Artisan Fidelity Technics Sp10Mk3 Dual Layer Precision Platter Mat

Purchased a few months back from Artisan Fidelity.  This was one of their demo mats.   In good condition.  A couple of very light superficial scratches  near the spindle hole on the Stainless side.  Only visible in the right light.  Does not photograph well.  Free CONUS Shipping and Paypal.  Will only ship to a CONUS address.  Let me know if you have any questions.

Artisan Fidelity Precision Reversible Dual layer platter mat designed exclusively for the legendary Technics Sp10Mk3 direct drive.  To the best of our knowledge, this represents the first platter mat design available utilizing heat treated, aircraft grade Aluminum and Acetal Homopolymer Delrin sandwich, enabling the listening to contour their listening experience accordingly.  Technically, the record mat is universally compatible, suitable for use with a variety of analog front ends.  A note to users, the (2/ea.) holes present adjacent to the center spindle location mechanically couple the mat firmly to the Technics Sp10Mk3 factory platter, eliminating any air voids or gaps between the physical surface interfaces.

Artisan Fidelity Technics Sp10Mk3 Precision Reversible Dual Layer Platter Mat

Precision CNC milled and high pressure bonded.

Reversible Acetal Delrin / Aircraft Aluminum Sides for individual playback contouring. 

Delrin, an advanced synthetic thermoplastic, was originally invented and patented by DuPont laboratories and has been widely used around the  world in a number of applications ranging from delicate laboratory use to larger scale manufacturing. Delrin is characterized by its dimensional stability and high stiffness resulting in a stable platform, which happens to provide a unique and ideal surface medium for vinyl record playback. The Rockwell hardness of Delrin is typically R115 +/-2 and the hardness of a vinyl record lies in the range of R110 +/-5. What this means simply is that the record and mat density properties are quite closely matched and as a result, record playback is open, free flowing and un-colored. The Delrin record mats playback characteristics are of a resolving and airy nature, but not quite as "cool" sounding as most metal based record mats. Focus and resolution is also quite good and its neutral tonal balance places no particular emphasis on any frequencies.
