Turnable database with TimeLine

The real question is are these very, very small speed changes AUDIBLE!

I seriously doubt it!

Tape recorders and cutting equipment does not have perfect speed in the first place.

Many audiophiles like to split hairs with theory that makes no difference in real life. This is just golden ear BS!

Your choice of speakers are very suspect!

You hear "lucidity"? LOL!

I can not argue with religious theory.

There are many, many things that screw up Lp playback.

It never will be perfect!

I would like someone with the TimeLine to make very small incremental adjustments in speed similar to the speed changes due to stylus drag.

Then listen closely at these different speeds, on records that have light and heavy modulation, and try to hear changes in sonics.

I do not think these changes (during play) are audible, as J. Peter Moncrief's theory (which Halcro quotes), implies.

He was "the" supreme theoretical BS artist, in his day.

I am not a fan of servo controlled speed. The speed is wrong a lot of the time!

A properly designed turntable should run at a constant speed!

If there is stylus drag (that audibly effects sonics) , then increase the speed slightly.

I like the VPI SDS - regenerated AC - a variable Quartz crystal controlled frequency in steps of 0.01 Hz - after startup reduces voltage for lower noise - modified sine wave for smoother motor rotation.

It made a "huge" sonic difference on my TNT III, when the speed was set with strobe disc.

All the VPI Classic turntables need the SDS, even though it was originally made for the TNT line.

@Lewm

In this entire thread "NOBODY" that used the timeline and "observed" the speed changes due to stylus drag came out and said they detected "ANY audible sonic changes!'

This whole tread is about drag measurements that are "NOT AUDiBLE" on well designed "high end" turntables set up with a strobe!
