| Vintage DD turntables. Are we living dangerously? Lew,I think there are similarities here. Have you tried the peripheral ring with the Sota clamp? Matching the mechanical impedance of the record seems like a good idea, but only if vibrations are not reflected back. I think that's why a 5mm carbon... | |
| Vintage DD turntables. Are we living dangerously? Halcro,Interesting observations about periphery clamps. When a vacuum system is over applied it has a similar deadening affect, at least to these ears. Using a reflex clamp in reflex mode can have the same affect, depending on what's under the rec... | |
| SOTA I-clamp vs Reflex clamp You might want to consider the Michell reflex clamp. It's light weight and you have the option of using it in reflex mode. It's supplied with a felt washer that you place on the spindle under the record. You clamp down with enough force to help fl... | |
| Vintage DD turntables. Are we living dangerously? Halcro,You assume too much. My Sota reflex clamp is > 200g, but more importantly, I can use as much down force as I like and easily clamp onto the spindle putting 600g pressure on the label. I think you missed my point about applying pressure m... | |
| Vintage DD turntables. Are we living dangerously? Halcro,How thick is your pigskin mat?Do tell, your formula for success. How heavy is the weight?How can someone duplicate your results if the methodology is unknown? Is a weight more affective than a clamp, and is Mike Tyson your hero?Regards, | |
| Vintage DD turntables. Are we living dangerously? A heavy weight will only create a solid bond in the center label area of the record, maybe slightly further. I think a clamp would be as affective preventing movement of both record and mat.A reflex or periphery clamp should be more affective coup... | |
| Vintage DD turntables. Are we living dangerously? Totem,No, the weight of the record didn't seem to do anything, and the pliability of the mat seemed to create the problem, but you've given me an idea. I normally use a reflex clamp, but not in the reflex mode. In other words, just holding the rec... | |
| Vintage DD turntables. Are we living dangerously? I read on Karma that deer hide is better so I got a thin one (< 2mm) figuring a thick one would have too much give. Although it looks to be of uniform thickness results were similar to Downunder. Mild edge warps looked exaggerated and it seemed... | |
| Vintage DD turntables. Are we living dangerously? Totem395,Thanks for the info. It seems like torque or lack of, and speed correction circuitry are major contributors to SQ of various DD's. I saw a GT2000 years ago, but never had the pleasure of playing with it. If the motor can power a 18kg plat... | |
| Vintage DD turntables. Are we living dangerously? Lew,There are photos of both the GT2000 and 2000x at Vintage Knob. Stock aluminum platter is pretty hefty at nearly 13 lbs. The x platter looks similar, but is gun-metal. The motor shaft on the x is beefed up to 6cm vs 2cm for the 2000, but appare... | |
| Vintage DD turntables. Are we living dangerously? Interesting to consider torque to mass ratio with the Yamaha GT 2000. Stock platter was 5.8kg. Optional platter was 18kg and was used w/o modification. That's almost 40lb. The Goldmund Reference platter was 35lb, was said to be too heavy for a DD ... | |
| Vintage DD turntables. Are we living dangerously? Halcro,If the record/platter interface isn't yet understood or a matter of opinion, why defer to original options offered for your old table? The fact that there were options implies there is/was no one right solution. Perhaps not, but I think thi... | |
| Vintage DD turntables. Are we living dangerously? Halcro,No one has yet to provide a provable theory how or why a mat works?This stuff might seem like rocket science to you or I, but it's not. The record/platter interface is understood, but platters are made differently and people bring their pre... | |
| Vintage DD turntables. Are we living dangerously? ........or have their ear bitten off. Bon appetit. Sorry I chimed in.This has already been done by Pierre Lurne, only with a platter rather than a mat. I happen to have some sheet lead. Might see if it's doable. | |
| Vintage DD turntables. Are we living dangerously? Halcro,The purpose of a mat is to provide a stable surface with a similar impedance of the record, or so they say. Some think the best mats are forms of acrylic, methacrylate (Delrin), carbon, or vinyl. The trick is in preventing vibrations from r... |
