Dr Audio nailed the biggest issue with the Carver, from my research. He's correct, they are very well built.
But, there's an occasional problem with solder joints going bad on caps, and occasionally on wires. I doubt as common as some folk may make it out to be, but a few snuck by the quality control dept, it seems. Maybe it was a bit of lazy worker syndrome/friday afternoon soldering?
Another thing I see wrong with them, more common, is a single meter or both meters inoperative. I dunno how easy it is to fix this, or what the problem is, but there are just enough with meter issues to have it stuck in my head as a potential problem. Anyone have insight on this?
Now, as to sound, I've heard people say both good and bad about them. I've heard a few myself, and while some claim that some model Carvers are grainy, I've not experienced it. I like the sound of Carver gear very much, I find it impressive and of quality, and the earlier Phase Linear stuff too.
As for the Adcom gear, it's well-built, and solid, and good stuff too. Only one friend of mine who owns one has complained about the sound- calling it a bit sterile, clinical, no warmth. I'd venture it's more like Yamaha gear, which I own, very accurate and clean, and quality sounding. Most owners sing praise about 'em. I'd not hesitate to get an Adcom piece either.
For rumor sake, I've read here and elsewhere "supposedly" the 535 is nicer sounding than the 545 and 555 (and less common 565). I can't confirm this, but it's rumored to be true.
I'm rambling- sorry. I'd not turn down either amp- I think they are both excellent pieces, and I'm sure to bring you lots of joy.
Good luck, and keep us posted on your final choice!!!
