First, I'm with you in that it's a bit of a "not again!" feeling to now have to deal with finding the USB cable that sounds best in my system. But....my experience has demonstrated to my ears that it does in fact matter and despite Al's comments above the USB cables I have heard do have a specific and consistent character (a point we have disagreed on before...ie power cables as well as digital cables... civilly disagreed!).
So...my recommendation would be the Nordost Blue Heaven, used pretty close to your budget, or the Acoustic Revive. The Blue Heaven has that Nordost house sound, uber detailed, extremely taught and articulate bass, with outstanding extension high and low. The Acoustic Revive is much fuller, more musical sound that has a very organic, natural presence. I use the more expensive Acoustic Revive that has a separate power run and it is an amazing cable...but expensive.
