Class A Hybrid - tube/fet amplifier Heros is a unique and very unusual two stage hybrid transformer loaded amplifier marrying old concepts with latest technology. The numerous benefits from using an output transformer are usually ignored mostly due to cost reasons. Yet when done correctly the result speaks for itself. 

Based on a standard cathode follower push pull output stage but modified with our design concepts and experience it features a tube input stage providing the necessary voltage amplification. Followed by transformer loaded cascoded jfet/mosfet output stage instead of the usual tube taking care of current gain much better. 

Almost double the efficiency of a normal Solid State Class A design, no DC on output and many other benefits are taken advantage of in our implementation. 

A fully differential architecture using an input phase splitting transformer and summing back at the push pull output transformer. This solution completely floats the inside of the amplifier isolating it from any external influences. 

The design being fully differential is immune to power supply noise. 

The power supply for the output stage uses a new breed of rectifier diodes made of a new material called Silicon Carbide. 

They have no reverse current and switching loses. 

When properly applied the rectifier produces no EMI/RFI in the chassis. The result is an amplifier free of grain and frizziness, giving new meaning to transparency and tone. 

We use the well known 5687WA audiophile tube. and the highest grade audio transformers 

The whole chassis is a heatsink. It is the most compact 100 watt class-A Hybrid/Solid State amplifier available. 

Operating all devices in class ‘A’ produces a reasonable amount of heat. 

The chassis is designed to cope with the heat produced by the components and provide a vibration free structure to house the components.  All the electronics are enclosed in separate compartments to stop interference between components. 

Blending this with stylish aesthetics produced a beautiful sculpture - To be known as Heros.

Thrax Audio Dionysos preamplifier and Heros monoblock test review
Matej Isak

REVIEW SUMMARY: I can relate in a same way with Thrax Heros mono blocks. With the delicate power that some tube based power amplifiers might lack, Thrax Heros acted like no solid state or tube amplifier. They actually didn't act as any other power amp I heard. They've gone beyond solid state pure A class  sweetens and bring that natural there dimensionality and sense of space from tubes. A daring and puzzling combination, but it worked far beyond of what I expected. Remarkable!
Heros are not about power but about energy in motion. Its the effortless flow of music that makes Heros so darn warm hearted. You'll get struck by the intimacy and limitless natural nuances when music is being played. Especially with live acoustical recorded music, where one can instantly find and hear the what makes amp performance so elevated. 

Thrax Dionysos received Mono and Stereo most prestige Uber amp award for preamplier that I though I'll won't gave out anytime soon if at all. Dionysos is one of the best if not the best (when implemented in a right system approach) preamplifier currently in production. Yes, quite a bold statement. With almost mind boggling internal architecture that paves the respect to the past and incorporate contemporary solutions Dionysos shifts the paradigms of what is possible when dots are connected in both researched and audible way. This preamplifier now only shows, but screams loudly how many man hours, passion and attention went not only in inner and outer design, but into an actual listening.

EXTENDED REVIEW:  Another rare ultra highlight of 2013 arrived. Rumen Artarski company Thrax captured my attention during the shows and getting to know their philosophy more deeply via their website and correspondence with Rumen. There was something so different and "right" about it that dragged my attention again and again toward their products and philosophy.

FIRST ENCOUNTER
As I often stated, everything start from the first encounter; namely the shipping boxes, packaging etc. I really love when things are done right and in the best manner. Following wooden packagin further on, everything associated with Thrax product was refined and on the level I wish most companies would present them selves and their products. In ultra high end league, this is actually a must, but mostly fail to deliver. Why exactly? Dedication, pride of own works, respect for customers

Packing, manuals components design... All over achieved! Thrax Dionysos preamplifer aesthetics are a true piece of modern industry art. I always loved statement product in a state of the art enclosures, but Rumen really went far beyond ordinary in both inner and external design. High performance electronics executed electronically and visually in trueartisan way. This is a Thrax language of experssion.

