I have the DSP24ve and I do not recommend it. Noisy inputs and various strange things going on with that card. If you expand it with the digital bracket for S/PDIF ins and outs, you're asking for trouble. I had mine working flawlessly for about 6 months though, before all hell broke loose. There are these irregular, loud pops going on in the S/PDIF ins... of what I've heard is a bad component on the bracket that causes these pops... it could possibly be solved by some soldering work on the card, but do it wrong and you short-circuit the whole thing.
I'm getting rid of it.
