McCormack DNA-750 good?

Buy them! 2009 is not old, you can always resell if you don't really like. Is it a hassle, yes, but most of the time listening first is not a realistic option. Go for it.

These were purchased pretty much sight unseen a couple weeks back, I wanted to get thoughts from people on them.
They arrived about 5 days ago, all I can say is I will never let these leave my house, maybe upgraded, these are my reference amps, and I highly doubt there is better, even if I do spend much more on pass labs class a stuff, the point of dismissing return would apply. These McCormack/Conrad Johnson amps are just amazing. From low volume listening, to the ability and aggression of a charging rhino shi*ting glass, these amps are absolutely amazing.

Detail, relaxed, etc etc, I can go on, but you get the picture. I am done for a long time with looking for the perfect amp. !!! Sigh

Well there you go. I won't be selling mine for a long time either. Now check out Fidelizer pro add that, and you will have sonic improvements.

Huh, I just found out, after reading the name on the amp boxes, these were owned by Dan Babineau.  Didn't he run the power surge/conditioner company???

Told you they are very good. Another are new Ampzilla. Had mono's, just great. Just bought Son of Ampzilla mk2. Make my Quad 2805 sound beautiful. $3500 retail just a steal.
