I am using a Bent Audio TAP TVC with my Bryston B100 SST (amplifier is the 2B SST) with great success! The 28 dB gain of the B100 helps give me adequate headroom. The transparency shines through with Bryston amplification. I think the 3B and 4B SST would sound just as good if not better.
The Bryston B100 preamp section is just as transparent as the passive pre and makes using a separate preamp quite unnecessary given how good the built-in preamp is!
