Talking on the phone Alan said essential exactly what you said. He definitely respects Mike Z. and his business. If there was a collaboration between Alan and Dr. Z... well that'd be kick ass to me. I consider both amp companies to be the best amps available - bare none. I have 2 Carol-Ann's and 3 Dr. Z's. For different reasons for each, I can't really tell you any of them is my favorite. I simply have favorite ones at different times... They're all amazing.
