Never heard a comparison with the 805's & the TB2's, sorry. I DO know that the B&W's sound pretty good with Bryston. I've heard both 805's and 705's with a B60.
This is only a guess- but I'd bet the TB2's would please. I just posted on another thread that there was a review of the B60/Rega Planet/TB2 on the Bryston site. You might check to see if it's still there. It was complimentary to the synergy w/Bryston.
I'll bet James Tanner would give you honest advice....
