I have not heard the STS speakers, but I have heard many other Def Tech speakers. They have a big following of loyal owners, so please don't take offense, but to me, they sound excessively bright in the upper-mids/lower-treble range. YMMV, of course, and it is possible that my auditions were with electronics far inferior to yours, which could have been the problem. FWIW, my own speakers are in that price range. The Ohm Walsh 2000 is a completely different approach to speaker design than your Def Techs, so they may not be for you. However, Ohm offers a 120-day home trial period, so you can compare and decide for yourself. If you don't like them, you're out the shipping only. The Ohms's like lots of SS power, so I would expect your Bryston to be a good match. The Ohms do need at least a little room to breath, though, at least 18" from adjacent walls, IME.
I have compared lesser-model Def Techs to Vienna Acoustics speakers, and I much preferred the VA over the Def Techs. Smoother treble, better defined mids and better soundstage presentation, IMHO.
Just my $0.02.
