Turntable speed accuracy

I tried it on a "DD" SP10 MK2 and it was off, no way to correct like the MK3 offers speed adjustments so the owner has to send it in.

Not what I wanted to read. I hate this thread.

Seriously: did the built-in strobe of that particular sp10 show that it was holding speed? And the timeline showed differently?

I believe there are trim-pots inside the chassis that can vary the speed minimally but I just don't know which ones. Maybe the trim-pots are for other functions. I don't have my SP-10mk2 or the manual anymore to verify that. Perhaps other more knowledgeable owners can comment on this. Good luck.

Banquo363,

yes unfortuantly. I was told he is sending it to someone to correct which isn't suppose to be too hard. I read from someone else whom posted prior on the old NVS posting in relation to "DD" issues.

Look at this being a positive learning experience and not negtive, no need to be upset.

If your table is off then you can address such, if it is off slightly I would be shocked if you can hear such anyways.

End of the day it's all about listening to music.

I agree with Atmasphere. Turntables with excellent soundstaging (and resolution of fine detail, dynamics and bass detail)are signtaures of TT's with excellent speed control.

In my experience, belt drive TT's with AC moters with ample torque and low friction fair better than DC motor driven TT's all else being equal. I think one way to improve a DC motor driven TT is to increase the mass of the platter with good torque. I suspect that is one reason the Micro Seiki's do well and why the addition of acrylic platters on top of the gunmetal sound better.

Perhaps you should listen to a good DD turntable with a coreless DC servo-controlled motor alongside you Raven AC-2 as I have?
No real comparison actually........
Our dear friend Lew wanted a moratorium on discussions of the merits of turntable drive types but I think that's difficult when it comes to the subject of speed consistency and accuracy?
We have heard of the supposedly superb accuracy of some belt-drive turntables according to the Timeline but as yet we have seen no real evidence?
Is someone able to upload a clip of one of these belt-drives with the Timeline....onto YouTube?
Perhaps you Andrew?
