Turntable speed accuracy

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 :^)

Halcro,

I assumed the same thing you did and heard the result as reduced dynamics and slurring. Funny you detected the same phenomenon.

I agree, Ron has a winner, http://www.positive-feedback.com/Issue58/awards2011.htm

Scroll almost to the bottom.

I gave Ron Product of The Year for the Timeline. I'm pretty sure I stirred up some of this when I began posting results of my own tests last year.

The Timeline may not be a "perfect" product but it sure reveals errors that a printed disc and strobe miss. I would go so far as to suggest the Timeline supports things we hear and previously could not prove.

If the laser light stays in exactly the same place on the wall as the platter rotates but the "line" created by the laser beam gets longer, then it is at least possible that the tt is momentarily gaining speed above 33 rpm (assuming the flash of the laser is of constant duration, which is a fair assumption). But the fact that the light does not move left or right indicates that "average" speed is maintained. This is one explanation that comes to my mind; I have no idea what you are thinking, Albert and Henry. I would be interested to know.

It seems to me if the tt slows down momentarily, the laser spot would shrink, not lengthen.

Albert, I take all your points in support of the NVS, but the bottom line is what do you think of it in action? Does it blow away your SP10 Mk3?

Who ever suggested the NVS was better than any other tt was just full of hype, just more marketing blah! blah!

What I can't figure out is how does a table that list for $25k just a short while ago then jump up to $40 and now $45 or what ever.

That new wooden shipping crate must have added some serious sonics, possibly no more bent platter bearing :-)

Who in thier right mind designs and manufactures a table costing this much and then ships it with the platter attached, makes no sence.

I may have missed but has there been any mention of any owners using the TimeLine on it and the results.

Albert P, we know you have one so what are the results.

Dear Halcro: No doubt Timeline is a great tool for now. I think that the main subject around it is not only that we learn more about our each one TTs and its right set up but that today TT designers use the Timeline ( or similar tool. ) as a important part on its design and development of a TT.

That we can know that this or that TT has a " failure " about can't help enough, what can help to each one of us as customers is that today and future TT designs could come with the Timeline " certification ".

At the end that " certification " is or should be IMHO a TT's designer target not ours.

Btw, Halcro the stock MS TTs are not good enough about speed and speed stability, its motor controler are deficient about . Years ago in my unit and other units we have to make changes in there to improve this TT main desirable characteristic. IMHO and with today standards MS units are only an average ones.

Anyway, Timeline is here to stay: good.

Regards and enjoy the music,
R.
