Isolate It: Sorbothane Vibration Isolation Circular Disc Pad 0.5" Thick 1.5" Dia. 70 Duro with 3M PSA - 4 Pack

These Sorbothane pads worked wonders for stabilizing my heavy equipment, effectively absorbing vibrations that used to cause constant rattling. The 3M adhesive is incredibly strong, making installation a breeze while ensuring the pads stay exactly where I put them.

Sorbothane is really the way to go to stop vibrations. Although it seems expensive, it solves the problem and your Turntable will sound so much better.

I love these and have several sizes and ratings all over my Hifi rig - under speakers, stands, amp, rack, CD transport......everybody's happy. I just wish they had a better way to search their products and zero in on exactly what you want, it's like beating the bushes to find the right size/duro combination. In the seller's defense, I'm pretty sure this is an Amazon problem. Hey Amazon, how about some real UI improvements?

currently using 4 of these to support a heavy hvac machine. They are carrying quite a bit more weight than their rated capacity. They are very squished, but haven't split or cracked yet.

These really do work good to isolate turntable pads from table surface

I’m using these in conjunction with RDS cones and cups under heavy floor standers. Placed under the cups it made a big difference over just the cones and cups. Bass tighter treble cleaner. More space between the layers. No smearing. Musically much nicer, although you might miss that out of phase bass smearing the music. Music is easier to listen to. Hear the speakers not the floor.

I received a package with 4 feet, but one had clearly been used before: It was cracked, and was stuck to the inside of the plastic bag as the 3M protective cover wasn't anywhere for that one foot. Returned for a refund.
