Until recently this was Purist Audio Design’s flagship interconnect with Copper/Gold/Silver proprietary alloy conductors terminated in customised Neutrik XLR plugs with proprietary alloy signal pins and massive Contego shielding.
I purchased these cables from an Authorised Dealer in late 2007 and auditioned them in my system against a group of selected balanced interconnects. They were run in for 300 hours and then swapped in and out of my system several times over two days during the listening trials. They were consistently the best overall performer in my system. I am selling now as I have upgraded to Echole Obsession interconnects and these are no longer required.
