Actually, now I remember, I got mine for =A31.50 as a 'repaired' bargain in
their bargain bin... but it would still have been a bargain at normal
price!

Can't recommend that- I'd expect you'll get noticable bleed/crosstalk from
the serial data line to the audio one.  Like most of these things, it might
work, but my engineering-guessometer is swinging towards 'probably too
noisy'.  Go on, splash out on another cable! =20

It won't actually damage anything (at least, that's what my guessometer
suggests- there's technically a very slim chance that it will appear as RF
into your amplifier, which could be amplified, which might cause your
amplifier to overheat, but that's fairly unlikely)

If anything it will suffer noise on the audio when you transfer, and
possibly interference to the data line from the line level signal (though
the latter isn't very likely- crosstalk gets worse at high frequencies, and
a square-wave data signal contains high frequency parts)

Just not very effectively- I thought it was Stuart who had asked the
