Ideal Pre Amp for Bryston 3B ST or 4B SST 2

I need advice, I've been told that Bryston Pre Amps are not the best and most would run a different brand Pre-Amp to a Bryston Amp. The question is what would be the best marriage for a Bryston 3B ST and Magnepan's 1.6? I want Balance Inputts and Outputts but do not want it to cost me another mortgage!

Tube or Solid State?
