I own a MF2500 and I think that it sounds better then the Premier 11a it replaced. Its just as smooth in the midrange and rich and lush except ever slighty cooler. I think Conrad-Johnson makes some of the most satisflying equipment out there. I owned the Premier 14 preamp with the MF2500. I'm selling my MF2500 right now after only 1 month of use because I have a AWESOME deal to buy a Spectral system for 70% off. Spectral is far more detailed but not as musical, I'm going to have to get analog with the Spectral to match the CJ with Digitals smoothness
