But once its digital it won't be as good, right?
by "good", i'm going to assume you mean "that vinyl sound."
if this product produces a high quality digitization of the vinyl - "mastering-grade" would seem to imply this - then the resulting digital file should sound virtually identical to the original vinyl, including "that vinyl sound."
don't forget amplification: if you run your turntable through a tube amp, you'll want to run the digital file through that same amp to get the sound you're used to. also, you'll want a high-end soundcard. it would be silly to spend time, effort and dollars on a good digitization setup only to playback through a laptop's 1/8" headphone jack (i.e. the built-in soundcard, which is invariably not up to the job).
some studio engineer/producer type, can't remember who, once said "i use analog for its sound, and digital for its non-sound." a properly made high-quality digital recording should be indistinguishable from the original source. analog, on the other hand, introduces subtle distortion - but in many cases we find that distortion pleasing. it adds things like "warmth" and "character", vs. digital which is perceived as "cold" (as in it doesn't add any warmth, just what you see is what you get). abbey road has a sound, pro tools does not.
