Bearing Isolation "Arms Race" Begins

I can't comment on the Aurios, however I can comment on your curiosity of the effect of isolation between bookshelf speakers and their stands. I use another product called the 'Feet of Silence' by Solid Tech (another bearing-type product) under CDP- very nice effect- produced better, more natural frequency extension, less smearing and a tad better resolution- you know, the usual benefits...

I also tried them under bookshelf speakers- similar positive effect. Anyways, regardless of the isolation tweak product of choice- be it the Feet of Silence; Aurios bearings; Symposium rollerblocks; etc., I can vouch for the positive effect I noticed when decoupling bookshelf speakers from their stands using these type of devices (as opposed to the old rigid 'Blue Tac em' to the stands' approach.). Just my $.02...

Please post a direct link to the review not just to www.soundstage.com. I looked everywhere and cannot find the article. Thanks

Eric, sorry my mistake I meant stereotimes.com, here is link

Must have spaced out there.

I've been using the Aurios Pro for about 2 months and it's been a very positive experience. I live in a wood frame house with suspended wood floors in an area where there are several nearby train lines. The Aurios are placed atop a 1/2" sheet of MDF on top of which I place a large Black Diamond Racing Source Shelf. A Target equipment stand is then placed upon the BDR. Individual components are further isolated by additional BDR or Vibrapod products. With this setup I've been able to employ the Aurios to isolate my integrated amp, digital processors, digital transport, turnatable and CDR. The musical effect is an increase in overall clarity and instrument separation. It takes less mental effort to distinguish between different insturments playing in unison. Notes also seem to stop and start a little quicker. I wouldn't call the impact dramatic, but it's definitely hearable and IMO, quite worthwhile.

The BDR Source shelf was the most expensive part ($1,100) of the setup. Substituting some other material (glass, acrylic, wood, MDF, granite, etc.) could substantially lower the overall cost of suspending a rack with the Aurios Pro.

Onhwy61 very good idea "floating" entire rack, did you see/read about this somewhere else? When floating rack
did you get by just using 3 Pro MIBs under BDR shelf and where you aware of the tungsten ball tweak?

I guess the question most budget minded audiophiles have is does floating the rack get you close to the amount of improvement of using Pro MIBs under every component in your rack? If you can acheive 75% of the gain by floating rack vs floating each component seperately many will opt for this route as the savings are quite substantial.....any insight here?

Did you try MIBs under speakers?

As soon as I saw this post, I thought about floating my rack. I have a Salamander Synergy rack that comes with six flat feet and there are no spikes available from Salamander. The current feet would fit perfectly onto the Aurios. It has got to be better than just having it on the wood floor. As soon as I give it a try, I'll let post results.

Megasam, I didn't do any comparisons between using the the Aurios under a single component versus under the entire rack so I can't provide any insights. My setup is somewhat cumbersome. A simpler setup would be to replace the spikes under the equipment rack with threaded Aurios. Like I said early, my experiences have been very positive, but Aurios is a only a tweak and to implement system wide, an expensive tweak. I only recommend it to people who have thoroughly exhausted other, less expensive, options.
