Avoid 80s carver gear...poor reliability...FWIW, in a second system I have a Carver M400t, which still works like new after 25+ years of light to moderate use. For a number of years during the 1980's I also had a C4000 and a TX11, which were completely reliable.
The M400t "cube" amplifier, whose design was intended to emulate the sound of a Mark Levinson ML2, is, despite its small size, fully as powerful as its 200W rating suggests. Its sound quality is certainly very competitive in its price class, at least with speakers that are easy to drive (I have no knowledge of how well it can handle difficult loads). I would not recommend its predecessor, though, the M400a, which is quite poor sonically.
