I have a one month old Audio Sensibility Signature Silver DC cable, in 0.3m for sale.  The source (power) connector is the Farad compatible GX16-4, and the destination connector is Oyaide 2.1mm.  This is the top of the line DC cable from Audio Sensibility.  If you snoop around, there are lots of very positive comments regarding this DC cable, and it is "the cable" to own if you are using a Farad Super3.  I use this with my Farad Super3 LPS.

Unfortunately for me, I miscalculated on the length as the 0.3m is not quite long enough for my preferred set up, so I had to order an identical Signature Silver in the longer 0.5m length.  

Basically, I burned the cable in for you over the last month (free of charge, you are welcome 😃).   The cable is "as new" and comes with the original paper work.  I can also provide documentation of my purchase from Audio Sensibility last month if you want it.
