I'd be interested if you find anything - I've seen a few balanced analogue
<-> CAT5 boxes (I guess doing AD/DA?) but they are very expensive. I
suspect that 110ohm AES/EBU cable is a similar price to CAT5, and its
easier to run than coax IIRC.

FWIW you can get optical boosters that will send Toslink signals over 30m
or so, but optical cable is no easier than S/PDIF coax to run.
