VPI felt mat vs aftermarket

If any reflex clamp or weight system is going to be implemented, it’s also worth noting that a proper VPI platter should allow the groove surface of a record to make intimate contact with the platter surface.

This is accomplished by machining a proper “relief” for the record label at the inner platter area adjacent to the spindle as well as at the outer platter perimeter for a record’s potential “edge guard”.

A felt mat would be beneficial in cases where the platter surface is incorrect.

You’re sporting a proper platter.

Yes, with a reflex clamp the washer (rubber) is meant to raise the record just slightly above the platter surface. The threaded reflex clamp forces the record over the washer due to the sculpted profile of its underside. As it is tightened, it forces the outer perimeter of a record to contact the platter surface. This contact patch moves closer to the lead-out groove & label area as the clamp is tightened.
