You can't go wrong with a Rogue 99M - it worked very well when I had a 4B-SST amp. You can find these in the $1100 range and while there are other choices it would be hard to beat at that price. ARC is also a great match according to many owners but I have not had one personally.
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?
