Slate Mat

About the Slate Mat

Oswalds Mill Audio’s official turntable-mat product is the OMA Graphite Mat, not a slate mat. It is precision-machined from high-grade polycrystalline graphite and is approximately 6 mm (0.235 in) thick. The supplied name “Slate Mat” appears to be a product-name mismatch or cross-contamination with OMA’s slate turntables, plinths, and equipment racks.
