Thanks for your perspective, Sburton.
Were I at the Cary factory, perhaps my experience would have paralled yours. However, with the Cary CDP, preamp, and DeVore Fidelity speakers I heard them with, the sound between the two amplifiers was markedly different. I am not sure if the statement quoted to you was 100% true, as the only component changed out was the amplifier itself. Perhaps they are more load dependent via transformer and coupling cap differences, etc., and the speaker I listened to showed that more than what you one heard? Again, nice to have your insight.
