I think I've said it elsewhere in one of the forums, but it's worth repeating.
Try granola bars, original oats & honey in the green box work best, with 1/2" layers of Jif peanut butter in between, 6 pieces high placed perpendicular underneath the speaker wire every 24". If you don't hear a difference go to 20" apart and then if still no difference, go in 2" increments until the sound just blooms with clarity. When you hit the right point, you will know it, it will hit you like a ton of bricks - the sound will just open up 3 dimensionally. It's kind of like setting up a Vandersteen speaker or planars/electrostatic speakers. The speaker/speaker wire connection seems to dictate how far apart the granola bar/PB spkr wire lift has to be. Generally, I've noticed bookshelf speakers can use less granola but floor standers need more granola.
This is the most amazing tweak ever!
