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?

How about a tube preamp? It may be the Bryston Amp? I ran some inexpensive NAD gear with my 1.6's. The NAD 272 had plenty of power and was one of the smoother amps I had in my system. You can get the 272/162 pre for the cost of some preamps.
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.
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.
Check out the deHavilland Verve tube preamp. It can be found for less than a grand. This tube pre has amazing, warm detail. I personally use the deHavilland Ultraverve preamplifier with my Bryston 14Bsst with very nice results for my ears.
