SPDIF coax cable lengths

[SeriousPigeon]

How long a cable run can I have with high quality coax cable for SPDIF and not get any significant signal degradation?

I want to do ~10 metres, maybe more.

Thanks.

I'd use fibre myself

Would this not be very expensive, as opposed to 20 metres of a high street electical retailers finest coax and 2 phono plugs?

Coax it is then. Just need a soundcard with SPDIF output now.
