Various Bearing Isolation Devices
After you have spent a fortune on Audio components, interconnects/cables, AC power cord/line conditioner, room treatments, and even good equipment rack......playback isolation is critical for good sound. You can only go so far with cones and soft compond feet. The new bearing designs such as Symposium Rollerblock and Aurious MIB, seem to offer the next step by offering horz and vert isolation while simultaneously draining vibration from component to base, which should be one of many aftermarket products by Symposium, Townsend, Rosanite etc which absorb vibration. CD players and turntables have motors which develop internal rotational vibration which must be drained off.........I want to buy a base and bearing supports, anyone have some feedback on what is a good set-up, regards Sam
