I have a two year old grungebuster turntable mat. Not much to go wrong here. I listed 8/10 but again, not much to go wrong. Your chance to save some money on a nice tweak.
From Herbie's web site:
Provides exceptional synergy with matless acrylic-platter turntables like VPI Scout that are designed to couple the record to the platter with a clamp. Although manufacturers generally recommend these turntables be used without a mat, our customers have found the grungebuster Turntable Mat brings out significant sonic improvements, oftentimes without the need for a clamp. Also a superior upgrade for Rega P9 ceramic-platter turntables.
Comparative testing with various types of turntables have shown that Herbie's hand-made, super-fidelity grungebuster mat is as sonically natural as the highly acclaimed Way Excellent II Turntable Mat, as quick as Boston Audio's graphite mat, as responsive as Mystic Mat – ascending to a new plateau of analog musical playback, unsurpassed by anything else.
Comprised of a full-size circle of Herbie's grungebuster isolation material. Textured surface grips records yet allows records to lift right off. With drastic reduction of microphonic vibrations, with the vinyl held "motionless" in its rotation, with lateral slippage nonexistent, your records will achieve a new level of superior playback. Can be used with or without a record clamp or weight.
Overall mat thickness: 1.6mm; diameter: 11.6" (29.5 cm); weight: 135 grams (4.75 oz.).
