfectly fine and very articulate as per usual, though the Polish leash went the extra mile on moisture count.

Summary

GigaWatt PC-2 EVO+ reviewed in late April 2018 not only introduced itself as a specimen way beyond reach of my trusty power strip, but it did so explicitly enough for me to understand that this oldtimer had to go. Back then I was hesitant with my decision to ditch the PF-2 most likely driven by sentiment, however now I’m not. Today’s the day.

GigaWatt PC-3 SE EVO+ and its more affordable PC-2 EVO+ sibling score equal notes on assembly quality, looks and usefulness. Both items dressed in the very same vanilla clothes are utilitarian utmost practical tools made to do a very specific job above all else, period. GigaWatt’s not into high bling factor, never was and most likely never will be. Adam and his crew have been putting function on the pedestal for years and not form. Subjectively speaking, I couldn’t care less about visuals of an item such as a power line conditioner, as long as it doesn’t poke my eyes with excessive flaunt we’re dandy. However, in 100% in-house made hardware built to last, reliably guard oftentimes very expensive companions and significantly improve upon their sonics is what floats my journo boat. That’s today’s game exactly, that’s what one pays for.

Upper four figures on GigaWatt PC-3 SE EVO+’s ask easily turn it into a costly luxurious item and quite possibly also an overkill in most cases. My sincere common sense advice is to start from lower tiered more affordable products, see what happens and move from there if financials allow it and desire to push further is still on. However, heavyweight enthusiasts far beyond entry level goods and with key components already well sorted have different needs. Many simply want to squeeze every bit of performance out of setups they already have, which leaves them with various tweaks such as today’s exceptionally potent one. If you’re after top tier hardware of the sort, please know that GigaWatt PC-3 SE EVO+ is now filed in my privy book as the best I’ve heard to date and the one to beat, simply put victorious. ‘Till next time!

Testimonials

Thanks’ Terry for persuading me to go down the GigaWatt path,

Hi Terry, 

“I finally got my system back to together.  I have a 1970’s vintage system (Marantz) with two power amps that were originally supplied power via the pre amp, via a thin jug cord type cable, I didn’t believe this to be very good, so I modified the amps to receive power directly from the GigaWatt PC-3 EVO+,using good cabling. With the system powered up through the PC-3 EVO+ power conditioner & LC-2 EVO power cable I immediately noticed a difference in the clarity of the music, the tightness of the bottom end, a brightness in the top end, the sound is completely different (in a good sense).  The greatest compliment came from my Partner (Helen) who’s immediate comment was, oh, that sounds nice (she pretends not to be audiophile ). I am looking forward to playing other music through my different formats to see what my old music sounds like through the new power conditioner. Thanks’ Terry for persuading me to go down the GigaWatt path, I could not be more happier with the GigaWatt PC-3 EVO+ Power Conditioner”
