A Copernican View of the Turntable System

Ct0517, Sorry but it is the other way round. But he has huge potential as is obvious from the MC thread: 'Damn it! Me making the same error by nature (aka German) again and
again'.The problem is however not the quality but the quantity. To be regarded as humorous you need to make more jokes than just one.
The Moldavian plinth is still by the customs. The Dutch are
probable learning from the Americans...

Regards,

Dear Ct0517, sorry - I was serious ! Life can be kind .... sometimes. But it took me a long time to find that particular girl.
Kind of copernican journey in itself....;-) .... much harder than audio - at least as rewarding.
Cheers.

Whilst researching the Rockport Sirius III I came across this treatise written by Peter Moncreif of the International Audio Review which for me, is the best description of the 'job' (and difficulties thereof) of the turntable I have ever read.
BELT VS DD
The most stunning point he made......one which never occurred to me......was that the record itself provided only 50% of the information required to produce the music's waveform......Amplitude. The other 50% required.....the Time Domain....is provided by the turntable.
This is an unarguable fact and thus puts, I believe, the turntable firmly into the 'software' category of the analogue chain rather than in the 'Hardware' category where resides the arm-base (or pod), the arm, headshell, cables and cartridge?

Halcro,

I'm not sure if his argument about the sole role of the tt (by which he champions the Sirius III) does actually move it into the 'software' domain. Anyway, not to claim that Moncrief had any axe to grind but respected former Rockport owners self-confessed having sold their Sirius III tt's to get a Technics DD.

Spectacular speed consistency and wow and flutter control are all demonstrable on other tt's than the Rockport: not to mention an unarguable ability to avoid sounding 'grundgy and veiled'. My personal experience also denies me the ability to accept many of his a+b=c conclusions, as pursuasive as these often appear.

Just my two pence worth

As always

Dear Halcro, what is missed - almost entirely - in the whole discussion about turntable drive mechanism, is the one paramount conditio qua non that the movement of the record shall be absolute.
This does - a priori - eliminate ANY drive, which features speed control. Furthermore it disqualifies ANY drive where the transmission features ANY elongation.
It however still leaves the turntable in the "hardware" category....;-) ...
Cheers,
