Atmasphere, technically there is no such thing as no feedback in an electrical circuit and hence a zero feedback amplifier, can you quantify your statement ?
Loop negative feedback is what I was referring to. I have no issues with degenerative feedback as it occurs in real time.
Foster_9, with traditional SS amplifiers using feedback and operating class AB, you are not going to find a lot of difference in the sound. So older amplifiers are indeed an option, but making sure the electrolytic caps that occur in the circuitry are actually good will be important. In this regard the HK Citation 11 and 16 were decent amplifiers- sounding very much like many modern amps for a fraction of the cost. But you had better know a technician that can service them out, as their filter caps will be shot by now.
Another amp that seems to stand out is the BEL amplifier. It was a well-made amplifier whose designer died too soon.