Heros monoblocks are of the same calibre. With three dimensional looks and monument aura those are one of the best looking power amplifiers if not the best I'v seen! Period! And they sing!

PHILOSOPHY
Thrax Audio philosophy and approach strongly correlates with my inner clock and how things should be made according to my understandings and feelings about ultra high-end audio. From tube rectifiers, chokes, TVC's, best materials being used, simplicity of signal, remote, quality of build etc.

Here below are just three of their reminders and wake up calls to consider, but I strongly urge you to take time and go through Thrax Audio home page for their complete views. They are not there only to entertain, but they actually educate or reminds us on quite few important points:

Transformers. Why no body does that – and why they do only a partial job.

Transformers don’t measure that well. They have limited bandwidth and rising distortion at high levels and low frequencies. All those shortcomings are true, but would seem to be substantially better performing in dynamic conditions than ANY op amp. The effect is jaw dropping not subtle.

Why do we use triodes?

Audiophiles have been led to believe through published measurements at maximum output power and uneducated reviewers that single-ended triode amplifiers produce vast amounts of harmonic distortion. As a matter of fact triode vacuum tubes are by far the most linear amplifying devices in existence today. They produce the least amount of distortion, and that distortion is predominately second harmonic, which is the least obtrusive type for the sound. By contrast, pentodes produce greater distortion, and the third harmonic tends to dominate. A transistor looks at best like a very bad pentode.

Bring theory to practice – no feedback.

It is logical that a signal passing trough and amplification stage will have some distortion added to it. (In our case this will be almost only second harmonic.) Passing trough the next stage we will add distortion to the distortion generating a minimum amount of fourth order distortion and so on. (Pretty much like the effect of feedback described above)

Consider now the following: the usual preamplifier (tube or solid state) has 3 stages (input buffer, gain stage, output buffer), then the simplest power amplifiers have 4 stages (input, phase splitter, driver, output buffer ). And all this is dependent of the signal amplitude via an extremely nonlinear function.

In order to minimizs this effect the preceding stage of any amplification stage should have at least 2-3 times lower distortion than the latter. (Would that be possible when we have 7 stages in the signal path?) Minimising the number of stages reduces drastically the order of distortion and its inter modulation products.

The sonic result is vastly improved transparency and speed.

Our products feature the minimum sensible number of stages implemented with the most linear devices possible operating in the closest to theoretically perfect operating conditions achievable.

Result? You be the judge!

INSPIRATION
All great artisans never hide their inspirations. Many of us share the respect for Japanese audio legends and their heritage. They did rewake the magic of tubes (Triodes) and approached the creational stage with their cultural norms. Those norms makes them so different and in my terms better then most other designers. It sets the artisan way. As they created a legend they followed the legends. Thrax Audio elaborate shortly:

"The works of Japanese tube gurus are a source of inspiration for us. Shishido San's designs with transmission triodes manifested trough Wavac Audio and Kondo San's creations at Audio Note Japan are the best examples of the Japanese vacuum tube art currently in production and the different approaches taken to achieve the same goal. Their attention to detail and manufacturing quality inspired us to try and do better. The works and concepts of another Japanese designer came closest to the direction in which we were heading. Never implemented commercially, however, the designs of Sakuma San are a tough example to follow. Directly heated triodes with inductive loads seemed to deliver the effortlessness and tonal richness we are after."

THE ONLY WAY
For me there are only two ways to ultra high-end heaven (with one or two exceptions, think Excalibur). Pure A class solid state or best executed tube circuits often or as a rule in A class. Outside of this territory products might sound fine and even above good, but never great in the ultimate sense. It seems that some rules of basic understanding must be followed to achieve state of the art high-end reproduction. And a talent to recognise and implement them.

It is my joy and pleasure to see and hear Thrax Audio venture going totally out of the box and above all trends to create their products in a stunning audible way. This is what  true high-end dedication means.

