It's not quite as simple as that. The actual vinyl has "give" in it, meaning that the walls of the vinyl contract and expand - causing a certain amount of compression that happens in the vinyl itself which sounds attractive to the human ear. It's called "Wellie" (coming from the visual image of a kick up the bum with a wellington boot). If you go above clip in digital you get a terrible distortion but in any analogue medium it givies it more 'wellie'. That's why certain recording artists deliberately go from their digital master onto 1/2" analogue tape to saturate the tape which gives it a much better "warmer" sound - and then transfer it to CD from THAT. And many rock artists only record directly to analogue multi-track tape and then use the Apogee UV22 process to achieve analogue-like "warmth" on CD. The mastering process on the CD is the most important : there is a *big loss* between original analog mastering to digital - unless 24-bit mastering is used (which is already available). A well-mastered vinyl 12" can contain harmonics up to 30 kHz, which would be chopped dead on CD at 20 kHz. Brick wall. I * np : The Black Dog Live In Toronto (*** thanks!!)
