| Direct drive vs belt vs rim vs idler arm Lewm cc RichardkrebsI dont think the Goldmund numbers quoted are indicative of the sampling rate. I dont think you can count the number of wavy lines on a pcb and equate this to sampling rates. The Goldmund uses a coreless JVC motor. It uses a qua... | |
| Eminent Technology ET-2 Tonearm Owners You've just reminded me - I got a big improvement when I put an isolation transformer between the mains and the pumps. Much smoother sound. | |
| Direct drive vs belt vs rim vs idler arm Richardkrebs - Is this the Papst or JVC motor ? Can you explain how the speed sensor works in the Goldmund Studio. | |
| Eminent Technology ET-2 Tonearm Owners Hi Chris/GrantYes I used 2 pumps running into a 20 litre surge tank. On the pumps I used, reversing phase & neutral at the transformer inside reversed the phase on one of the pumps. In NZ you must not reverse phase and neutral at the power cor... | |
| Direct drive vs belt vs rim vs idler arm Re the Goldmund Speed CorrectionGiven that the GP Monaco checks the speed 7200 times per revolution using current computer technology and software, I would vey much doubt the number quoted in the previous post ( 34000 per revolution ) for a 30 yea... | |
| 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. | |
| Direct drive vs belt vs rim vs idler arm 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... | |
| Direct drive vs belt vs rim vs idler arm 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... | |
| Direct drive vs belt vs rim vs idler arm 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. | |
| Direct drive vs belt vs rim vs idler arm 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... | |
| Direct drive vs belt vs rim vs idler arm 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... | |
| Eminent Technology ET-2 Tonearm Owners 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. |
