I have a Raven one and I have one on order. I will post my findings as soon as I get the mat in my table. From feedback here I believe this mat will take things to the next level.
TW Acustic Turntable Mat
From Highwater Sounds Facebook page, Jeff Catalano posted a pic of the new TW Acustic turntable mat - sourced from Japan. It looks pretty substantial. I can always email Jeff on info, but hate to bother him about a turntable mat. Anyone else have any info or cost on this new mat?
