anyone familiar with aurios isolation

this is an example of a metallic, hard object. its affect upon the sound is consistent with other metal objects. there is an increase in focus and a slight reduction in noise. i don't use them as i feel my stereo system does not need greater focus.

Mrtennis, I agree there is a reduction in noise and increase in focus with the Aurios and other metal ball bearing isolation devices such as Cerupucs, Cerabases,Final Labs Durumas, I also hear an increase in air/spaciousness around images with all the metal isolation devices. I've found that isolation feet made of other materials, such as sorbothane, rubber, Herbies, BDR cones damp that air/spaciousness to some effect. All have their place in my system, its just a matter of tuning to your liking.

I used Aurios and found some benefit. Personally, I prefer Stillpoints and Symposium Rollerblock Juniors. I use a combination of them. For a cheaper option, Herbies Isocups are very good indeed and a steal for the money.

I liked the first Aurios which absolutely needed to be on a level shelf. When you did them right, they were very good. Then the company went to a deeper concavity to allow less level shelves. These were no where near as good. Isolation is a very inexact effort. I had a good deal of success with Aurios and poor experiences with soft materials, but now my speakers are on Townshend speaker cradles which are pneumatic. Most of my electronics are on Halcyonics active isolation bases. But both are expensive although quite effective isolation devices.
