Direct drive vs belt vs rim vs idler arm


Is one TT type inherently better than another? I see the rim drive VPI praised in the forum as well as the old idler arm. I've only experienced a direct drive Denon and a belt driven VPI Classic.

I have learned allot first hand over the past ownership of numerous tables including the different designs mentioned and the ones I have tried I have been absolutely shocked with their lack of speed accuracy which at the end of the day all of these table designs all have in common and should have.

I could hear such in my own set-up prior to using this TimeLine tool to check such but was being brain washed by others including the manufacture suggesting this and that, suggesting it wasn't important.

I know there is allot more going on than just operating at an accurate speed but if you can't get the speed accurate from the get go then the rhythm and pace is effected "off" so the rest afterwards really doesn't matter, to me anyways and once you have heard it well ....

It's simple, your table using the TimeLine is either accurate or not.

I have found it seems that many are in denial, some don't even want to try this TimeLine in fear suggesting this or that works for them but in the end this is the real deal and so simple to use to truely view what's actually going on with the speed of your table so why fool your self in believing different.

Buy or find someone with one and check it out and maybe the manufactures in the end will work just a little harder ensuring theirs will be accurate.

Would love to see a REAL list made up of actual tables that can actually show they are holding an accurate speed for the entire side of a record both playing and not with an actual video with a time stamp on it.

The distance behind the tables all being the same just using a pce of tape with a BOLD line on it so one can see the laser location easily.

I won't mention the members name because that really doesn't matter, this person ownes the same table as I once did some time ago and was adamant his was running accurate when I suggested mine didn't and wouldn't, when I went over and checked the table in question with the TimeLine in hand which was really simple we found his was also off and in the end we couldn't get it to run accurate on both speeds either.

If your table doesn't have the capability of adjusting the speed like a SP10 MK2 I had on hand won't be an easy correction, if such in the end can even be done.

Lets not debate or get pissed off, instead lets work on that list of tables as per above with proof.

I would personally love to view such and there are allot of owners with different tables just reading and posting on this specific thread.

Happy New Year! to all :)
Peterayer,

A distance for sure is important, I have been doing this very easily for a while now and if the table isn't close to a wall I just use 2 light rulers and tape them to the back of the table stand along with a pce of paper between the two with a pce of painters and a dark line on such so it's very easy to view between so it's under 2 ft

All the tables I have tested, no worry about waiting for 20 minutes either. Most failed within a few rotations even after using the TimeLine to actually try and set the speed accuratly. I found most tables were not capable to be set for accurate speed.

Using the strob, numerous tables that were used and then rechecked with the TimeLine proved the TimeLine is a more accurate devise and all these tables failed within 10 or so rotations either too slow or too fast and that was with no stylus even on the record.

This has really left me scratching my head.
Richardkrebs,

very informative, thanks for taking the time to post.

I have learned first hand that specific tables I have either owned and/or have listened to don't meet even your number 1), not sure about the other two.

I do like what you wrote that tables need to;

1) have absolute speed stability under all load conditions.
2) have absolute dimensional stability between platter and arm support.
3) be absolutely still, with total immunity from external movement.

Can you or anyone else please provide a list of tables that actually meet and pass these requirements
Halcro,

I recall your video prior on another thread and that's exactly what I'm referring to, thanks for sharing that again.

You also answered my question in relation to how many turns should it be by lowering the three stylus onto the record, doesn't matter!

So we have one table that clearly demonstrats it holds accurate speed, any others? I'm very curious to see.

Can you show the results for your TW table, non of mine including the flagship BK would hold an accurate speed.
Dover,

what table are you using for those tests, would be great to see an actual video like Halcro provided.
