Does a turntable mat make any difference?

It's not a huge change in sound but I replaced my original felt pad on my VPI with a rubber one. It did help reduce the static electricity I got with the felt pad.

Sota's mat is also the same durometer and mechanical impedance as vinyl and 1/4" thick. I do not think they sell them separately. The silent needle test also works best when the record is firmly clamped to the mat by either vacuum, reflex clamping or CS Port's trick with the heavy weight and concave platter. I remember as a child listening to the needle talk of my Zenith Portable. Remember the Cobra tonearm? It even had eyes painted on it.

Signals and Moving Pictures are classic records. Gavin Harrison, Dave Weckyl, Billy Cobham, Tony Williams, Jimmy Chamberlin and Bonzo are/were great drummers. Lee Morgan is my favorite trumpet player. Tragedy that he left us so young.

I forgot Terry Bozio.

It takes approximately 4 mm of adjustment on the bearing side of the tonearm to make 1 degree of difference on SRA. ( angle of the stylus)We can play from 100g to 200g records which have different thicknesses without any adjustments.
My point is that it does change the sound not because of the difference in height but because of the of the change in VTF or cartridge weight. Most people think it is because of the change in SRA. If you want to play with mats go ahead just measure the VTF after the change so you are comparing apples to apples. I feel the included record mat is like the power cable that comes with your phono stage. it’s there to test that it works. In the end it is up to your ears, the only ones that truly matter.
