I don't think you'll get any feedback with the Cary's : ). Actually I don't know what they are doing these days. And technically I believe there is feedback in any amplifier design somewhere. I've heard one or two of there's and wasn't too impressed, I'm on the SS side like Khaki8. My current amp is a hybrid, but if i could only do one it would be transistors. I won't say anymore 'cause the debates gone on long enough. But I would audition at least one or two nice SS amp-blind maybe. Ya, the tubes will have a warmer, mushier sound, but its not accurate and also compressed with lack of power. My two cents.
