If you want to try something to really tighten the 805's, go to www.audiopoints.com and order the replacement 1.5" screw-in Audio Point spikes, then get six 1" regular Audio Point spikes and place three between each speaker and the stand. If your 805's are screwed into the stands, go to the hardware store and buy longer screws. Don't tighten the screws to the speakers, just seat them so they'll hold the 805's in place. I did this to my B&W Silver Signatures, and it was a nice improvement. If you do this, make sure that you get the coupling discs too.
