Krell Industries Launch a NEW Integrated Amplifier the K-300i
Amplifier legend Krell Industries has announced its new K-300i Integrated amplifier which boasts newly developed amplifier circuit with Krell iBias that can deliver 150w @ 8ohms and 300w @ 4 ohms. Greaty revised IBias provides the sonic benefit of Class A operation without the excessive heat and power consumption of traditional class A designs.

"All I can say is WOW! I have never, and I repeat never, in over 30 years of professional audio sales and system design, heard a solid state product like this before. The phrase "tube like" has been bandied about for years when you have a solid state product that strives to recreate some of the magic of modern tube electronics, however, with the new K-300i, which I understand was the inspiration for the XD upgraded Duo, Chorus and Solo amplifiers series, you have actually done it! There is an organic wholeness and lack of grain to the sound which once you experience it, you know in an instant, this is not your typical solid state Hifi gear" ..... Dave Lalin, - Audio Doctor

The K-300i also boasts a 770VA Transformer and 80,000 uF capacitance for excellent signal control and dynamics.  Krell Current Mode to[topology is used with fully differential circuitry that runs from the input stage through to the last output gain stage proving and extremely linear and extended frequency response curve with smooth, effortless highs and extremely dynamic bass energy.

There are two versions available the "Classic" and the "Digital" the latter comes with a world class DAC featuring support for the latest digital music formats.  An ESS Sabre Pro DAC configured for high current output performs the digital to analogue conversion for un compromised audio reproduction.  A network streaming audio renderer with dedicated mobile App plays AAC, ALAC, AIFF, FLAC, WAV and WMA Files with DoP files supported to 192kHz/24Bit from UPnP music servers or Nas devices.
With the "Digital" option the Krell is both MQA and Roon Ready along with Spotify, Tidal, Deezer, Qobuz and vTuner Radio streaming services being supported
There are HDMI inputs and outputs supporting 4K UHD and HDR to allow audiophile grade sound quality integration into Home Cinema systems.  A single USB port is available on the front panel with other USB ports on the rear for user friendly option to stream music from any computer and there is also a Bluetooth Receiver with aptX Technology
The K-300i has an internal web server that is optimised for tablets and provides a remote graphical user interface for convenient and intuitive control.

The Promise
The new K300i-XD  competes with the very best out there that cost significantly more. The price is attributed to our decision to source main boards from US factories only, so we could sensure highest quality, reliability and performance worthy of the Krell brand, to enable us to bring Krell back to its palce at the top once again.

When developing the K-300i-XD, David Goodman, our Director of Product Development, whom has been with Krell since 1987 and was largely responsible for design work on all Krell products, discovered that with modifications to the output stage, we could vastly improve sound quality, across the board, to all of our amplifiers.

The Result

A deeper, darker, blacker background that provided significantly better macro and micro dynamics, more silence between the notes. Vocals and midrange took on an organic, yet more vibrant tone, enabling us to hear much more body, and even though our amps were great before, there was a very significant improvement. 

The speakers disappeared; yet, instruments were more focused with appropriate size and specific soundstage locations. All in all, a much better sounding, much improved experience that was easily, immediately heard by all that listened.

Renowned American amp brand, Krell Industries, has just unleashed the K-300i Integrated Amplifier .
Krell made an impact with their KAV-300i integrated amplifier in 1999. Today, they are hoping that the all-new K-300i integrated will find similarly enthusiastic fans.

The 18.2kg K-300i incorporates a newly developed amplifier circuit design featuring Krell iBias tech. This delivers 150 Watts per channel into 8 Ohms and 300 Watts per channel into 4 Ohms. Additionally, iBias provides the sonic loveliness of Class A but without the traditional accompaniment of excessive heat and power consumption. Regarding power, there is a 770VA transformer with 80,000 microfarads of capacitance. The upshot of all that is excellent signal control and dynamics. 

Furthermore, with Krell Current Mode topology employed with fully differential circuitry running from the input stage through to the last output gain stage, we are told that we can expect an “extremely linear and extended frequency response curve with smooth, effortless highs and extremely dynamic bass energy”.

Analogue connections include two pairs of balanced XLR and three pairs of RCA on the input side, whereas outputs are catered for by two pairs of speaker binding posts and a single pair of RCA to run to a preamp.
Upgrade the analogue unit with the digital option, and you get the benefit of an ESS Sabre Pro DAC and networked streaming audio renderer with a dedicated mobile application.

