I'm a not sure this will be helpful to you, but I can share several things that have enhanced my Nautilis 805's. Both Sugarbrie's stand rec's and Ohlala's sub rec's have worked well for me. I prefered the Sound Anchor 805 stands to the B&W 805 stands in my system, which is in a small room. It took a lot of placment experimentation to get the bottom-end right. Also, I have been using a REL Stadium II with the 805's, which blends well and makes quite an improvement in soundstaging. Marigo dot treatments seem to help this speaker in my system. I use one 3mm white dot on each tweeter flange (remove the wire screen to attach) at 12 o'clock and one 30 mm dot on the back center of each cabinet. The tweeter dots increase resolution/extension and the 30mm dots lower the overall noise-floor. Good luck in your search!
