You might go another way altogether, try the Vibrapods under your cabinets. Instead of being rigid, the are compliant and dissapate the vibrational energy rather than just allowing select frequencies to pass through as all rigid feet do. You should hear more detail and less distorion with the Vibrapods, and they only cost $6 each. The Vibrapod #4's hold up to 64lbs per set of four. I believe the Stratus Gold's weigh about 90lbs each. Is this correct? If so you would need 6 pods per speaker for a total of 12. This would cost you $72 There is also a #5 which hold up to 28lbs each. Then you would need only 4 per cabinet or a total of $48. You may find that the #4's will do a better jod, since the cabinets will be more evenly supported-more of a lower compliance pod usually sounds better than fewer higher compliance pods. Also due to their vinyl composition, you wont have to worry about scratching your floors.
