@slaw, when I said vinyl is also used as constrained layer damping (it is also used as acoustical damping), in retrospect my use of "the" in front of vinyl makes for a too literal comparison. I have no way of knowing if "your" vinyl is exactly the same as the sheets of generic vinyl used as I described, and if you say it isn’t, I believe you! For the record (not an intended pun, but a pretty good one ;-), I mentioned vinyl being used in constrained-layer damping applications to suggest that vinyl is worthy of being considered a contender as a platter mat, not to disparage the idea.
And, as far as I know, the vinyl I’ve seen used as a damping layer does NOT have the hundreds of little pimples on it’s surface as does your mat, being of a smooth nature. How the heck do you create them, feed the vinyl chocolate and greasy food? ;-)
Thanks for the-free trial offer, which remember everyone, is available to all (except I don’t have to pay upfront ;-) . I’ve been thinking about the My Mat (surely not inspired by the My Pillow ;-), and mats in general. I had a few in the "old days" (80’s-early 90’s), but then started owning tables with an Acrylic or Delrin platter (VPI HW-19 Mk.2, Townshend Audio Rock Elite), which were designed with the idea of the LP being in intimate contact the platter, for vibration absorption and dissipation. You know, the ol’ mechanical impedance matching for the transfer of energy (vibration in this case).
I asked Brooks Berdan if he could get the mat John Bicht was supplying with his Versalab tables, but he wanted a fortune for one. That was like 25 years ago, and I hadn’t again thought about mats until you introduced yours. Being a fellow Townshend Rock owner, and a former fellow HW-19 owner, I feel we’re coming from the same place. I’ll be in contact.
