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 somewhere... 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). -- Dave Love is a snowmobile racing across the tundra and then suddenly it flips over, pinning you underneath.
