Dover,
I kind of like the idea of not placing lateral loads on the platter bearing....and this arrangement is working so well I don't know what there is to gain with the one motor?
What harm do you think there is if the two threads touch? |
Dear Raul,
It's good to get your feedback.
It appears that your Acoustic Signature keeps consistent speed (without any stylus drag).......so I agree with you wholeheartedly that absolutely correct speed as in 33.3333rpm is not essential.
And if you read some previous posts.....you will see that is discussed at some length?
It's interesting to read that your Denon is 'spot-on'......as so far.......it seems from anecdotal evidence on this thread.......direct drives are the only ones which consistently can make this claim?
I also agree with you...that well trained ears are our best tools :^)
Cheers

Lew,
You both 'heard' it :^)
I think our descriptive language pertaining to audio......is subjective and ill-defined by convention?
I also have doubts that others here......really understand what people mean when they attempt to describe their impressions? :^)
Sorry......I missed your Lenco story. Is there a link? |
Perhaps the silence is telling us something It may well be? Whilst we have heard anecdotal evidence that some belt-drive turntables......for instance the big Micro Seikis....can maintain consistent accurate speed according to the Timeline.......I have never seen any visual evidence (via YouTube?) of this? If anyone can post a clip of ANY belt-drive TT able to do this with cartridge playing and not playing......it would put to bed any doubts? |
Halcro - welcome back. Australian politics has been very entertaining of late. Are you putting your hat in for Foreign Minister Ha ha.....thanks Dover. I don't think the Foreign Minister NOR Prime Minister will somehow pass the Timeline test??! Really looking forward to your tests with the Timeline? |
Hi Albert,
I have seen exactly that phenomenon with the Timeline on the Raven AC-2 driven by a slipping thread.
I know exactly what is happening and it is borne out by the laser mark AND the sound at the very same time.
The Timeline is its own reward :^) |
I sent the amateurish YouTube video of my TT-101 with the Timeline to Ron Sutherland who was so impressed....he said he was going to include a link on his new web site.
Ahhh....fame at last :^) |
Dear Raul,
It is rather strange that the ability to maintain accurate and consistent speed for a turntable whilst playing records.......appears to be the hardest feat (for most of them) to achieve?
I would have thought that this is the primary (sine qua non) quality and function of a turntable?
Perhaps your idea of Manufacturers selling turntables with a 'Timeline Certification' could sort the chaff from the wheat?.......but are there ANY manufacturers of current turntables able (or prepared) to do this?
I think in the end.....it is up to each user. Caveat Emptor?
Regards

Albert and Lew,
You don't specifically mention it......but I assume the SP10-3 maintained its speed with and without the cartridge tracking the groove?
Also Albert......you don't specifically mention if the NVS passed the Timeline test with equal aplomb?
Lew....have you tested the Kenwood L07-D with the Timeline? Even if you don't have a tonearm mounted....it would be interesting to know?
Also.....I have seen almost nothing regarding the speed stability of Idler Decks vis-a-vis the Timeline?
Will the Timeline not sit on the Idler spindle at all?......even if it doesn't sit all the way down, can't you manage to somehow 'wedge' it on? |
Thanks Albert,
A thoroughly lucid and objective opinion........from a subjective point of view.....which is all we can really have after all?
Right Nandric? :^) |
Perhaps the key to the accuracy and consistency of many DD turntables.....is their inbuilt ability to monitor the platter speed against a quartz crystal timing device......and make instant corrections for any deviations?
I don't know of any belt-driven turntables able to do this?.....nor for that matter....any idler decks either?
My experience with belt-driven turntables and the Timeline.....is that one can set the speed controller to be fairly stable with no cartridge playing OR with a cartridge tracking the groove.....but they are two different settings?
The 'stylus drag' slows the actual platter speed.....but as the motor controller does not know this (it is only putting out a constant signal)......there is no compensation?
Alan, have you tested your own Micro Seiki SX-8000 with the Timeline and when you say that Syntax's RX-5000 kept constant accurate speed......did you see this with and without a cartridge in the groove whilst not adjusting the motor controller? |
Hi Dover,
Congratulations. Good to hear :-) |
I agree with Banpuku about hearing the effects of record centre eccenticities.
On mt Victor TT 101 DD turntable.....which demonstrates admirable speed accuracy via the Timeline.....I am more aware of this phenomenon on certain records than I am when using the Raven AC-2 belt-drive. |
