Steve, does the gain feel about right with the M22? Also, how much time do you need to really evaluate a new amp for the K1000? The reason I say that, is I have one I'd suspect that would be a fantastic pair with the K1000, and with my time with it so far, I'd say it would really be hard to beat. I think I could try and keep it out when you're around next week to try and listen to it. Heck, I'm considering a pair of K1000 just to try with this amp I have a feeling it would take longer for me to judge an amp though...
