I’ve been always advising to get rid of the rubber mat on old Thorens turntables.
Lately, I’ve been reconsidering some of my well established views. The otherwise excellent Funk Firm Achromat I’ve been using for years looks a rather warped today. So I tried a felt mat I had spared and…. differences? Well…. really tough to tell.
It is debated whether the stock Thorens rubber mats of the 70s are still usable or not. Basically, the function of a turntable mat is to avoid placing our precious records directly on a rough metal plate. Modern turntables that use acrylic plates do not need a mat. The use of rubber in the past was due to its isolating properties and of course to their soft protection for the records.
