I never liked the original mat that came with my Technics SL1200, and I have been trying out different ones. Having worked on/junked/replaced many a mat over the years, I have assembled a nice collection.
The mystery to me is finding a mat that isn't to soft, so as not to suck out all the little detail of a recording, and not too hard, to let any kind of table mechanical noise thru. Sounds like it should be easy, but it aint.
Just wondering what you guys are using....
