yeah I really think I am going to enjoy it too. I have searched and thought about it for a long time and while I looked at a lot of options out there (Odyssey, Vincent, Parasound,etc) I decided to go ahead and save a little more money and get something that would be a amp to own for a long period of time rather than just a step up toward a higher goal. The amp I bought was used so it was not the $5,500 the new ones sell for but it was still more than I have paid for any amp so far. I was like a lot of you in that the Class D 440 was good with recordings that were warm sounding and not recorded bright or badly, but when I listened to anything that was recorded brighter or was not warm sounding I just could not listen to it very long and the whole time my ears screamed. I will say that I have very sensitive high frequency hearing and can hear closer to 20k than most people I have met which might explain this as well. I am really looking forward to having an am that can run class A for more watts than a lot of amps and has Nelson Passes circuitry and his name on it stating in pedigree. I know Nelson history with Threshold, designing Adcoms amps, and after selling threshold in the 90's he went on to start Pass labs and made the Aleph and then the X and XA series among others. I feel that anything Pass touches seems to have musical magic to it and I look forward to experiencing it to full affect in my system as well.
