The standard domestic links (coax and optical) are 'one way' systems

Righto. If it's not a 'neccessary' thing, then that's fine.


Something to do with better kit does a better job of showing up
flaws, hence, really good kit sounds crap? ;-)

I'm not stepping into that one... :-)

I'm sure an oscilloscope is a much cheaper approach... ;-)


In principle, coax may pick up electronics noise, and might provide an
unintended path for something like an earth loop. In practice, I
can't say I've ever noticed any difference between coax S/PDIF and
optical. They both work fine in my experience. Co-ax has the
advantage of being cheap and easy to make up yourself.

I already have an optical interconnect for punting stuff to a portable
minidisk recorder, so I'd probably give that a go first. The DACs I've seen
for sale all look to have both coax and optical, so it's not like there's a
potential cost saving to be had by going after something without one or
other connection type.