PURE AND PERFECT
I'm perfectionist by nature and love refined manufacturing combined with the great industry design. Both Dionysos and Heros are an example of what ultra high-end components should look and feel like. From handy remote, that reminds of Mobiado mobile phone to fine artistic details of Dionysos front plate. If you cannot appreciate meticulous CNC work and finish of this preamplifier then you must have other issues rather then respect for finest craftsmanship. I can spot the anomaly in design within seconds. It's just how my inner clocks and aesthetic sensors work. Both gift and curse at the same time as it's hard to get pleased and satisfied. Perhaps it's even peculiar. But, the thing is i can spot the un-perfection from a distance and it irritates me like anything :).

I love premium feel of things regardless of product type. Thrax products are carrying premium feeling that radiates an instant feeling of proud ownership and substantial luxury. Not in a snob like way, but with a certain aura that clearly reveals the elegancy and profound taste of man behind the company. My urge for things being done right is so rarely addressed with most high end audio products that usually feel rather mediocre in their appearance and design, then something that cost like a car or house.

Dionysos preamplifier and Heros heros monoblocks are wonderful examples of not following the crowd. Not only with their aesthetics, but as you'll find out in next lines also with what matters the most. Sound and music!

SWEET INTOXICATION OF MUSIC
I'm an indépendant and without any need to flatter anyone or follow up to advertising money to justify my writing. I can simply write through my passion and freely choose what to test and write about. Mostly I'm after the stand out products that boil my blood. Those who deliver music in its purity and potency. In that search I'm not bound to the price restriction. Both above and below. Thanks God!

Along Kondo Audio Note Japan and Robert Koda so far I simply didn't stumble upon the electronics that could ewoke such an unique musical impact as those two companies can project. Thrax joins them with big pace and it seems that even transcend at few points of Kondo unmistakable delicacy of intoxication.

Even from the first few notes being played through the Thrax Audio Dionysos preamplifier and Heros monoblock combination I was being shot directly into the vein with what Dionysos and Heros could present. A true blissful venom :). The sweet unstrained flow of music presented in a way of Monet and Degas witty view the world. Full of colour vibrancy and feeling of being there. And most importantly with the impact that last and stand continuously. A lot of high-end audio components might impress you at first glance. When you return to the listening, their initial impression fades. Through my listening notes that never happened with Thrax and I'm as excited with the music flow as I was on the first day. That should tell something right!?

With Thrax combo intimacy of sound and musciality hits you at such scale that leaves most of the gear of current high-end market light years behind. Bold statement right!?  Here are at workings something that few seems to understand or even write about. Not that I feel egocentric of special, but as I don't have to think in narrow or guided way perhaps this gives me a better position. And I'm used to high-priced high performance gear. I don't get scared or confused easily.

Thrax evoke the energy of motion. The purity of music untouched and so potent in its power to interact with listener without borders or constraints. At stake...  It's not only a matter of electronic design being used or implemented, but a subject of art and culture. The fact of the one's view of things general and particular. Choices being made and implemented.

Both Dionysos and Heros give such an impact and it feels so right. How is then that some fail to understand such products. Simple. People get scared of emotional potency and exchange! Over my twenty some years I've seen and heard quite an array of what supposed to be the best of the best. Based on numbers and some reviews those might hold some wicked titles, but at primal role of music reproduction at highest level they most fail to follow up those claims of state of the art. Ultra high-end is not a matter of background listening visionary of most. It's to be experienced directly and non altered. I know live and acoustical music by heart and play few instruments. Being in constant reset of subjectivity keeps me focused and objective. When it comes to the highest judgments I do think its a must to set a certain level of performance. Ultra high-end audio is a science by itself. It takes efforts to create those exceptional devices and it also takes mileages and efforts to understand and recognise them. Like with state of the art food, wine or horology. You cannot become an artisan or distinguish between the mediocre and the best in an easy way. It takes time and dedication on both fronts.

