Great response, Unsound! I very much appreciate your insight and assistance. While Pass and the Krell FPB series are both out of my (initial) price range new, I have seen deals on used amps from each that are within my realm of affordability. And ultimately, my goal is to build a system that I can be happy with for some time, so dealing with the Adcoms a little longer, and saving up some more cash, is preferable to playing the multiple upgrade game.
