What are the audio differences you hear with turntable Mats.

Just a caution when comparing mats… they must be exactly the same thickness or the tone arm must be adjusted to compensate for the additional thickness… or I guess thinner is possible. If you are not carefully adjusting your tt then the outcome may be pretty random.

That makes sense, if by that you mean, if it sounds better, then you can make appropriate adjustments to optimize it. 
 

I have to admit, I am very shy about throwing my turntable out of perfect adjustment. My audio guy adjusts it.
