BlackSand PC question

I recently purchased two of the Black Sand Silver Reference PCs -- one for my McCormack DNA-500 and the other for my ARC SP9 preamp. I have to say that these are quite amazing power cords! There's an interesting thread out on AudioCircle...

The Silver Reference is built using a "12 AWG 3 Silver/Copper blended conductor twisted pair internal wire" (taken from their web site see www.blacksandcable.com)

I did try one of the lower end DCCA cords back in February but found it not an ideal match for my system. It seemed to add to bit too much body/richness to the mids. I did talk with Don @ DCCA a good bit about it (sharp guy), but his higher end cords were just out of my reach. I've only had the Black Sand PCs for a couple weeks now so I did not have the opportunity to compare them.
