First off, use Coax.
Or, better, use optic fibre which is just as cheap and eliminates any possibility of transmitting electrical noise between components.
Bull****! Tell be where you can get a 10m Optical cable for £1? Which
if you go to Maplins is all it would cost you in parts to make a
perfectly suitable coax digital.
Second, any old piece of crap phono leed will do.
For short lengths. and it really *ought* to be 75 ohm, too. That said, 6m probably counts as short.
No - For any length! In fact for long lengths your only option is
Coax.
As for length I'm
guessing 6m will not be a problem as the signal is digital.
Digital pulses can be *harder* to transmit due to being square waves. just because its digital doesnt make it easier. What it does mean is that if the signal is at all recoverable at the other end it will work *perfectly* (well, close to perfectly in the case of SP/DIF...).
If you can hear a sound with no skips or breaks, then the cable is working perfectly.
Not necessarily. a DAC could well conceal small errors in the signal.
Only it you've got a crap DAC, or the errors were so small as to make
no difference to the audible sound if the errors were not 'concealed'.
In any case, I challenge anyone to do a blind test and tell the
difference between Coax and Optical.
