I haven't heard them for quite some time, I would really have to listen to them again... I will state that It was probably the room and placement with all the rest of the line right there as well, but with that said, I can't say that they impressed me more then the Sigs with the Be tweeter or the Salk HT2's ribbbon for that matter. They tended to be a little laid back to me... again I would have to go back and listen to them again.
In my situation, one also has to look at the other speakers available in the line for a HT setup, and I truly didn't care for the 805S at all... I guess it would be more important if they would be used for mains, but they would only be surrounds, and there is absolutely no way I could make any of those B&W center channels work for me.... Most B&W's sound to me don't seem to justify their price IMO.
I am somewhat in a position of compromise with my setup and layout as stated, but that wouldn't make me feel unhappy with a pair of Sigs....
