I currently use a Mac MA2275 tube integrated amp with a pair of 805s's and a TAD subwoofer in a large 20'x 27'room. Being a log home all the walls are (naturally)wood with a carpeted floor. The sound is excellent and there is plenty of volume available. I run the speakers direct with no crossover. Driven by the preamp outputs the subwoofer with crossover set @ 45hz is only for fill at lowest octave and is virtually unnoticeable it does not color the mid bass at all. I was never really a B&W fan but these speakers lack the brightness that in the past characterized B&W speakers to me. Female vocals are exquisite. The 804's on the other hand sound congested & boxy to me lacking both the smoothness and open sound of the 805s's. I originally auditioned both speakers driven by a C220/MC275 combo in pretty good dealer showroom. Hope this helps.
How different between B&W 804s & B&W 805s????
I'm currently using a pair 805s and having a good chance upgrading to B&W 804s. I know that floorstanding speakers always better than the bookshelf but how different??? I'm also saving some money 4 my new amp(my target is Mcintosh 6900 or 2275), so, shoud i upgrade this speakers or saving that money for my future amp????
