Updated:
-Harman Kardon Citation 24 (from 1988 and it still works)
-Adcom GFA 555 II (great for loud music/party system, bad with thiels and critical listening)
-Muse Model 100 (one of my favorites from long ago)
-NAD 314 (still have it, and love it in my son's room)
-Dynaco ST 70 (sweet sounding little amp)
-Bell Stereophonic Tube Integrated (totally retro tubes out the yin yang) from 50's.
-Parasound HCA 800 MK II (didn't do anything for me)
-NAD C272 (amazingly clean puncy amp for 450 bucks used)
-McCormack DNA 0.5 (sweet midrange, great bass,not very refined treble though)
-McCormack DNA 225 (very nice powerful fairly transparent amp, one of the great values out there)
-McCormack DNA 0.5 Deluxe / Smc Rev B (lasted about 2 weeks..excessively bright and annoying, seemed to emphasize sibilance)
-Aragon 8002 (stock and then modified, very good very inexpensive amp, punchy bass, open mids, recessed highs,not as good as stock dna 225 on mids/treble but equal in bass drive, to a point of course)
-Audio Research 100.2 (this could be the end of the line for me. Most musical amp i've ever had by a long shot)
