TT mats

Another mat to try is the Funk Firm's Achromat for $100. Its secret material is foamed PVC. Identical stuff that signs are made out of. You can get the 3mm thick sheets at any sign store, or even Lowe's/Home Depot in any color and cut a circle out. They run $10-$20.

@lewm Nope, the graphite wasn't good. The music died. Sucked away by the void of eternal damping. It sounded different from other sources -CD, DVD, PC and car. All different rigs but similar sound. The Mat just robbed the music of soul. It was a gift and I couldn't live with it so I sent it back. 

I guess I'm a zombie, in that case.  To each, his own. The BA mats have lots of fans, not too many detractors.  What turntable, tonearm, cartridge?  I use the BA Mat2 on my SP10 Mk3 with Reed tonearm and ZYX UNIverse cartridge.  I also use a Mat2 on on my Victor TT101 with FR64S tonearm and a few different cartridges.  I do also like the SAEC SS300 mat on the Victor, about as good as the BA Mat2 but slightly different sonic balance.

I've got to agree with noromance.  I've used many different mats and they all were different, but not overall better to what was already used.  Certain pieces of music seemed to like one while others sounded somewhat better with another.  NO mat was superior including TTW copper mat on the platter.  Some cost quite a bit more, but were worth less.  I've had Boston Audio, Origin Live Herbie's mat, TTW copper mat (platter), Platter Pad, a different copper platter, glueing down the supplied rubber mat.  These changes were done to VPI Classic, VPI Scout, Lenco with multiple upgrades, and a Maplenoll Ariadne.  Thus far, the best sound by far was with no extra mat on the lead platter of the Maplenoll.

I'm an anti-aftermarket mat guy at this point.  I may try an Artisan Fidelity copper mat on my Lenco platter, but it's very expensive.  I'm rebuilding my 10-layered plinth right now so it can be used with the much upgraded AF chassis--we'll see how that goes.
