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

Mike, why did you replace Rosinante with granite, was this your idea or did Visitek recommend this as surface for Aurios MIB? I thought you were happy with Rosinante, please fill us in......Sam

Megasam, At first I tried the Aurious with the Rosinante Dark Matter Shelves, but the Auriuos was not leveled properly. This sounded good. In an effort to save money, I did my darnest to level my SACD player with the $500 Rosinante Shelve and on a $6 piece of granite tile. The net outcome was the MiBs w/ Rosinante wasn't any better that the granite tile. In fact, I seem to loose some of the low end bass output using the Rosinante. The Rosinante seems to add its own flavor (maybe it injects its own resonent frequency). Since vibration in the xy direction is 99% of the problem, there may not be a need the Rosinante Shelf. Besides I now have extra funds to squeeze more performance out of my system employing another tweak.
