One way that comes to mind is to convert the stereo signal to digital
and send the digital signal over the balanced pair. This might be an
overly-complex approach -- so it depends on how much you /really/ want
to preserve the stereo signal. :-)

One chain I can think of is:

Analog[Stereo] --> S/PDIF(unbalanced) --> AES(balanced XLR)
     --> S/PDIF(unbalanced) --> Analog[Stereo]

There's several $40 devices out ther for the analog/spdif conversion.
The spdif to AES conversion could probably be done with a couple of Hosa
CDL-313 boxes (about $80). (But I'm new to SPDIF and AES so I might be
missing something.)

A cheaper way that *might* work to send S/PDIF over XLR is to run the
S/PDIF signal through a couple DI's. Since the S/PDIF signal is pretty
resistant to noise -- I think this is pretty likely to work.
