Bearing Isolation "Arms Race" Begins

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.

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.
