I currently have a copland csa28 amp it's about 20 years old and badly in need of a service. I was just wondering would I be better of saving my money and investing in a new Cambridge cxa81.. I know this may be almost criminal in some quarters but I'm wondering if new equipment at around the 1000 pound mark is equivelant to the old top of the range equipment. Any advice or help would be greatly appreciated. Thanks M
A lot of people think old gear like amplifiers of the good old days are better than today's that don't appear to have the same build quality. That may be true in general, in terms of build quality but to me that's mostly in being heavier, larger/heavier heat sinks, more metal than plastic sort of physical things. In terms of electronic advance, use of ICs vs discrete components, consistency in specs/tolerances, I do trust the more up to date gear.
The CSA28's specs appears to be:

Not bad for a hybrid amp of the late 90's, but I do think it is better to save your money and get a more modern integrated amp. I wouldn't consider the CXA81 because I doubt it could match the performance of the CSA28 that is in top shape.
