Does a turntable mat make any difference?

I go naked on my VPI.

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.
