Zero feedback and class A,which is better?


hi I am in the market for a integrated amp I have a pair of Martin Logan Aerius speakers(non biwire type)What is more important to quality sound,class A amps or zerofeedback amps?Is there any amps out there that do both? I know that Simaudio is zero feedback and class A for the first 5 watts which just confuses me cause I don't think with logans i will ever use such a small amount of power,How do tube amps figure in this equation? cayin has a ss amp that is pure Class A, so far I am leaning to buy this Cayin 265ai amp,any advise thanks,Nick

That's a good question, and I'm hoping some of the amp manufacturers that lurk hereabouts will post a response.

Many SET amp manufacturers and at least one OTL amp manufacturer combine zero feedback and Class A operation in the same package (three of the six amplifier lines I carry have both characteristics, so obviously I voted in favor with my wallet). I think that Nelson Pass's "First Watt" solid state amps do as well.

I'm under the impression that the Aerius has a fairly nasty impedance curve, which can work against such amps. Can you tell us anything about the impedance?
