Blue Dragons for HD-650?

Has anyone had experience with Moon Audio's Blue Dragon cables for HD-650 headphones? I heard from one person that the cable is quite good, but I would like as much feedback as I can get. I was thinking about getting the Silver Dragon but I have noticed that my new HD-650s are at the upper limit of sounding bright without sounding too bright and I have heard that Silver Dragons might make them sound too bright. Thanks for your thoughts.
there is a thread about sennheiser replacement cables over the next page.

i am using the silver dragon and the sound is not bright at all, but i agree that it has less bass than most people would like.