The K-300i’s internal web server is optimised for tablets and hands the user convenient and intuitive control. The player is compatible with the latest digital audio formats including AAC, ALAC, AIFF, FLAC, WAV and DoP files up to 192kHx/24-bit from UPnP music servers or NAS devices.

The digital option also provides Spotify, vTuner Internet Radio, Tidal, Deezer, and QoBuz streaming services. Good news it is also Roon Ready and will decode MQA.

Connectivity-wise, the digital module brings HDMI 2.0 inputs and output supporting 4K UHD with HDR for audiophile-grade TV viewing. Upfront is a USB port enabling playback from flash drives. There is another USB port around the rear so that you can stream music directly from a laptop or computer. Wireless fans also are served by aptX Bluetooth. Rounding off the digital inputs are a coax and an optical port.

When developing the K-300i-XD, David Goodman, our Director of Product Development, whom has been with Krell since 1987 and was largely responsible for design work on all Krell products, discovered that with modifications to the output stage, we could vastly improve sound quality, across the board, to all of our amplifiers.

THE RESULT

A deeper, darker, blacker background that provided significantly better macro and micro dynamics, more silence between the notes. Vocals and midrange took on an organic, yet more vibrant tone, enabling us to hear much more body, and even though our amps were great before, there was a very significant improvement. 

The speakers disappeared; yet, instruments were more focused with appropriate size and specific soundstage locations. All in all, a much better sounding, much improved experience that was easily, immediately heard by all that listened.

The technical explanation from David:

“The “XD” update to the Chorus/Duo/Solo/K300i amplifiers reduces the output impedance to less than half of its original value. This lower output impedance better damps unwanted speaker vibrational modes. Changing the output impedance also necessitated re-compensating each amplifier stage to achieve optimal critically damped transient response. This ensures that the amplifier accurately follows the dynamics of the input signal.”

This New XD update has been applied to the entire lineup of Krell amplifier. All amplifiers, aside from internal modifications, will have an “XD” silk screened on to the left front panel to denote the change.

All I can say is WOW! I have never, and I repeat never, in over 30 years of professional audio sales and system design, heard a solid state product like this before.
Dave Lalin, - Audio Doctor

SUMMARY: All I can say is WOW! I have never, and I repeat never, in over 30 years of professional audio sales and system design, heard a solid state product like this before. 
The phrase "tube like" has been bandied about for years when you have a solid state product that strives to recreate some of the magic of modern tube electronics, however, with the new K-300i, which I understand was the inspiration for the XD upgraded Duo, Chorus and Solo amplifiers series, you have actually done it!
There is an organic wholeness and lack of grain to the sound which once you experience it, you know in an instant, this is not your typical solid state Hifi gear.

I am writing this email to you while listening to our brand new demo KRELL demo K-300i Integradted amp playing Miles Davis, Herbie Hancock and Lee Morgan tracks.

All I can say is WOW! I have never, and I repeat never, in over 30 years of professional audio sales and system design, heard a solid state product like this before.

The phrase "tube like" has been bandied about for years when you have a solid state product that strives to recreate some of the magic of modern tube electronics, however, with the new K-300i, which I understand was the inspiration for the XD upgraded Duo, Chorus and Solo amplifiers series, you have actually done it!

There is an organic wholeness and lack of grain to the sound which once you experience it, you know in an instant, this is not your typical solid state Hifi gear.

The sound of the K-300i just draws you in to the experience of music. Even listening from the next room, the piano and organ have the flowing roundness of a real instrument.

Another extraordinary trait of this little amplifier, pun intended, it weighs 52lbs and feels like it was cut from a solid block of metal. There was a rim shot on the drums which made me lift my head from reading emails while sitting in my listening room. It was so life like and startling, and this is with only a short period of break in.

Combine this magical liquidity and sense of presence with a deep, well controlled bass response, a large soundstage, good top end extension, and thrilling dynamics, and add in a modern feature set with Roon and MQA capability, built in ethernet streaming, Apt X Bluetooth, HDMI in and outputs, and a ton of both analog and digital inputs, with enough power to drive real world loudspeakers, and it makes this one very special integrated amplifier. I will find it hard to recommend anything else but Krell to my clients, and we sell many of the top performing brands of electronics in all of audio.

