Anyone familiar with the None-Felt Turntable Mat?

Yep. In every particular.

I always try to avoid felt mat indeed.
Becides the statics you should probably clean the record when you flip it as well.

I use an Audioquest Sorbothene mat on my AR. The prior owner told me it was Merrill's recommendation.

I tried one out on my MMF-7 and the elimination of static cling is the only improvement it offered. By the way the material looks suspiciously like the refridgerator bin liner material sold in grocery stores. In addition it appeared to have been cut and punched by hand. It was slightly out of round with rough edges. Roy Hall of Music Hall recommended the Ringmat. According to Hall the Ringmat is to be standard issue on the new MMF-9. I purchased a Ringmat and I am very pleased with the fit and finish and it eliminated the static cling problem. The jury is out regarding any sonic benefits.

I purchased the donut None-Felt mat feeling the cost was so low I could try it without worry. It does sound significantly better than the standard felt mat Linn that came with my LP12. Bass is tighter and the midrange seems has more layering. However, it does have a tendency to stick to the record. i would recommend it. It does not work on my other turntable as the platter set up is completely different.
