Re-issue vinyl vs. the original pressing

The Neumann cutting lathes do not digitize the signal going to the record. Later production Neumann units used extensive microprocessors to control the cutting process, but the music signal sent to the disc was all analog.

Zaikesman, go to this link and scroll down to the section about disc cutting. It's a reprint of an article by Robert Runstein. It will tell you everything you never even imagined goes into cutting a record. It's not that you need a delay, but you need to preview the signal going to the cutting head.

Hdm, thanks for the link to the articles. Apparently many vinyl mastering engineers are using add-on digital devices in order to protect their lathes from overloads which would burn out the cutting heads. It's a poor solution, but may be necessary since Neumann doesn't make or even support it vinyl lathes anymore.
