After trying quite a few, the PolyCrystal has had the most dramatic improvement. If you really want the best, the Aurios MIB's are collecting a lot of attention on that level. It is the bearing that stabilizes electron microscopes. http://www.mediaacc.com/accessories/aurios.html. But it doesn't come cheap, $300 for three. You could buy a lot of PolyCrystals or Black Diamonds for that. There are also the Bright Star Audio air inflation platforms that start at $100. No charge for the indecisiveness.
