The hard acrylic mat
The hard acrylic mat represents a significant improvement with respect to the original Oracle Groove Isolator that was used by Oracle until the end of the 80’s. The acrylic mat is machined with a slightly concave surface which helps flattening of the record more efficiently when using the Oracle record clamp. The acrylic has very similar vibrational energy transmission properties than the vinyl used in records which minimizes its contribution to sound coloration. Listening tests have shown better results in transient response, stereo image and provided more control and detail in the low frequencies.

Scroll almost to the bottom. It's reassuring that you were probably referring to the hard rubber one I have.
If anyone out there has tried the new acrylic Oracle mat; please let us know how much of an impact it made!