MUSIC
There is something special in the way that few of true state of the art products behaves. It got to do especially with inherited power of music. How it connects with us on the sublime level where things are on the emotional plane and far away from technicality being main reasoning act. It's true, that knowing music scales, history and philosophy helps in appreciating music more. Like with like an art.  It adds to experience, but not by default. It enriches you. Once you discover the historical time travel anchors of scales, movements, passions and pains behind the roots of past musical creations the primal impact is even more direct. Perhaps even poignant to a degree based on music material being listen to. But, for true emotional exchange all those variables are not needed, but they're welcomed.

We can argue a whole day long or until the cows go home about how certain audio component do or don't connect us more intimately to the core of performers and their intimate world, yet something do happen with certain audio reproduction devices. What is this exactly we fail to measure and I doubt we ever will, but we can understand a little portion to a certain degree with the overview of the technology being used. Of course when right strikes being taken. Not blindly, and in most cases not straight of the book.

Our expectations towards ultimate playback should be sky high. As prices. Sharp and direct. In the sense of ultra high end audio we're not buying into luxury segment, but a luxury performance that raises all the bars. I highly enjoy the complexity of any extraordinary design, but if it's only an outhere shell then what's the point. There are to many of such jewellery boxes out there. What I want and hanker for is an extraordinary musical box. Thrax made both wining strikes. With performance and looks. As mentioned above Dionysos looks like no other preamplifier. It's an art form of industrial design being taken seriously and above ordinary. It act as statement in physical appearance and sound performance. In a sense this is a true functional art for the music enjoyment of highest calibre. With Thrax form follow function and vice versus. Quite rare and wicked example :).

ANALOG TRUTH
Just in time I received Chad Kassem latest version of Getz/Gilberto Girl from Ipanema LP on 45rpm. Now if you need to buy one album per year here is your desert island choice. As with Acustics Sounds Analog Production of Nat King Cole Love Is A Thing analog is as great as ever. Some of the latest analog reissues or contemporary recordings like Norway's 2L digital to vinyl releases brought such a high performance to vinyl, that digital simply watch the burning smoke trail left behind by few miles. If you want to reveal a true potential of any given system then full state of the art analog front end will show the truth. Thrax combination is most enjoyable one brand system I have had pleasure to listen in my demo room. I put a lot of smilies in my listening notes and clearly noted my enjoyment of music and forgetting about the world.

I always do a reality check with the LessLoss set of product. They are my "trade standard" for testing the refinement of things. DFPC power cables quickly show the level of importance of quality cabling on any device. With Dionysos and Heroes the impact was not subtle and it only further showed the true capability of both devices. Analog is my medium of preference for reference performance and this is also where the LessLoss Firewall shows its sublime workings. Combining all this, and with an added Blackbody as Cherry on Top, the neutral performance was made clear. As written in my previous reviews of LessLoss products, they bring balance to performance and show the real potential of any given gear. With both Thrax components and LessLoss in a system they really enter the realm of state-of-the-art replay.

TRUE HEROS
As with Robert Koda Takumi K-10 Thrax Heros pulled the trick of illusion where one loose the objectivity regarding technology being used. In a blind test you cannot figure our if Takumi K-10 is a solid state or tube preamp. It holds all the attributes of tubes, but with the advantages of solid state. I can relate in a same way with Thrax Heros mono blocks. With the delicate power that some tube based power amplifiers might lack, Thrax Heros acted like no solid state or tube amplifier. They actually didn't act as any other power amp I heard. They've gone beyond solid state pure A class  sweetens and bring that natural there dimensionality and sense of space from tubes. A daring and puzzling combination, but it worked far beyond of what I expected. Remarkable!

In the upper echelon there are quite few solid state amplifiers that uses a pure class A at their heart core. Take Gryphon, Vitus etc. for example. While they performance brings certain intimacy nothing compare to the purity of Thrax Heros. They don't strain music in any way with dynamic imprint that still take away the "full magic" as with those establisehd pure Class A amps. Heros actually liberate music from solid state "cuffs".

