I used the pre out of a B C int,it was nothing special used that way, I'd go with Ayre.
Ayre K-5xe or Bel Canto Pre3?
Finally piecing my new system together using an Ayre CX-7eMP front end with Bel Canto ref500m's for power. I hear about "brand synergy" all the time. My question is, what is a more important match, the Ayre K-5xemp to match the front end or the Bel Canto Pre3 to match the amps?
