Does speed stability even matter?

The cutting lathe that cut the lacquer most likely had speed fluctuations due to the drag of the cutting head during highly modulated passages. Unless your turntable also exhibits speed instability during these passages, the recording might not sound right.

Producing a rock solid turntable in terms of speed stability seems like shooting yourself in the foot because the cutting lathe probably wasn't so stable. If it was, however, why not just build current "SOTA" turntables with drive mechanisms, bearings, and platters, similar to cutting lathes?

I mentioned this over on the Audiogon thread. It raised some eyebrows but got strangely quiet soon after.
