    Are you aware they share the same father? Pass was paid to create a number of Adcom schematics. They were built to a different price point.

    I'm sure you'll enjoy it. I still use its progenitor from 32 years ago, the Threshold Stasis 3...

    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.

    Congratulations on your Pass Labs amp. You should be happy with it for a long time. I have never missed my class d integrated amp and I doubt you will either.

    I will post pictures once I get it hooked up. I don't think I will miss the Class D amp either, I just don't think that the Class D audio amp was the kind of sound that I like and works in my system. I am not saying that they are bad amps at all and the proof is in the people just on this site that uses them with some very revealing and hard to drive speakers. But I think with the Pass labs amp I am entering a whole new category of audio fulfillment and realism that I have never had in my system before.

    I've owned a few Adcom amps and wish I had kept my 5500 at times just because I liked the sound character of it,. My Threshold is a big step up from there and the Pass even a good step up from Threshold, IMO. I will say from doing my research the newer ".5" versions are supposed to be warmer than the prior X versions.

    I'm anxious to see how you like the amp. If the Nuforce has XLR it's highly recommended to use them, something to do with Pass's patented distortion canceling circuit. It will describe it in the manual.
