Anyone here with Magico A3 driven by Bel Canto Ref600's?

Yes, audiotry’s opinion trumps all of the Absolute Sound editors and writers.

Mark larsen we know many of these reviewers do you honestly think because someone writes for a magazine they know more or can magically hear better?

There is absolutely nothing wrong with Ncore and Hypex based amps. They will mate with a wide variety of loudspeakers.

To answer your question audiotroy, all of them apparently hear better. It is not necessarily hearing, but in your case, bias founded in financial self-interest. For $5K, and I have owned them, the REF600M are terrific, award-winning amps at a great price. So we all disagree with your opinion. 

Doesn't Stereophile really like the REF600's too?
