Words are not sounds, and the issue is sounds and not words. I was attending a minor hi-fi show in Kent, in Southern England, and one of high-end’s odder characters, a fellow US expat named Alex Raffio, came up to me and told me to prepare myself for hearing “the greatest amplifier in the world.”. It also made as much sense out of Mahler’s Eighth as this particular ego trip full of overblown music permits. The preamp and amp match each other exactly in sound character, and the result is as intensely musical as the source material and the rest of the system permits.

In that article, he called the amp “a paradigm shift of the finest kind.”  What converted Atkinson, previously a professional bass player, was hearing deep, authentic bass utterly non-existent in systems powered by weedy little British amplifiers.

The kind of detail that never calls attention to itself unless you really listen, but adds a sense of dimension, life, and air that is impossible without it. The latest manufacturing technologies are used throughout … Recently, I was able to spend a few weeks with an as-new KSA-50 acquired by a friend. If I have any caveat about compatibility, it is that I would not use the Evolution One and Two with a warm, dull speaker with rolled-off highs.

My fellow “Saturday Morning Sad Bastard” Jim Creed found the KSA-50 for £600 ($960) on eBay, but when it arrived, we were in for a shock. If it isn’t at least very goodand very reliable over time, a product is at most worth about a three-sentence dismissal.

Another critical area was that of soundstage, which the British “didn’t believe in.”  In the early 1980s, UK reviewers thought that this was merely a US obsession with no foundation in reality, especially because a revered Linn-Naim setup was totally a “2-D” experience. Dan's oldest son, Bret D'agostino, up until the sweeping changes, was one of Krell's technical gurus. The KSA-50 was right at home, reminding me that back in the day audiophiles like Atkinson often paired Krell amps with Audio Research tube preamps. Krell announced the most revolutionary design change in its 33-year history: iBias, a patent-pending new technology that uses the Class A circuitry preferred by audiophiles yet consumes far less energy than a traditional Class A amplifier does. The company has a rich history of product introductions, each transcending mere ‘latest model year’ status by deeply impacting the high-end audio industry. Presented with a now-pristine example of the Krell, I inserted it into a system consisting of an SME turntable with a 3009 tonearm and vintage Supex cartridge, my oldest CD player (six years younger than the Krell), a circa-2010 Audio Research Ref 5 preamp, and Wilson Sophia 3 speakers. Founded in 1980, Krell has earned a distinguished reputation for engineering innovation, build integrity and product excellence. Balanced and unbalanced working is possible: around 1.5V input is required for full output; only the highest-output CD player/processors, capable of giving 3–5V, will be able to drive it directly without a line amplifier. Moreover, the problem of separating the nuances of the electronics from factors like source material, front end, speakers, and room also get to be more difficult. I did not encounter any problems in terms of interconnects when I used a variety of balanced and single-ended cables instead of CAST cables. He invested the same amount in a full restoration that he paid for the unit. It was a puzzling realization when it occurred to me that my speakers and amp cost almost as much as the rest of my system.

The Evolution One and Two were very revealing of the strengths and weaknesses of all my reference “wires,” although I should note that Kimber Select cables performed exceptionally well with both pieces of electronics.

It’s got plenty of power at 200 watts per channel and the preamp is pure Class A goodness. (I found the McIntosh MVP861 to be distinctly freer of the dynamic constraints and subliminal “noise” than the Sony SACD and other low-to-midpriced players I have heard, but I have scarcely performed a survey of the latest competitors for the state-of-the-art.).
