Graham IC70 v. Furutech Silver Arrow

Anyone had the chance to compare these two phono cables? The Furutech is twice the price of the Graham. Is it that much better, or better at all? I'd use it on a Phantom II.

I recently installed the much cheaper Furutech AG-12 on another arm (SME M2-12R, which is terrific with SPUs), and I'm frankly amazed at its clarity, tone, dynamics, and coherency--especially for the price. So I'm curious about its big brother.

Cheers.
