A couple of used suggestions :
1. Mission/Cyrus 2 with optional PSX power supply. I had one of these in England and it was extraordinarily powerful with real driving bass. Detail is not sacrificed, though. Cyrus 3 with PSX is equally good but more $$$$$
2. Audiolab 8000A or 8000S : also powerful, but with less pronounced bass than the Cyrus amps. Maybe slightly more refined.
Both are well built and will last at least 15-20 years (my Cyrus2 is now 15 yrs old and going strong). Hope this is helpful.
