Bob Carver tube amps

I’m not sure how you can find what you found online and still consider Carver. He’s been a gimmick salesman for decades. If nothing else, look at the claimed power output to weight ratio of his recent tube amp lines, and compare to other brands. That speaks volumes (way-undersized transformers). There are other options, even in USA: Rogue, Quicksilver, ARC, Raven, VTA / Bob Latino. Maybe also look at English Acoustics. Audio Classics has a nice-looking VAC-made 9B. I’m sure I’m missing some great options. There are lots of great sounding vintage tube amps out there which are gems with a bit of TLC. Even those 60 year old tube amps won’t disgrace their tubes by using an under-sized transformer.

15 years ago I tried a Sunfire Signature 600 that was possibly the worst sounding hifi amp I’ve ever used. Not that it sounded outright wrong or awful - just that everything else I’ve tried in this hobby has sounded better.

Besides the extremely questionable power ratings, what I find most disingenuous about the previous Carver co. was its bold proclamations for a "lifetime warranty" and "20 year tube warranty" (or whatever it was, exactly) when the average lifespan of a Carver co. incarnation seems to be 10 years or less. Good luck getting those claims fulfilled in the future. 

I had a Sunfire Signature 600 II, and remember it distinctly as the worst sounding 2ch amp I’ve ever owned in 20 years. It got used for like a week before I couldn’t stand it anymore and put back in the PS Audio HCA-2 (also very efficient, certainly no heat converter), to great relief. Then acquired a Parasound A21 - even better. Nowadays I own mega-buck amps, to great satisfaction. But if people are happy with these Carver/Sunfire amps and feel they are superior to $30K (or more) amps, I say good! More power to them! It didn’t work for me.
