We have been searching for Isolation pucks/feet whatever you like to call them for years. No exaggeration. Literally, years. We'd fall in love with the looks of some and being brutally disappointed once received.
All of us vowed never to take on another line unless they were tested and lived up to our (and we're sure, your) standards.
Finally, we found a brand that is no B.S. Their Pneupod work and work brilliantly. Put them under your input sources and you'll immediately notice more bass and air. Being pneumatic you can adjust the pressure until its perfect for your component.
We're working with them to get platforms with these built in for TT's. Something that is really needed in the TT community.
