I had a 555 21 years ago. Found it a bit hard and sterile back then but it sure did drive my Acoustats. Probably same with the pre. I think many newer intrgateds will sound more musical than the Adcomn pair.
I've heard a couple different Adcom amps, they were always a bit harsh IMO. I owned the Creek for a while, it's a very nice amp for the money. It would probably be a step up.
