I agree that the best sound comes from a good Carbon/graphite mat firmly attached to the platter with adhesive tape. My current favorite is the Boston Audio Design Mat 1. I'm in the process of orderring the Mat 2 which is 5mm thick as opposed to the 3mm of the Mat 1. These are also more affordable than the copper mat I tried which sounded muffled in comparison.
Best mat choices for high mass metal turntables?
I've recently changed analog sources from a VPI Scout to an Acoustic Signature Final Tool. I'm curious if other owners of similar high mass, metal turntables have preferred their tables with mats or with bare platters? I've researched this forum and the Vinyl Asylum, but most responses to mat questions have centered around acrylic platters and tables of lesser mass. I notice that another similar design turntable, Acoustic Signature, supplies a laminate mat of suede/acrylic. Any owners of those tables care to comment? The mat supplied with my table was the ubiquitous thin felt variety which sounds horrible to my ears. Sucks the life out of the highs and muffles the bass. I'm running the Final Tool with a Garrott Optim FGS moving magnet cartridge. I find the sound I'm getting now to be a serious upgrade from the VPI Scout. However, the Scout does have a slightly more fulsome and fleshed out lower frequency range which I quite like. I'd like a mat that at least preserves the current tonal balance, if not lending a smidgen more emphasis on the bass. This preference makes me question the suitability of the Boston Audio mat considering other reports. At this point, Herbies Way Excellent mat or maybe a leather laminate mat seem to be the most likely candidates from what I've read. Ideas?
