I had a chance to compare the Soliloquys to the B&Ws and the 805s sounded anemic and sterile by comparison. Of course that's biased by my tastes and associated equipment interactions at the dealership so take it for what it's worth. I've never heard the Revels.
I second the warning that if any of the drivers in the 5.0s fails you're pretty much out of luck short of buying another pair of Soliloquy speakers, which is a serious consideration. As much as I like the speakers there are lots of good alternatives out there (i.e. Silverline, Usher, Hyperion, Ascend Acoustics, Epos, Joseph Audio, etc.). Then again, for 300 bucks it's not like you're risking all that much and they're beautiful speakers in every sense at that price. Best of luck.
