I post this purely to generate some discussion.
I wonder what is inside the lump in the cable and how they think it works to alter a digital signal with a passive device.

Here's the referenced patent: http://www.google.com/patents?id=14ofAAAAEBAJ&dq=5412356
Price is a bit steep...Abstract
A single-ended digital interface cable and a balanced digital interface cable having a source end and a load end for propagating audio frequency signals in a digital format is disclosed. Each of the cables comprises a fixed capacitor or a capacitor and switch network which is coupled at or near the load end of the cables for providing a fixed bandwidth or for use in selectively controlling the bandwidth of the cables and a series resistance at each end thereof to dampen ringing.

Read the patent stuff
It's not optical !!
Well, for that kind of money, the cable could have some pretty exotic circuitry in it ... like hi-rez A 2 D and D 2 A converters plus some actual equalization filters, etc., etc...
My question would be: Why do all that in the cable? Isn't that done in the computer already ... or in the DAC ??

You are forgetting the är-”ti-ky&-’lA-sh&n.
A tweakable spdif cable is pretty much the wet dream of any self-respecting audiophile. Not cheap but imagine how much you can save by squeezing a whole cable collection into one.
Seriously, a great commercial concept. The bloody spdif thingie is so sensitive to tweaking, that even if all the knob did was compressing mechanically the cable, it would still make a difference.
By changing the characteristic impedance one can produce all types of sound.
And all of it wrong.
Are you trying to tell me you can hear a difference if a cable simply has pressure applied to it..? *LOL*

- Adjustable spdif cable? smells like snake oil to me.
