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

Euphorbia, did you go for tungsten carbide bearing upgrade for rollerblocks (I bet you did) and what is difference in sound?.........Marlec, CD player/turntalbe are first priority, Delve Audio is selling "B" grade Aurious MIB 3/$250, check their add on this site accessories/tweaks/classifieds...........also go to stereotimes.com and read 6/12 review of Aurious MIB, Symposium platforms and rollerblocks were reviewed in Stereophile last year, regards Sam

Hi,Euphorbia,Megasam nailed my source and the price that I paid.They can be a little tricky to set up.Check the topic,"Aurios Media Isolation bearings yes/no",which is dated 7/21/00.Mikeg turned me on to these bearings.

Talked to Cable Co today, they said Symposium will soon be offering "super ball" for rollerblocks. The current tungsten carbibe upgrade ball is round to within 12 millionths of and inch, new supper ball using even more sophisticated processes, acheives perfect round within 5 millionths of an inch, further reducing microscopic friction, life is good........still waiting for my back ordered rollerblocks, regards Sam

My rollerblocks arrived finally, and I put them to the test. Beautiful looking precision pieces, I got the tungsten bearing upgrade and used the drop of teflon/silicon oil tweak. I used them on a Symposium Platform Shelf under a Musical Fidelity CDP, set in a Target VR5 rack. When installed CDP will float effortlessly and easily rock back and forth with light touch. Sound becomes more solid and clear, bass is faster and firmer, imaging and transients improve....... the important thing is sound is very natural, no upward tilt was noticed (unlike many cone devices).....this was my main fear. These units have a permanent home under my CDP! This is a very elegant system that solves CDP isolation by providing coupling/decoupling both at the same time. I would like to have compared to Aurios MIB, I think both are probably good solutions for CDP, becomes expensive to deploy on multiple components though........any other people using these?
