The Extreme is a very thin carbon fibre mat that can be used over a felt mat, over an  Extreme none-felt mat or just on your platter.  I tried it on my Linn and, as always, preferred the plain old felt, but that's me.  You may love it, as apparently many others do.  Sells for $119 + shipping.  Sell for $75 shipped in the lower 48.  Paypal only.  No extra fees.  I used the mat for 1 day, so it's as new.  Thanks for looking.
