I am fairly certain it is the preamp. I have run my Denon 4802 receiver as my preamp as a test only to discover it sounded better than my BP20 in this setup. I am definitely interested in tube preamps (Rogue 99, ARC LS15, BAT 3ki) and I am looking for other peoples experience.
Preamp for Bryston 3BST / Magnepan MG1.6QR
I am interested in people's experience with preamps in a Byston/Magnepan setup. I currently have a Bryston BP20 that results in a very thin and cold midrange. I am looking for something fuller and warmer. I have read good things about the Rogue preamps with Bryston amps, but I'm interested in how the Magnepans stir the mix. Thoughts anyone?
