Help identify Apature Accusound rca cable

I recently purchased a $75 Apature Accusound rca cable off eBay and haven’t been able to identify which cable model it is. Attempts to contact Apature were met with a return-to-sender email. Cable is in a brown, very stiff encasement. Red and black heat shrink over gold rca ends. Anyone have knowledge on this cable? Materials used, retail, sonic characteristics?

thanks!
