Thanks for the advice. Much appreciated.
I have not tried Amazon, but since the sorbothane from eBay is especially made for enhancing audio I guess it is more appropriate for this use.
Not sure why you would think one is more appropriate than another for audio use, just because some guy on eBay lists :audio" in his auction title. Unless it is somehow counterfeited, your primary variability is hardness [duro] and form factor. Otherwise, it's Sorbothane, and you buy how much you want in the size, thickness, and duro you want. Hopefully, for the best total price you can get. Cheers!
