I've owned the 535, while my father still owns the venerable 555 after all these years.
To my ears, these 80s/90s Adcom amps are a touch dry, and a little grainy. If going budget SS, I prefer the B&K ST-140 which has a warmer sound. Of course I really prefer tube amps, but an Adcom is certainly better than most mainstream receivers.
Also agree with the poster above - the lower preamps - GTP-400, 555, 565 - aren't the greatest either. I once owned a 565, and coupled with a vintage H-K Citation V, was a dry, rather unpleasant combination.
