My LP12 has always had it's OEM felt mat on the platter but I'm sick and tired of all the lint that gets adhered to the records, and that especially is irksome since I've spent a good deal of time using my DIY wet cleaning machine system to clean all of my record collection and place the cleaned records in MOFI record sleeves. Now when I put a record on the TT and give it a quick dustoff with a carbon brush, the record plays w/o dust, but when I turn it over, there is a substantial amount of dust & lint coming from the Linn mat. Today I received and installed a cork/rubber mat, but that also transfered material to the records--this time it is tiny bits of cork! I wrapped that up and will send it back to Amazon tomorrow. So now I'm on to other materials. Leather or silicone? Neither will shed, but what about the sound? For an LP12 I don't want too much weight, or I'll have to take the bottom off and reset the springs--ugh. PS: Oh, and I tried a NEW piece of felt (NOT Linn) and it also sheds, so it's not that my Linn mat is problematic simply because of it's age (1985).