We have not yet fired up the big guns, our new Demo Duo-300XD & Illusion-2 [reamp/DAC. I expect we will find this gear is even better than the little integrated with the XD upgrades as I’ve read in many publications over the past few months, and again we will likely find it hard to recommend our more expensive reference gear which is well over $50k. This level of sound quality is more akin to radically more expensive brands. Please get the word out that Krell is back! We are so pleased with these new products, you are going to have a bright future.

Krell is one of the foremost gems in the vein of classic American high end manufacturing, and like Harley Davidson, you are well on your way to restoring Krell back to its glory days.

I have owned many classic Krell products like the KSA 250s, a KRC HR, and 450 Mcx Mono blocks, as well as some of the finest tube gear from Conrad Johnson and VAC, so I know what good sound sounds like. The new K-300i is a quantum leap over the older classic Krell gear, and anyone who doubts that just needs to listen for 30 seconds to confirm that.  

Dave Goodman should be congratulated. Whatever he figured out with the XD series circuit advances the art of music reproduction.

Thank you for your recommendation of the K-300i and Krell in general, I can't remember the last time a product in this price point sounded so remarkable and was such a joy to use.

Please feel free to quote me on this, I stand by absolutely every word.

Sincerely,
Dave Lalin - Audio Doctor
The Krell K-300i - The Return of a Classic
Gregory Petan

SUMARY: "It’s a true treat for this long time Krell user to hear what they’ve achieved with their latest XD technology and the K-300i in particular. At this price, it can make an excellent anchor for a reasonably priced, yet high performance audio system. Its compact form factor makes it an easy roommate to live with as well. “ … "The K-300i is a piece that I suspect its owners will treasure for a long time.

 
It’s funny what you remember. My tenure with Krell goes way back, to the demo room I was scared to enter, where an early Krell KSA 150 was matched to a pair of Apogee Stage speakers. Even though I had just purchased a Rotel integrated from the same dealer the “Krell room” seemed like exalted territory.
 
The sound and appearance this combination made played heavily on my senses – even the smell of this amplifier had an aroma that neither the Classe or Levinson amplifiers possessed, and this combination that was the KSA 150 engaged on all levels. It was an audiophile elixir. I soon became obsessed with Krell and purchased a KSA 150.
 
Moving up the product range, the next generation FPB 300, FPB600, KSL preamp, SPB32-X DAC, KRC preamp, the KPS20i cd player and finally the KPS25i cd player would follow. This was money spent with consumer dollars, not reviewer dollars.
 
Throughout my journey reviewing a wide range of manufacturer’s components, I’ve always rooted for Krell’s success, though I haven’t had much experience with current products since founder Dan D’Agostino moved on to form his own company. In the middle of evaluating a number of integrated amplifiers, Krell’s Walter Schofield offered the first crack at Krell’s K-300i, making for an excellent opportunity to revisit the brand.
 
Slim and powerful
 
Despite a low-profile enclosure, the K-300i weighs in at 52 pounds. Producing 150 watts per channel into 8 ohms, doubling into 4, the K-300i provides the weighty, grip that will entice newcomers, and be familiar to fans. The 1/2-inch milled aluminum front panel (available in silver or black) completes the homage to Krell products past, while the curved front keeps an eye on the future.
 
The K-300i is loaded. Equipped with 2 HDMI inputs, 1 HDMI out and a preamp output to compliment two pairs of balanced XLR inputs and 3 RCA line level inputs, everything at your disposal will easily plug in. Those checking the digital box also have Toslink and coax inputs along with USB and RJ45 ethernet inputs, as well as Bluetooth/aptX capability. This is a well thought out product as a stand-alone control center or integrated into a full home system via the RS-232 ports.
 
Vinyl lovers will need an outboard phono stage, but with so much going on in this compact chassis, I’d almost prefer keeping the delicate analog signal out of this box, and why pay for functionality you don’t need? Digital music lovers are in luck, with Krell offering an internal, streaming DAC for an . This includes an on-board DAC and Roon Ready streamer, that will decode digital files up to 24/192 and unfold MQA as well.
 
Krell’s David Goodman, their director of product development and head of engineering is the person behind the current XD series of amplifiers. As we saw in a recent comparison, the difference between their last series of amplifiers and those with XD technology, the improvement is not subtle.
 
