If you want to get the best of your transport, try this.


http://www.symposiumusa.com/rollerblocks.html 

I had used these three roller blocks under CEC TL0x for 5 years about 15 years ago and now I am using them under Jay's Audio CDT2 Mk2.

There are two different balls. If you can afford, the super ball is recommended for more effect.

With these roller blocks, transport give higher resolution and sharper focus.

I think it's effect is more than good digital cables.

But I recommend combination of roller blocks and good digital cable to get the best of your transport.

Well, they are cup shaped. It could be that the photos don’t depict how deep the cups are. They are convex. And as I mentioned, the older site showed top halves that matched the bottom halves with the ball bearing in between. If you are concerned about it rolling up, over and out of the cup’s lip, then you could ask for a top halve to ease your worries.

All the best,

Nope
Not worried at all about the bearing rolling out of the cup, think you may be missing my point.
With say all 3 bearings freely spinning in the bottom cup bases, anything placed on top WILL slide on those bearings very easily.
At least that is my take on it from an engineering point of view.

@uberwaltz I know what you mean.I tried an off brand similar to rollerbearings and the component did actually slide right off of the footers.It was a cheap "knock off" product though.The rollerbearings must be a much better design I'm assuming since so many people use and recommend them.
I have my components on sand platforms.

Symposium’s second Roller Block, named "Jr,", contains a top and bottom cup, circle-shaped with a diameter of just under 2". Symposium’s original Roller Block (still available) came as a single cup, rectangular in shape.

Ingress Engineering now makes three versions of their roller bearing (the company’s website pictures all models), the best two an improvement on the Symposium design (imo). The bowl is cut to a larger diameter, therefore being shallower will less steep walls, for a lower resonant frequency (I believe). The aluminum used is also the harder 7075, rather than the 6061 Symposium uses (as does Ingress in their original, bottom model). Their original model is still available, and like the Symposium Jr., consists of two cups.

Geoff is of course absolutely correct; roller bearings provide no low-frequency isolation in the vertical plane. Neither do spikes! Lots of people consider spikes and cones to be isolators, when they are in fact couplers (at very low---below 10Hz or so---frequencies). Don’t blame the messenger ;-) .

I have one set of the Townshend Audio Seismic Pods (under my Townshend Rock Elite table. Max Townshend, a very clever and creative designer and engineer, used the Pods as the suspension in the Mk.7 version of The Rock), and will be getting more; gotta sell one of my vintage drumsets : ( .
