I once thought that high power PA and studio amps by Crown for example would be an obvious way to get the big power I thought I wanted. That was 15 years ago, since then class D came along with much fanfare but left me wanting and even the vaunted B & O ICE module amps don't sound like the amps I have come to like most, which are moderate/medium power tube amps running mostly in class A.
Believe me when I came back to audio I thought I was going to be a Krell guy all the way and still think I will want to get some Pass Class A biased amps someday. However, I'll keep my tube amps anyway even while having my dalliances with SS.
