LP -12 Felt Plater Mat

I heard the Boston Audio Mat1 on a friend's LP12 & it made a big difference.

As Drjoe mentioned, it was designed using the LP12.

Read the reviews:

Funk makes the Achromat that is sold by Acoustic Sounds. The VTA will need to be adjusted to accomodate the mat which comes in 2 different thicknesses 3 or 5 mm. There has been many different discussions concerning aftermarket mats and the LP 12.

I used an LP12 for years and had excellent results with the Ringmat. Way better than the felt. It had no negatives in my system.

I just restored my LP12, and am still using the felt mat. A number of poster's are saying various alternatives are "better" than the felt mat. Can somebody describe the effects of a different mat? Is it "better" or just a different "flavor", so to speak?

Happy New Year

As always I appreciate your responses.
I am not familiar with "Herbie's Way" or Boston Audio so more info on this would be nice.
I tried a ring mat and with good sonic results, but I returned it however because I could not justify paying that price for what I felt was construction paper with cork rings, and 2ndly, it was an aesthetic mis-match for my LP-12 platter.
