I own the MF A 308CR and am very happy with it. Robert Harley said in his review not too long ago something like, it had the best dynamics he's ever heard in a pre-amp. I enjoy it a lot, and use it with the matching MR A 308 CR amplifier. I'm thinking of picking up a pair of Maggie 20.1 speakers, but maybe my 19 x 16 room is too small - nice to have options.
What kind of speakers are you driving?