Thrax Audio Heros looks different, perform different and act different. I can imagine only one amplifier being taken to the other shore of things beyond and that's Robert Koda Takumi K-70. I haven't listen to those monoblocks yet, but they're coming for a review in due time. 

THE DIONYSOS
Thrax Dionysos is a true ultimate component that you build your system around. You can start with it and elaborate when time and funds allow. Its performance goes ming boggling above the given price and fluidity and emotional impact makes you rethink about some of those pricey Japanese products. 

If Dionysos resembles the language of Rumen Artarski then all my respect and ego bow down to his efforts. This preamplifier is the labour of respect and love for music and all around approach with premium feeling makes one desire it even more. 

You may execute your need for branding, but there is no way to logically and emotionally pass the Thrax Dionysos when you're in the need of system change or in a hunt for state of the art preamplifier. Dionysos redefine the price structure and audiophile money being spend. Even when money not being subjet matter, you'll have the hardest task to find a competitive preamp. 

Like with IWC, Patek Philippe, Rolex etc. The feeling of handling things around Dionysos is prestigious and refine in most ergonomic way. Everything makes sense and I simply love the clear, clutter-less front plate without any prints. Anyhow. In few strikes you'll know your way around and enjoy operating it with ease.

In an Apple kind of way there are no visible screws or bolts on chassis. Design like this takes time and dedication. Result is an unmistakable aura which makes Thrax flagship preamplifier unique and stand out from the crowd. 

Thrax Dionysos received Mono and Stereo most prestige Uber amp award for preamplier that I though I'll won't gave out anytime soon if at all. 

CONCLUSION
I wrote this review in a bit different way. Above are links connected to the operational manuals and specifications for both products. With Thrax products under review I wanted to share how special and different they are. As products in league comes rarely on market, I felt a need to present them as special and unique.

If any other company would packed so much high priced modular parts and add on all the R & D of Thrax Audio Dionysos would cost a fortune and quickly jumped into the territory of sky high priced preamplifiers like Kondo M1000 etc. You can rant as much as you want with my next statement, but at given price Thrax Dionysos is an actual high-end audio bargain. If we only break down the parts cost and quality of chassis you'll will quickly gave a wake up call for most ultra-high end companies. Money have to come from Rumen Artarski other operations. I highly and openly respect this.

Thrax Dionysos is one of the best if not the best (when implemented in a right system approach) preamplifier currently in production. Yes, quite a bold statement. With almost mind boggling internal architecture that paves the respect to the past and incorporate contemporary solutions Dionysos shifts the paradigms of what is possible when dots are connected in both researched and audible way. This preamplifier now only shows, but screams loudly how many man hours, passion and attention went not only in inner and outer design, but into an actual listening.

Matej Isak

FIRST CONCLUSSIONS: Heroes possess an intricate translucent nature that reveals music for what it is. Most potent medium of profound interaction between performer and listener. Heroes, rich in tonality, zesty and radiant are capable of harmonically contoured reproduction that is both elusive, lyrically and most important sound wise reiterated at each play.  

Thrax team shows profound dexterity and they are stalwart to the Rumen Artarski strong determination regarding to how Thrax products should sound like. 

The unrestrained, enchanted music flow is most inspiring. Heroes hybrid concept brings most inspiring level of transparency, details and constitutional points of upper echelon league of the performance. For any Class A amplifier this is quite an achievement. 

EXTENDED REVIEW: I’m more then thrilled with what we could set down as a power amplifier mecca test of comparing the illuminating Thrax Audio Heros and Teres power amplifiers. As a top of the cherry the Spartacus mono blocks will join in at at a bit later date to conclude the complete the exploration of the current production of Thrax power amplifier line. 

