I bought the whole evolution rig to see what Krell was up to with their new designs and I was not happy at all. The sweetness, liquidity and tonality of the gear is gone in favor of a greyish, smoothed over brittle character. Parts are now off the shelf, parts count on the amps is almost doubled and NOT Class A anymore plus they chose to impose AC filtering into the amps (no choice for the end user). Only the Evo One and Two stuff is true class A biased anymore. FPB was Krell at their best.
