I don't think that anybody that knows how digital audio is transmitted

AES-EBU and SP-DIF signals are incredibly rugged, and provided the

will have *no* effect on the signal transmitted.

Can some kind soul please tell me what the impedance of a "normal"
analogue phono-phono cable is?

Not really, since it will vary from one example to another.

Holy **** on a stick, guys! I didn't mean to start a friggin' argument.
What are you lot like?

The reason I asked is that I'm currently using a "normal" analogue
phono-phono cable as a digital cable between my CD player and AV amp,
and was wondering whether or not it was worth getting a "proper" 75 Ohm
impedance digital coaxial cable. Maybe if I could get hold of some phono
connectors that B&Q satellite coax cable would be good. Your thoughts...?

If that is the question, the answer is really simple - no. You will
know if the impedance of a digital connection is a problem, because
you will get errors in the data stream that cause ticks and burps. If
you don't have any of these, you have a clean signal and the impedance
of the cable is not causing problems.
