I've owned both the Levinson 336, the new Classe CAM350 monoblocks and the Krell FPB300c. Neither of those amps are very musical sounding. The Levinson is much too dull and the bass is decent but not realistic or fun to listen to. The class was the most musical sounding but lacked the last word in detail. The Krell was by far the most detailed sounding and I think some people call it machine like because it emphasizes the treble, which is why you hear all the air around a recording. Using them I demoed their respective preamps (380s, KCT etc..) and I didnt' really like any of them. It wasn't until I tried a Audio Research Preamp that I found bliss. The point of a preamp is to add harmonics to the sound aka musicality. The point of an amp is to be able to drive a speakers and as far as that went, the Krell was by far the fastest and more powerful of the amps. I would go with a Krell FPB300 with an Audio Research or Conrad Johnson amp, somewith with somewhat euphonic sound. It'll make the combo sound very neutral. You never want to much of any one sound or it'll get boring or tiring. The Audio Research and Krell combo are hard to beat. I've also tried Goldmund and Spectral which I think are the most detailed and musical products out there. I am going to sell my setup to get Goldmund, because it has the musicality of tubes with the speed and precision of solid state. I hope this helps.
