I used to have Def Techs all around. I moved the BP-30's I had up front, to the surrounds, and still have a CLR-1000B for the rear center. (But I'm going to 7.1 over the holidays, yee ha!) I have Vandersteen all up front now, with a V2W sub.

Def Techs and the 950 (and my Acurus amps) go very well together. I do have more hiss from the Def Techs than the Vandersteens, but the Def Techs are a little bit more efficient, and I think in general, my hiss problem is more due to the interaction between the 950 and my amps than the speakers.