Goodman relates that the XD upgrade (Xtended Dynamics, Xtended Dimensionality, Xtended Detail) “takes an already great sounding amplifier, and raises its performance to the next level. This is a perfect example of Krell’s continuous R&D efforts delivering benefits across multiple product lines. During the development of the K-300i, we discovered substantial sonic improvements lowering the amplifiers output impedance below traditional norms. Applying this to the existing products made for an equally big improvement and required a unique designation, hence XD. This lower output impedance exerts more control over the speaker drivers and damps out unwanted vibrational modes, allowing a more accurate reproduction of the original signal.”
 
Exceeding expectation
 
Fully anticipating big dynamics and a tonal balance favoring the lowest octaves, as with past Krell product, the K-300i is vastly different from past Krell efforts. It’s a top to bottom improvement towards a more refined, yet more musical sound. The lower registers are more refined and controlled at the same time.
 
Retaining the dynamics and forceful low end that’s made Krell famous with audiophiles the world over, the K-300i is more nuanced and natural in its musical delivery. There is a sweetness to the sound that is reminiscent of the original KSA-50. The K-300i is non-fatiguing, inviting you to turn up the volume on your favorite tracks – right out of the box. That’s always a great sign. Remember, Krell amplifiers are still class-A, but thanks to Krell’s current i-Bias topology, they don’t run as hot, or draw as much power at low volume levels as the original models did. Yet the K-300i still draws 900 watts from the AC line at full output – and generates a fair amount of heat.
 
Utilizing a wide range of speakers from Sunny Cable, Lansche and PBN, nothing threw the Krell a curve ball it could not field. After a solid week of burn in, some direct comparisons to my reference D’Agostino Momentum Preamplifier and Pass Labs XA200.5 monoblocks, reveals the big bucks gear still having the edge, but it’s not as big as you might think. The key word here is value. This is performance that would have been unheard of ten years ago for this price.
 
Great with all sources
 
This newfound balance altered my approach. Past Krell components always had me reaching for the more bombastic selections in my music collection, but the K-300i sends me to vocal rich recordings, exploring the heart of the mid band and treble in ways that older Krell designs did not inspire as a first move. From Sarah Vaughn’s previously unreleased concert pressed by Devialet, via my VPI Avenger Reference, with the Gryphon Sonett and Boulder 508 phono stages, it’s easy to see what this amplifier does so well.
 
Liquidity, color, expressive dynamics, and space. All positive aspects of these two phono stages, and the differences between them are clearly rendered by the K-300i, revealing the emotion present in the recordings auditioned. Sarah Vaughn’s vocals sound full of life at times and a weary at others. Eva Cassidy’s Live at Blues Alley is another familiar go-to when trying to reproduce inflection, a wide range of dynamic control, and emotional impact. “Bridge Over Troubled Water” from this band is wonderful, and though I’ve heard this recording so many times, the Krell never gets in the way of the music.
 
Compared to my reference McIntosh MB50 streamer, the Krell provides a more intense presentation to the Mac’s slightly sweeter rendition. If I didn’t already have an outboard streamer, I could happily live with the one built into the Krell. For the less than the price of a decent pair of signal cables and a power cord, you can have it all inside the chassis. A great thing for those craving simplicity.
 
Just a quick note about the HDMI performance of the K-300i. In a word, it is phenomenal. Watching Mary Queen of Scots, my wife and our friend agreed, it was like we had upgraded our modest Epson projector several levels. Color saturation and detail rendition was startling as was the contrast and brightness. If you are like me and your audio system does double duty as your home theater, the upgrade in video quality alone not to mention the ease of integration is worth at least half the overall cost the K-300i.
 
Coming to grips with it all
 
On balance, this is one of the best sounding pieces of Krell gear I’ve had the pleasure to use. While the last bit of resolution and slam from their top products is not here, because you can’t have everything for only NZ$15,995, Krell has made it a point to deliver a high degree of sonic excellence and balance in this compact package. Those needing more power can consider using the K-300i as a control center and adding a more massive Krell DUO or MONO power amplifier later.
 
The only part of the K-300i that I didn’t terribly enjoy was the Bluetooth streaming, but this is not my favorite way to listen anyway. Still, it is nice of Krell to offer this, so that when friends drop by and want to share their favorite playlist, connectivity is only a click away.
 
It’s a true treat for this long time Krell user to hear what they’ve achieved with their latest XD technology and the K-300i in particular. At this price, it can make an excellent anchor for a reasonably priced, yet high performance audio system. Its compact form factor makes it an easy roommate to live with as well.
 
