The amplifier that pulled this trick off was the aforementioned Soulution 710, the brainchild of Cyrill Hammer, the founder of the Swiss high-end audio firm Soulution, and the late Christoph Schürmann, formerly of the German company Audiolabor and at the time working for Cyrill. It took the pair better than half a decade to perfect their circuitry, but perfect it they did. The result was astounding. As I said at the time, “with a transparent-enough speaker and source, the Soulution 710 simply isn’t audible in most of the usual ways that solid-state or tube amps are audible. It isn’t dark, and it isn’t light; it isn’t warm, and it isn’t cool; it isn’t liquid, and it isn’t dry; it isn’t fat, and it isn’t lean; it isn’t sweet, and it isn’t sour; it isn’t great at the frequency extremes but less lifelike in the midband; it isn’t flat or airless, and it isn’t bloated or overly bloomy; it isn’t terrific on starting transients and AWOL on stopping ones; it isn’t too tightly focused, and it isn’t too loosely defocused; it just isn’t. And since it isn’t, speakers (at least those capable of high levels of transparency and neutrality) aren’t, either.”
