I spoke to Matt of the Funk firm, and he tells me it is primarily designed to fit the Technics platter (which you don’t have ) to stop the platter ring.
APM is available to buy in the store but currently on back order. It is a technics mat with a glass backing to cure ringing platter on one of the new models (not sure which )? It will go up with all information when stocks replenish in new year. (It’s on the long list)
