What I am saying is that, Coax is always cheaper, because you can you
a really crap standard piece of phono cable instead of a far more
expensive optical one.

And I would say to that 'no, not really'.

if you buy pre-made leads you will pay at LEAST a fiver for a 3 metre
phono and thats not even counting delivery. my 3m optic fibre was 6ukp
incl. shipping and VAT.

heres an example...

Granted you could probably just jam some bell-wire in a coax port and it
would probably work for about 50p. Thats not the point though, is it?

Your comment interferance from the PC are incorrect. With Digital
coax, the signal either reaches the DAC intact or not.

Im not saying it wont. what I am saying is that the digital signal is
not ALL that can be brought across the coax - you could bring a sizeable
amount of high frequency switching hash (many digital devices use
SMPSUs) or LF hum or anything else across. As long as the peaks are
below the threshold the system considers 1s, it wont affect the digital
signal.

If the cable carries
interferance of any kind (unlikely) it is simply ignored by the DAC
due to the error correction built into the digital signal.

Ignored by the digital side of the DAC yes. but its not impossible the
noise could affect the analogue parts of the DAC.

Granted, any /good/ DAC will eb largely immune to noise of this type,
but its not impossible, and an optical link WILL remove it all.
