There may be a standard cutting angle today, but there certainly wasn't back in the LP's glory days from 1955-70. Optimal arm height on same-thickness records from that era varies with the record label and date. It's clear to me that Decca/London, RCA and DGG/Archiv, to name just three, used different cutting angles. It may even have varied from one plant to another within the same company.
Obviously each of us can take this as far as we wish, and one could certainly "set and forget" if one chose. I suspect this might be more satisfactory with rock or other "processed" music than with classical. Large scale works with acoustic instruments are especially revealing of tiny setup changes, even more so if a chorus and soloists are involved. Getting it just right really brings them all to life.
Warning: just a week or so ago '4yanx' expressed some surprise that I was adjusting for each record. Now he's doing it himself! Once you hear that sweet spot you'll want to find it on every record. Ever try just a little cocaine? ;-)
