As it turns out, I've had the chance to compare Classe 401, ML 336, and Krell FPB300 in the last two months. If you're looking for the smooth midrange, ML is the one. Classe didn't seem to have the imaging depth (I've found this to be true for all Classe stuff when compared to higher-grade amps). I have to disagree with Lev335 regarding the slam factor though. While the ML had reasonable slam, it was simply not the equal of the Krell in that department. By comparison, I found the ML "soft-sounding" even though it had more power (350@8 vs. 300) and a true dual-mono architecture. I would also say in general that the Krell's "lack of refinement" is overstated. Not quite as refined as the ML in the mids and highs, but to suggest it has none at all is simply not true. Good luck!
