Ever heard of Music Mat?

Just wondering...

I have an old canadian Music Mat I recently pulled up from storage and would like to know if anyone has compared it to other more recent products like the Audioquest sorbothane mat.
Hi--- Hmmm?-- I think I had one of those--was it a dark brown and rather thick --Spectra? I've tried dozens of mats and the best I have found is the"Extreme" one from below.


Good spinning!
