Is it necessary to go to this extreme like the air bearing flywheel ?

An externally hosted image should be here but it was not working when we last tested it.

Is it necessary to go to this extreme like the air bearing flywheel ? What do you gain by this ? Can u even hear it ?

Thank you for your question.
Air Bearing Flywheel solve two problems, low vibration and precise speed. Good sound system is a good part of each composition. Low level of the Analogue Source system is needed so extreme. Listen to the quiet sense of the degree and detail will be amazing.

Thanks for the reply.

I think that airborne acoustic pollution that bombard the TT/vinyl/arm will 'overcome' all the hard work you put into the air bearing flywheel motor unless you place the TT in another room. Is all the benefit from the air bearing flywheel motor can be measurable in test equipment or it is just in theory or imagination only ?

I always thought the string drive belt and the extremely heavy platter should take care of all unwanted vibration.

Are u saying non air bearing motor is not accurate ?

Horizontal is the time (each frame is 1 second), vertical is frequency (each frame is 1Hz).
Detection of three discs have done the test three times, averaged as a result. Two sets of data, frequency fluctuation value and Wow and flutter.

Test results

Frequency curve (test frequency 3000Hz)
Blue curve Technics SL-1200MKII (frequency fluctuation + /-7.66Hz);
Green curve Micro seiki SX-8000 (frequency fluctuation + /-7.00Hz);
Red curve Air-bearing motor flywheel (frequency fluctuation + /-6.31Hz).

Wow & Flutter (JIS C5521):
Technics SL-1200MKII: 0.025%;
Micro seiki SX-8000: 0.024%;
Air-bearing motor flywheel: 0.022%.

With all respect to the nice craftmanship, we can conclude that the air bearing flywheel does not reduce wow&flutter significantly, which was its original purpose. It looks nice and "technical", though...

Also no need to bring the topic UP unless new information added, IMHO...
