Sounds reasonable.  I had a look in the usual boxes of PC bits for
the Behringer, but all I found was the box and manual.  It's here

The reason that I mentioned that USB might not be as good goes back
to when I was looking to buy an audio card and a DAC several years
ago, and the research that I found mostly agreed that the pecking
order goes: coax > Toslink > USB.

Having said all that, I'm only expecting to play audio with a maximum
48k sample rate on the T43, so USB should be fine... if it had coax
digital output to connect to the rest of my system, which is now all
coax-based, but the manual shows my UCA202 has Toslink.

One reason that I went with coax was because it will happily go
through passive audio gear, without needing any fancy optical
switches and splitters etc. (with their PSUs always switched on).  It
is a much simpler system in terms of routing/cabling etc. (and
cheaper to run/better for the environment etc).
