I've heard it with some Theil PCS's (very nice speakers)...The sound was very Nice: Fast and responsive, but lacked any depth/warmth, not a bad thing (I guess) but it seemed to be a little too stoic for my taste.. in comparison the Bryston 3B SST is another story...Bryston has gotten it right again! Balls to the wall headroom, linearity and warmth...they bring out the best in just about any speaker they connect to...
Congrats on your new purchase! I just bougnt a Mei-Xing MC-7R valve rectifier tube preamp (www.mei-xing.com). I switched out the stock chinese 12AX7's with some NOS Telefunkens and its the best dang preamp I've ever heard, very stylish too! I am trying to convince my wife to buy me some Magnepan MG 1.6's for xmas...oh yeah!
