Wolfgand, alledgely Impedence 
A single ended Digital RCA should be 75 ohms, as is a lot of TV coax 
but also the the sockets must be the same too, if a correct coralation is to be achieved, now not all rca/bnc sockets are 75 ohm 
but does this matter, will be debated to eternity :SLEEP:
Also fully balanced XLR cables are 110 ohm, but will only give their best in used in a 'true balanced' circuit design.
Now some of the best cables I've listened to, arn't 75 ohm but digital cables can and do have a serious say in your system's preformance. I am some what tainted here as I have a vested interest in cables.
But, having preformed a lot of reaserch in this area, I'm confident enough to say, virtualy every analogue cable we've tried as a digital subistute, hasn't made the grade, but however you may like the sound it gives. WM

I agree, I have a number of so called 75ohm Digital IC's that sound far worse than a simple twisted pair of silver plated copper in a ptfe jacket. I feel that this is another area of hype, and you can make significant improvements using alternatives that do not need to break the bank.
I've not heard WM offerings so can't comment, but the experiments I've done show that even cheap CDT and DAC can be provoked into a more musical response with "better not nessesarily more expensive " digital IC's. My last design is on the DIY section under DUCK ! It relatively cheap and effective.
To reduce the lack of 75ohm connection fit a pulse transformer as close to the DAC input as you can. This also makes a very cost effective upgrade, hence the Isotrans also in the DIY section.

Zanash, I wasn't actually making a comparsion to Omiga Audio cables
(would be unfair to do so) There are some top notch cables out, that really are some thing else, (as well as our own ).Best cable (Digital) I've heard has an impedence of 98 ohms
rather odd, but true. WMthanks for the explaination guys.
found this link http://www.epanorama.net/documents/wiring/cable_impedance.html
that is the limit to my understanding. guess i will not make one myself.
any digital cable you know have the correct 75 ohms impedance?the one i have now is by Ecosse Reference Producer cable.
