I have 4 Aurios Pro isolation feet for sale with the upgraded tungsten bearings. I used these under a PS Audio Power Plant Premier and they definitely helped improve the sound in terms of focus and imaging, not to mention gave more space under the PPP so the fans would rarely engage. The screws on the bottom that hold on the top part sometimes come out, but the top can be screwed on while holding the screws underneath (the screws require a specialized tool to tighten but they worked finger tightened). The Aurios would also work well under a heavy amp.
Selling for SOLD including shipping and paypal fees anywhere in the domestic US. These will be shipped via USPS.
