The appropriate mat can make a difference - to the good side. Don't forget to fix the mat on the platter as a kind of hard coupling. never leave it loose on the turntable - you will not hear an integrated system but two components. Don't use holy water for fixing...
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?
