Now in regard to turntables, speed inaccuracies, wow and flutter only
affect two things in music, pitch and tempo. Now since the vast majority
of us are pitch and tempo stupid the very minor variations seen in high
performance turntable is totally inaudible.
if you hear a
difference between two high performance tables it has nothing to do with
speed inaccuracies. Different cartridges, arms, cables, setups maybe
but not speed inaccuracies.
In not all but in some respects I don't think what we each are saying is all that far apart. The ability to detect timing differences is a necessary condition for assessing tempo; the ability to hear frequency differences is likewise a prerequisite for gauging pitch.
I assume you believe you're making a deductive argument.
Validity is one thing, the truth value of premises and conclusions is something else. Saying something like "
the vast majority
of us are pitch and tempo stupid" is silly.
The only thing I can think of to explain the main quoted comments above is perhaps there is not enough experience yet with high performance tables and their comparison. I write this so others interested in a purchase and who consider evaluating their choices understand that the two most critical physical/technical factors for a table are stable speed accuracy and low noise.
The Ideal evaluation of two tables is to have the only difference in a comparison be the tables themselves. Same cartridge, same tonearm, cables, entire rest of the systems and room are identical.
Critical sonic evaluation between tables is possible with a playing field level.
Under such conditions it is easy to hear differences in stable speed accuracy and noise in terms of listening to music. Granted it is unusual to read about such a comparison, but that is exactly what is found in coverage of the
Monaco 2.0 from two years ago. Here were two similar tables but with clear physical differences, both having highly stable accurate speed measurements with one set of measurements much better than the other and likewise clearly different sonic differences. Fwiw, per the standard DIN measurement, wow & flutter were unmeasureable.
