Direct drive vs belt vs rim vs idler arm
Lewm,According to the Stereophile Review of the Wave Kinetics NVS it uses a DC motor with a laboratory grade servo controller with an active ultrasonic feedback loopReference - Stereophile vol 35 no 10.

What about the latest megabuck DD turntables? I think the one from the Northwest (NVS) does not use servo correction. Is it free of the sort of coloration we are talking about? Rumor has it that it does not pass the Timeline test. From the Wave Ki...

Lewm, LawrenceCould I ask you respectfully to reread my post.My post addresses some points made in earlier posts about "motor slip" and "speed correction systems/servos", both of which can be present in any type of turntable or motor.AC motors hav...

I should have made it a bit clearer in the last post, most Technics SP02 cutting lathe motors I have seen are coupled to high mass flywheel/platters in the order of 70lbs/30kg.

The myth of Direct Drives and LathesDirect Drive devotees often refer to cutting lathes and make claims about the suitability of DD's for replay based on their use in record cutting lathes.I would like to point out the following :The Technics SP02...

Richardkrebs The jitter artefact, as Mosin quite correctly points out, is not limited to the Technics line, he hears it in DDs in general. Actually my testing and listening has shown it to be present in any motor that uses feedback be it local fee...

Nandric - do you have a ranking for your MC's at this stage. Am very interested to hear what you think of the Magic Diamond. The Kiseki Silver Spot I know well so if you do a comparison to that then I can work it out from there. 
Who needs a MM cartridge type when we have MC?
Timeltel - I use the Naim grounding scheme, which essentially is only use 1 outlet ( to get grounds as close together as possible ), and sequence the components into the wall starting with power amp and concluding with source. This lowered the noi... 
Vintage DD turntables. Are we living dangerously?
I would surmise that Mahler's Symphony No2 would sound very good on Banquo's Victor.

Well I guess I'm lucky, as I bought the NCG 25 years ago. 22 years ago the NCG was PCG for me as I acquired 2 OMG's.I say to Raul keep on going, keep up the good work, so far I've saved $1000's.I hope Raul can get to my OMG before I expire so I ca...

RichardkrebsRe Your post on the 24/1I have alluded to another problem with speed stability in DD TTs that is unrelated to stylus drag or cogging...It occurs at much higher frequencies... Taking it away however is dramatic. It also shows that we ca...

In_shore - The centre disc method you outlined is flawed. It assumes the record is round, which often is not true. Therefore the diameters are not consistant. The groove is what is round, not the edge of the record.The file method I suggested in t...

Yeah should be a cracker of a match. Murray has definitely stepped up a cog - not so many kangaroos in the top paddock now.Is that your Porsche ? Very very nice.

Halcro - exactly that. If the hole isn't in the centre, then drill a big one. Position the record so that the arm is not moving in and out from the centre.Definition of run-out - oxford dictionary - nounslight error in a rotating tool, machine com...

You can fix the off centre hole by checking the run out and carefully open up the hole with a needle file to centre it. Then you simply mark with a pencil on the label which part of the elongated hole butts up to the spindle for next time.Option 2...
