Wow. I just stumbled across this. I own a GFA555II which I bought as a demo in 1995. I've been happy as hell with it for years (presently in combo with a Mac C220 pre) but that doesn't mean I'm not looking at upgrading at some point. Surely "Edsel" is not an appropriate analogy. The Edsel was a bomb right out of the gate and the 555 was one of the best value purchases a mid-level audiophile could make for years on end. That technology would advance beyond it twenty years on is no reason to dismiss one of Nelson Pass's landmarks out of hand like that.
So I'm curious what some of the Adcom naysayers would recommend if my target budget is $4-$5K. My present inclination is to go with the Mac 252 as I like the solid-state/tube combination. My present speakers are B&W cdm7se and I've got the 803d's in my sights somewhere down the road.
