Not that there'd be any point to it, or
with doing the same to CD.

Sure there is. Cutting with wider excursion doesn't necessarily give you
any added distortion. The thing about the LP is that, unlike with the CD,
there is no actual reference level and although there are hard limits on
excursion due to the design of the cutter, there are many other limits that
prevent you from coming near them most of the time.

In most cases it's the playback system that limits things; there is no reason
to cut a disc that can't be played back without skipping. But I would be
willing to cut a lot hotter transients on a disc intended for the audiophile
market than for one intended for playback on jukeboxes.

Like digital works from the top down, and analogue from the bottom up.

Scott is saying that he can get 'higher up' cutting vinyl (presumably
versus the averagely good)...

Kind of.

You can think of the LP as being slew-limited. It's not like regular analogue
media. You have more headroom at low frequencies than at high ones because
the limitation isn't -total excursion- but how fast you can move the stylus.

Nothing to do with flat tops or average envelope levels sorry thek.

The cool thing with the LP is that you can have peaks that far exceed the
average level as long as you time them right so that the peaks on adjacent
grooves don't hit one another. So aggressive limiting doesn't actually make
anything any louder (although a little light limiting can make discs easier
to track).
