Carlos - I highly recommend the SoundAnchors for the 802's. In addition, they are "floated" on Aurios Pros.
In the last two weeks I have added two pairs of Walker High Definition Links to the speaker binding posts. These are the most startling improvement I have yet to hear. The soundstage is deepened and the imaging is very focused.
My sources have largely been fellow Audiogoners. The airplanes are just one more passion. The velodyne sub really augments the 802's lower end nicely. Haven't tried stereo subs but might someday. After trying numerous Krell and Levinson amps, The new Krell "cx" series is astounding!
