Robin,
This a cut-and-paste from what John of KCI sent me:
"Yes sir I do make digital cables, two different models; one is the Falcon which is of a coaxial design and uses Japanese long grain silver and copper, is heavily shielded(triple) and is a great "bang for the buck" cable. It has de-throned many much more expensive cables and performs well above it's price point. The sound of this cable is very quick and clean with a super quiet black back ground but, this cable is not bright or lean at all, just honest. I offer this cable terminated with either Eichmann Silver bullets or Vampire BNC connectors and it retails for $399 terminated with either option.
My second digital cable is the Pegasus which uses Silkworm technology but we add a 22 a.w.g. pure silver wire to keep the speed up where it needs to be as well as to help in reducing jitter. The pure 24 karat gold gives this cable it's smooth open and organic sound while the silver keeps things "up to speed" and in check. This cable matches incredibly well with our Silkworms, Fireflies and Mandarina cables as it has the same sonic signature; smooth and slightly warm with that big open euphoric sound that the above three are known for. This cable can really help take the "digititus" sound out of digital signals and is recommended for the person who is looking to tame down their digital signal a little bit. This cables MSRP is $499 terminated with WBT NextGen Signature plugs(platinum/silver) or $399 with Eichmann's Silver Bullets(recommended and less expensive). Of course should you so choose I will gladly treat any of my cables, free of charge, on my Audiodharma Cable Cooker Pro 2.5. This treatment will not fully break in the cable/s but what it will do is give you a nice head start on the break in process. "
