have you directly compared the Halide to the V-link? I did considerable research on these two, and my findings lead my to believe the difference is quite negligible.
Why would you need to spend "A hundred or more" on cables for the V-link, but not for a Sound card. They both require a SPDIF cable. though, the v-link also requires a USB cable. Im not a big believer in cable mojo myself. I do believe SPDIF cables can make a difference, not so convinced with analog and usb.

Then there are user reviews and comparisons which seem to show in less of a difference. I admit the Halidie is likely slightly better. But to describe it as "Nowhere near as good" is doing a bit of an injustice. I'd challenge you to hear it in a blind test. In reality, you can spend 4.5 times more and get that last 2%. If I was spending that much money though, i'd just get a U3, or anedio interface.
