anyone familiar with aurios isolation

thinking of putting a set under my amp. can the amp be set on top of the aurios or is it better to put some kind of shelf ( maple or granite ) on top of aurios and amp on that? fhanks for any advice concerning this .
You can do it either way. Your preference will determine which method is best.
also! you can try moving then around..try 2 at the back and 1 in front then reverse..there can be a difference in sound depending on the piece of equiptment..usual recommendation is the heavier part of the amp gets 2 and the lighter get the 1.Something you have to experiment with.
thanks for your response-are they easy to set up and do they improve the sound enough to even consider geting them? thanks
They are most definitely an effective isolation device, although they are not the only isolation device I use.

As for amp use, I currently have my amp stand spiked directly into four Aurios, also have my amp sitting on 2 Aurios on top of stand. Spiking the stand into the Aurios was a definite benefit vs. Aurios only under amp and amp stand spiked into floor.
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.
