@pbnaudio Yes, all SME platters come with self adhesive Isodamp SD125 (~3mm thick) mat installed at the factory. They also diamond turn the surface for a nicer finish as well as a better interface with the record. SME orders the mat material directly from Aearo Technologies (EAR).
Michael Percy sells the Isodamp SD125 material by the foot (it’s not cheap), so a DIYer can order and cut out a mat to experience some of what SME engineers do.
Best material for a mat that I have personally heard. It’s also great to dampen chassis, motor, etc. with.
