Isolate It: Sorbothane Vibration Isolation Circular Disc Pad 0.5" Thick 1.5" Dia. 30 Duro - 4 Pack

I use these under my 60th Abnniversary AT turntable, see pic. Since i was able to listen fairly extensively prior to receiving and placing these, I can say with confidence they reduce the audible booming from theturntabke that can result from big vibration, ie my sub is directly to the left of that stack. While my sub is on a small size Auralex SubDude II (highly recommended if you have a basement or crawlspace), there is some significant vibration at times. The soundstage overall is quieter with these in place. I think they are a reasonably priced addition that does, in this use case, make an audible difference.

Didn't see this in the product description, but these are oily and stick like putty might on all sides. I was surprised, especially when they left big, greasy circles on my wood table top. Those did wipe off with water, but would have been nice to know in advance.

I put these on the lath & plaster wall behind my Target turntable shelf. Easy to install. The pads stuck to the back of the shelf and stayed there while I screwed it on to the all. Worked great. Cured turntable rumble about 90%.

After 6 months I discovered these pads were stuck to my cabinet shelf like super glue. Absolutely ruined the finish on both sides. This was under a wooden base and not exposed to heat or humidity or any other unusual circumstances. Just sitting on a shelf in a conditioned room. Completely unacceptable. (Picture included)

Maybe for home use. In car they melt.

These seem ideal for things like speakers/subs, but depending on your setup, it can also help things like a turntable.Initially, they didn't show much difference when I was using an Ortofon Concorde body and their "Arkiv" stylus; however, some time later I upgraded to a Ortofon 2M Black (and also moved my setup around).Not sure if it was the move and/or the 2M Black (or the combination of the two) but I figured I'd try these again to see if there was a difference.To test I monitored my "recording levels" while the needle was simply contacting a record (not playing the record though....ie not rotating). The noise floor was visible on the recording meters and doing things like touching the desk, jumping, putting foot down heavily, etc would register.There was considerably less movement in the meters when the turntable was on the sorbothane pads.

For my turntable it made it hard to keep balanced and square as each pad was too soft and collapsed at different rates.

The bet i believe out there for vibrations
