I agree with wushuliu, I had both and attached to a PS Audio DLIII. The V-link was no slouch, definitely better than the Hiface I owned earlier on. The DI + PSU just seemed to open up the soundstage a bit and the mids were punchier. It was obvious which one was better in my system. In your system one may sound better. Also, the V-link has an optical out and the DI doesn't, that may be important to some. So, given the price, if I had to choose one it would be the DI but if you wanted something immediately that is going to sound pretty good I can recommend the V-link. The DI popped up on the for sale forum after I bought the V-link. I was happy with the V-link, the DI was the only other one I wanted to try in the <$200 USB to S/PDIF converters.

But paying the same for a DI is a no-brainer.