As you can read more in depth below all new Thrax products are born as a complete different approaches to the ultra high  end reproduction of the sound. So these power amps do actually  not compete with each other, but offers a variety of choices suited to different system setups. And before you ask why Thrax is offering a such array of amplifiers the answer is very simple.  Because they can! Intriguingly inspiring…

Heroes mono blocks represent the company finer exploration of Class A Hybrid tube fet technology. They offer 100 watts of Class A via unique hybrid transformer loaded amplifier design that embrace the renowned concepts with the contemporary high tech. You won’t see output transformer in typical Class A amplifier and still you’ll find them in Heros. Its not a non working concept, but as following this route cost a money. I love the logics behind such concept and the difference is as factual as it gets. But more about this latter. 

Teres on the other hand is a transformer coupled hybrid power amplifier based on classic tube amplifier topology. Single ended tube input stage is loaded with a phase splitting transformer, which controls two separate single ended amplifiers out of phase for output. Teres implements audiophile super long life C3g input tube, silicon carbide rectifiers, shunt regulated power supply, solar cell bias of output stage, battery bias of input stage and microprocessor controlled operation. They have no feedback, uses special grade screened power transformer as well as JFET/MOSFET cascode output devices. Now if thats not enough to get you interested, then recheck of many priorities is mandatory. 

In my preview of the Thrax Audio Orpheus phono preamplifier here: link I already gave a great overview and insights of this Bulgarian High End audio manufacturer. Anyhow… To wrap it up shortly. These days you’re rarely encounter such a proficient, self sufficient and highly resolved manufacturing premises. And one needs to understand the Thrax Audio for what it really is to appreciate it on the level its deserves.

Driven by Rumen Artarski unlimited passion for highest possible musical reproduction Thrax Audio unique venture is more of the extreme, ultra high-end audio design laboratory then your typical high-end audio manufaktur. 

Few months ago at my company/factory visit I’ve had a chance to see and understand the inner workings of Thrax as company. It was an eye and mind opening experience that led me to respect it even more. 

Anyone knowing Rumen feels the similar about him. He’s one of the rare connoisseurs and high-end audio aficionados. Broadminded and culturally embossed person with and exquisite taste and knowledge that surpasses your typical expectations. 

Thrax Audio spirit for me reflect the traditional Japanese approach to the production process where the creational phase is as important as the end result. One must really see Rumen collection of rare tubes, exotic output transformers, chokes etc. to fully understand the dedication and unabridged enthusiasm. There is simply no other company doing the things the way Thrax Audio operate. This is also due the Mr. Artarski being a successful business carrier, that created an immense safe grounds for the in depth R & D of the Thrax Audio product. They can have a complete different time frame and research complexity then most of the gear out there. As a company they are not hard press from the very first moment that new product development starts. No typical taximeter ticking clock is needed. This leads to a complete different sets of the products that can operate on much very different and proficient level. 

We discussed many things with Rumen, past and present at my visit and over our corespondency. I wanted to understand his mindset and why he’s pursuing his venture the way he does. I’m no rookie when it comes to the history of high-end, basic designs, different topologies etc. But during our conversations I’ve found myself hitting the conversation stop button too often! Yes, he’s done his homework overtime and overloaded.

Seeing the literature, prototypes, schematics and amount of contemplating behind the products left a lasting impression with me. It still resonates and it’s a great reminder whenever I’m starting to contemplate about the actual meaning of high end audio. Being inspired, my reading was revived with much more complex material.

HEROS AT WORK

These days I’m not lightly inspired or awaked out of the equality of all the gear coming in and out. Thats why many times I don’t even explore further if a certain criteria is not met. Regardless of the price. 

There are so many mediocre high-end audio products eschewing the chewed circuits and designs, that its not even funny anymore. Call it a matter of globalization and greed in a simplified reasoning. A clear indication of non strange logical conclusion of why most of the sound results of amplifiers are bland and boring! Its also a matter of the goals wanted to be met. For most companies the main ruler is a quick turn over and cashing in. Whit this kind of modus operandi what can be expected as the end result? Saving on the everything and calculating to the last bit leads to employment of electronic engineers knowing little or nothing of the high-end and ultra high-end audio industry mechanics. Initial job of proper design and “voicing” in most cases actually never happens. 

