No problem. Use co-ax rather than optical - it's cheaper.

'scuse me? I picked up a 3m optical cable for 6ukp.

they were selling 12m ones for ~20 IIRC.

MUG ALERT! Oh Dear Ian.

My Digital Coax cable cost me nothing, it was one of those 'free' ones
you get with every Hi-Fi box. Better still you get 2 of them, ones
colored Red and one White. Personally I think the Red one gives a
warmer sound.

Okay, I'll stop taking the **** now.... IT'S A DIGITAL SIGNAL, ANY OLD
PIECE OF ****E WILL DO (for coax)! Which is why on this group, Coax is
prefered, because it does the same thing and the cable costs virtually
nothing.

WTF are you on about? 20ukp for 12 metres of optic fibre with 'plugs' on
is not bad at all.

ILLITERACY ALERT! I said *optic fibre* not coax.

Is it? Cant say I've noticed a preference either way.

At least with the optic fibre I dont even have to CARE about wether
noise from my PC will ever reach my DAC (probably wouldnt on coax either
but I like that I dont need to care.

The Coax can *in theory* transmit more than just the wanted signal (no I
dont mean jitter). Wether it does or not is down to your individual
equipment. This is simply a non-issue with optic fibre.

I didnt buy a 12 m optic fibre anyhow - I bought a 3m one. that 6ukp was
including VAT+PnP IIRC too. Thats a good price for ANY interconnect,
even a coax one.

Ian, I think you have failed to understand how your original post was
interpreted.

You stated:
=============
No problem. Use co-ax rather than optical - it's cheaper.

'scuse me? I picked up a 3m optical cable for 6ukp.

=============

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.

Your comment interferance from the PC are incorrect. With Digital
coax, the signal either reaches the DAC intact or not. You will hear
if it does not reach the DAC properly. 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.

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?

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.

Yep, we ran SPDIF down a couple of hundred metres of CT100 co-ax the
other month and it sounded fine!.....

Not so. Digital signals, and particularly their timing, can be
corrupted by unsuitable cables. But try the cheap cable. It will
probably be OK.
