I would suggest the Classe CAP 151 (but then again I own it) for the power amp section alone. I wasn't a big fan of the preamp portion (or any of Classe's preamps for that matter), but the power amp was superb and I added a preamp (used with the amp in, bypassing the preamp) when I had saved more money. So if you want something for the long term I would suggest the Classe where it seems to me the bulk of the investment would be in the power portion of this integreated.