And I still think about that KPS25i – it was one of the coolest pieces of audio gear I’ve ever owned. It’s funny what you remember. The K-300i is a piece that I suspect its owners will treasure for a long time.
The sound with the K-300i driving the Sonus Faber Olympica III Loudspeakers was exceptionally fast and clean—more clear mountain stream than, what, furry animal babies?
Jim Austin,

Is the K-300i's sound consistent with the company's new more approachable image? Is it, as the brochure suggests, "clean, powerful, natural sound in all its subtleties, colours, and gradations"? It's impossible to judge based on a short listen in an unfamiliar room and system with unfamiliar tunes, but here's my first impression. The sound with the K-300i driving the Sonus Faber Olympica III Loudspeakers was exceptionally fast and clean—more clear mountain stream than, what, furry animal babies? I don't know these loudspeakers, but I've found the Sonus Faber house sound to favour warmth and ease over speed and ultimate resolution. Driven by the K-300i, the Olympicas didn't lack for warmth—nor were they the least bit bright or etched. But there was no dearth of articulation, from the bass on up. So, yes, waterfalls and Alpine pools, bracing, cool, clear water—those aren't bad sensory analogies.

Krell had a big display at Munich High End show and seems to be on the brink—or maybe in the midst—of a major new-product and marketing surge.

Walter Schofield, the company's COO, told me that in addition to a few new products recently introduced, many more are just on the horizon. The new products—and the new marketing push—are based on two recent technical advances. The first, iBias, which was introduced by Krell in 2014, is a sliding-bias scheme that ensures there's always a positive bias for both phases of the waveform. Sliding bias is like class-A in that a bias voltage is always maintained, eliminating crossover distortion, but instead of a large, constant bias as in class-A, the bias voltage tracks the signal, staying as small as it can be while assuring that it's bigger than the signal. In contrast to most (or all? I don't know) other sliding-bias approaches, iBias uses the amplifier's output —not its input—as its reference, so it accounts for the interaction between the amplifier and the loudspeaker.

Longtime Krell designer David Goodman told me that the resulting distortion is almost entirely of the third-harmonic variety; he insisted that third-harmonic distortion is preferable to second-order—which provides some indication of the sound Krell is aiming for.

The second advance, which the company calls XD, is a method for reducing output impedance. The key insight, which Goodman told me was discovered in the course of developing the K-300i integrated amplifier is that "lowering the output impedance below traditional norms" results in "substantial sonic improvements."

Krell's technology surge comes with a renewed marketing effort aimed at altering the brand's image. On the substance side there's a renewed emphasis on product reliability and customer support: The K-300i brochure notes the company's commitment to "ultimate reliability" and "white glove service," and the 300i comes with a minimum 5-year warranty. On the image side, there's a focus on nature and humanity. That brochure offsets images and descriptions of the product and its sound with nature photos and an endorsement of the Nature Conservancy.

The energy savings facilitated by iBias fits this environmental image—but many audiophiles will likely be more influenced by the practical advantages of the technology than the planet-saving ones. The K-300i can deliver 150W into 8 ohms and double that into 4 ohms, according to published specifications. A pure class-A amplifier capable of that much power would be big and heavy and dump a lot of heat into the listening room. The K-300i is a normal-sized component—a typical 17 1/4" wide and 18" deep and a few inches tall—and it weights a modest 52lb. It burns just 46W at idle; a 150W class-A amplifier would consume more than ten times that much power and put more than ten times as much heat into the room.

Is the K-300i's sound consistent with the company's new more approachable image? Is it, as the brochure suggests, "clean, powerful, natural sound in all its subtleties, colours, and gradations"? It's impossible to judge based on a short listen in an unfamiliar room and system with unfamiliar tunes, but here's my first impression. The sound with the K-300i driving the Sonus Faber Olympica III Loudspeakers was exceptionally fast and clean—more clear mountain stream than, what, furry animal babies? I don't know these loudspeakers, but I've found the Sonus Faber house sound to favour warmth and ease over speed and ultimate resolution. Driven by the K-300i, the Olympicas didn't lack for warmth—nor were they the least bit bright or etched. But there was no dearth of articulation, from the bass on up. So, yes, waterfalls and Alpine pools, bracing, cool, clear water—those aren't bad sensory analogies. As for the subtleties, colours, and gradations, judgment on that will need to await a longer, more focused listen.

A streaming DAC module is available, the DAC supports Roon, Tidal, Qobuz, Spotify, and MQA. The K-300i's warranty is 5 years from the purchase date, or six years from the time it was sent out from the factory, whichever is longer.
