PS Audio Xstream digital cable. Any users?

Hello, I have been discovering that most digital cables in the $100. price range are mediocre at best, except for one. The empirical audio cable. It is VERY good. An audiophile/Tube-amp manufacturer friend of mine and I have made a couple of different very simple digital cables with great results. BUT...I came across the PS Audio Xstream digital cable website and got seduced by the blowing of their own horn. Can anyone here confirm that this is a great cable or is this just Xstream hornblowing. Thanks
