Should I buy a Class A Amp.

I was a Krell dealer and also a Musical Fidelity in the days when use to have big amps like the 270 and 370 which were class A. The ones I liked best were a pair of Stax 100 watt As through Quad 63s. I don't have any As now and find good ABs sound good are more flexible and far less trouble. I am using a CJ 350 and Gamut D200 which are not cheap but I got the Gamut for less than a good Class A

I had a KSA 200 and it sounded good and would be good for power lifting practice. But check out the cost of new caps. I knew someone who had one and had not had it recaped because of the cost. There were many mono amps some of which were very expensive and forklift ready.
