To me buying extreme high end amps is like buying art works or high quality furniture. As far as the electronics go it is all hypes and in some cases, BS.
The fact is, with today's technological advance, audio amplifier is a mature product, relatively simple/low tech stuff. You don't need much secret know how to build amps that can faithfully amplify audio frequency signals within the 10 to 30 kHz spectrum. Even an electronic keyboard in the right hands can easily fool us in believing it is something else. Don't get me wrong, if I have some extra cash I would quickly pull the trigger on some McIntosh tube preamp and SS power amp that I have been eying for a few years, but I would not be buying them for better SQ. In fact for accurate sound quality (faithful to the input signal) I have more faith in main stay products by Marantz, Denon, NAD, HK, Arcam etc., than in some of those Carver amps or their equivalents. The thing is, I don't even care if those things sound good to me or not, I rather listen to true hifi than the twisted sound that actually sounds good. So I am on the opposite side of those who believe in who care about specs and what not as long as it sounds good. Of course that's just me, and obviously we all have our own preferences.
Sorry about sounding extreme but I am telling what I believe.
