This is the best platter mat ever made, I own 2 of these, one I am using and one I am selling. Some important point by the manufacturer are: Impedance matched non resonant surface, three discrete layer isolation system, corrective tapered surface, bipolar construction, low profile and low mass.
It is very hard for me to explain how good this mat is, this mat is the best mattress for your LPs, you have to try it to understand it, with most of the LPs it is like a magic, this mat get rids of all the distortion or other unpleasant sounds that you hear. Some of my recording are so bad, but if I use this mat I feel as the recordings are not so bad.
This is a brand new item, I never used it, the only reason I am selling it because I have 2 of them.
Shipping in continental USA is $19.50.
