When I'm talking about bite, its not really impact or attack. In this particular case, I mean that the CD has a different tone due to (afaik) distortion and being recorded 'hot'. It is a more etched sound. Grain. Usually the last thing I want in a recording, but thats part of NIN's charm sometimes. Its really difficult to pinpoint or describe accurately (at least for me).
Still, if I could have only one version, it would be the vinyl transfer, no doubt about it. I forget the origin of my copy of the vinyl transfer, because it was given to me. From someone possibly reading this very thread