There is a huge difference between designing a typical amplifier and high-end audio counterpart. Many tried to cross the bridge from the other side, but few of them succeeded. Thrax Audio employs the people with specific high-end audio skills and with decades of particular experiences. Sometime, if needed they would bring in the top most specialists, even if only for the  specific project being developed. 

And the difference between typical and ultra high-end audio potently designed power amplifier? Night and day! Not even a debate is needed when comparing the sound of such two side by side. 

This is why I’m pushing the agenda of intelligent research and making the proper homework for people are in the process of upgrading the system and changing or purchasing new high-end audio components. I do believe in common sense and intelligible nature of people willing to shelve out such a hefty amount of the money. 

DESIGN AESTHETICS

Bauhaus, art deco, with unprecedented elegant simplicity, that cuts with the contemporary aura and fails to be ostentatious like most of the high-end audio gear at any point. Elegant and timeless. Love it!

FAMILIAR LANGUAGE 

Thrax Audio Hero power amplifiers have shown their DNA and recognized sound orientation from the first few notes being played. They carry the familiar “voicing” I’m used to from the Dionysos and Orpheus. Continuity is not easily achievable. Especially with building different components one wants to open new, uncharted territories, yet without loosing the most important orientation. And for Thrax this is clearly the sound of the real music. 

There are many critical points that embarks a level of needed attributes to let any product reside on the plane of the high-end audio. What to talk about the ultra high-end, even more niche market. Thrax Heros sits both firmly and boldly on their designated throne without even blinking…

SOME MUSIC

Leonard Cohen last two albums represents some his finest music up to date. They are both very well recorded and can easily reveals whats is possible within any system. Call it simple pop or whatever you want it. To really sing these songs needs more then properly designed electronics. Same demand goes for Lokua Kanza latest album Nkolo. Pure impact of the african lyrical compositions. Simplistic yet complex at the same time. To get into the core of the songs like Elanga Yu Muinda is no easy task. Here even few of the best specced amps fall short of the vibrancy needed to encompass Lokua soulful composing. 

Grieg Unheard Reza e iRagazzi fantastic album is another album encompassing majestic execution that really needs a profound amplifier in order to come alive and Janos Starker protégée Maria Kliegel endearing playing falls even more so in line of the proficient demands and sound attributes.   

Thrax Hero mono blocks step a further into the rendition these albums and artists with an unfettered hologram like three dimensionality. They could render the music under the scope precisely and with the omnipotent dynamic barrage which can minutely shift from pianissimo to forte fortissimo without a sweat and without loosing a pace. Even most importantly the essence of music is touched and revived withe Heros. 

FIRST CONCLUSSIONS

Heroes possess an intricate translucent nature that reveals music for what it is. Most potent medium of profound interaction between performer and listener. Heroes, rich in tonality, zesty and radiant are capable of harmonically contoured reproduction that is both elusive, lyrically and most important sound wise reiterated at each play.  

Thrax team shows profound dexterity and they are stalwart to the Rumen Artarski strong determination regarding to how Thrax products should sound like. 

The unrestrained, enchanted music flow is most inspiring. Heroes hybrid concept brings most inspiring level of transparency, details and constitutional points of upper echelon league of the performance. For any Class A amplifier this is quite an achievement. 

I’ll continue when a pair of Teres mono blocks will hit the shores of Mono & Stereo HQ’s. My venture came to the point where I can be very selective in my choices of the products being reviewed and tested. In this way more focus and listening can be dedicated to the stand out equipment. Thrax Heros certainly represent a healthy new breeze of the products being more than worthy of highlighting. 

Stay tuned….
