I would highly reccomend the Grand Prix Audio racks. I have recently added a rack and some amp stands in two different systems. The benefits of these devices was simply amazing, really you'd have to experience it to believe what these can do for a system. There is a lot of science to back up their claims as well. After experiencing the improvments the Grand Prix racks make I move the importance of vibration control in a system up a notch, especially with top notch electronics that are capable of very high resolution. They aren't cheap, but what they will do for your system makes them a great value.
Also excellent is the Sounds of Silence Vibraplane. Source components benfit especially from the Vibraplane
