How much torque does cutting lacquer need?

[JHL]

Hi Everyone,
i am a VR user and planning to upgrade my systems to cutting lacquer step by step. I did some research and found out SP 10 MK3 and MK2 may be the best choice?

SP10 Mk3 has the same torque as SP 02 which is used on neumann systems, but it is more expensive than MK2
i heard someone can cutting master and dubplate on SP10 MK2 as well,but i am not sure if SP10 MK2 has enough torque to drive a 14'' platter?
how much torque does cutting lacquer need?

Many Thanks!

Get an SP10 mKII. Perfect easy to find and good price. For me the MK3 are overkill, a bit harder to find and therefore overpriced.

I second this

Thanks for reply!
but SP10 mKII 's toqure can drive a heavy 14'' platter prefectly like souri's precision motor?
so why other pro master disk cutting system still need a extremly high torque TT like Mk3 or SP02 or Flo's TT15?

I've got an SP15 on my VR. Previously had a 1210 with Souri's platter. The difference is instantly noticeable, almost as much as the difference between with platter and without. Tighter bass being the first thing I noticed. I sometimes found the 1210+platter struggled with some transients unless the groove was very shallow. I've cut some 1k tone that I will have a look at and upload the results. I imagine an SP10ii would be even better.

The inertia is the key, not the torque. Pro cutting systems have a high torque because they have an heavy platter, high torque with light platter will create crappy records.

If you use it with the precision platter you can modify a SL1210 for more torque or use the external motor. The the new SL-1200G / GR have a better motor (less vibrations).

thanks for reply!
so SP10 Mk2 can drive a proper weight platter to cut master,but if i wanna have high end sound i should have higher torque TT and heavy platter.
Am I understanding correctly?

I prefer to stay away from the term "High End", we can't measure that. We're talking about great turntables here they are all perfect for cutting nice masters. we're comparing in the range of 0.0xx% WRMS (JIS C5521).. none is going to hear a difference.

late reply here, but I wanted to throw yet another opinion in

I've been watching the prices of M3's over the last couple years, and they seem to be coming down,
there was almost never one under $10k before and I've seen them as low as around $8k now,
expensive, yes, but also one might want to consider the resale value would be pretty good,
so if you say, upgraded your whole system to a Neumann or Scully, you'd probably get a
good price for it.

This deck holds value in the used market, I think new they were around $3k USD, so have actually appreciated.

going on memory here but
I think the platter weight of the M3 is 20 lb.'ish and about 10 on the M2

I agree speed stability is very important, kind of guessing here, but based on my pathetic
mechanical engineering knowledge, if you take something recorded with a tiny bit of wow
on it, that is magnified when played on a conventional record player, but M2 might be
good enough in this case

someone correct me if I'm wrong

I would imagine the value of the SP-10 mk3 has fallen somewhat since the SP-10R came along. Why would anybody other than a collector (or a lathe troll) want to pay 10k for a 40 year old turntable full of proprietary CMOS devices when they could get it's modern counterpart for the same money?

EDIT: FYI though the torque spec of these two tables differ quite a bit, inertia is around 1 ton/cm^2 for both!
