Various Bearing Isolation Devices

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.

The topic mentioned just above ,dated 7/21/00 is here at Audiogon under Sound Advice.

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?

Recently acquired MIB Aurios for my CDP and DAC. I was truly amazed at the immediate difference. Bass was much much tighter and the treble smoother and seemless with more bloom. Music became so effortless and made me feel more at ease too. Depth also improves. Unfortunately, I have no other isolation devices with which to compare these. I definitely hope to "float" all my other components. Pricey, though, at nearly $300 a component! MIBs require meticulous levelling to realize their isolation benefits. One hassle with these is when using a chunky custom power cord on the same component - this tends to "brake" the easy to-and-fro movement that is so critical to the bearings. Interested to know if others have had similar problems (ie using either the Symposiums or MIBs together with a "fat" powercord) and how they have solved this?
