Adcom defintely offers high value for the dollar. I used a pair of GFA-555's as monoblocks (over 800 wpc into a 4 ohm load!) with Apogee Calipers for many years. If you have current-hungry loudspeakers, Adcom amps are a good bet. I've since moved on to Bryston amps, which I think are superior, but I still wouldn't knock Adcom.
For a good bit of history, see if you can find Anthony H. Cordesman's original review of the GFA-555 in the early 80s' in The Absolute Sound. In my mind, that review kind of launched Adcom as a mass market manufacturer offering high end sound.
