| Nude Turntable Project Chris.Like your Alpha leg analogy. Actually, with the other two feet, we are trying to block energy transmission as much as possible although in practice I doubt that this can truly be done. The PVC feet are softer than the plinth and the shelf, a... | |
| Nude Turntable Project Another design philosophy that one might consider is to minimise the number of joins and material changes, hence transmission speeds, between the LP/platter interface, around the loop to the arm and cartridge/stylus. Empirically it would seem to m... | |
| Nude Turntable Project Halcro.Part 2.The same reasoning would suggest that there should be only one path from the LP surface thru the chassis, shelf, to the tonearm and on to the stylus. Your present iteration has more.Thanks. | |
| Nude Turntable Project Halcro.My TT uses one fixed duralium foot with a central tungsten carbide ball which contacts the shelf. This gives a point contact much like a spike. The other two feet are PVC discs 80mm in diameter with a rebate such that the circumference only... | |
| Nude Turntable Project Hi.Typo in my last post. Please substitute the word "mechanical" for "electrical".Thanks | |
| Nude Turntable Project Gentlepeople.The debate between those that like compliant type supports and those that go for the hard supports has raged on forever. My view is that if you have a suitably still shelf, hard is the way to go. From reading here it seems that those ... | |
| Eminent Technology ET-2 Tonearm Owners ChrisAm I up and running?Yes and no. I have a loaner compressor, so I have music but it is very noisy and does not pass your stylus on a stationary record test.I will do the compliant CW arm and spring test once the proper compressor arrives. I ha... | |
| Eminent Technology ET-2 Tonearm Owners Dgarretson.I look forward to your tests on stiffer carts.Also re pivoted arms, I argued inelegantly a way back that the offset angle on a pivoted arm has a multiplying effect on the effective mass as seen by the cartridge. That is, the cartridge i... | |
| Why will no other turntable beat the EMT 927? Dover.Thank you again for your interest in my upgrade, re the "woolly" comment, you are quite correct. Please refer to my web site where this phenomena is specifically discussed. It takes months for this trait to settle, whereupon it becomes super... | |
| Why will no other turntable beat the EMT 927? Dear DkarmeliI totally agree with your assessment of the SP10 MK3. However this is, IMO not a result of its design, the use of a servo, or DD. I believe it is the way it is built.The tension, greyness and lack of ebb and flow, can be significantly... | |
| To ring or not to ring? LewmThanks for the feedback. I wonder if say a reflex clamp with a suitable washer under the record would be superior?I'm working on a L07D now for a client and he does not have the ring. So we were looking a the options. Imagine it would be prett... | |
| Acrylic platter Nandric and Lewm.I have seen both David and Pieta and I was in awe at such beauty, such craftsmanship. Made from stone no less!I remember The Arm, way back then I lusted after it, which was irrational since I never actually auditioned one properly... | |
| Acrylic platter Nandric.I agree, there is an art in operating the CNC machines.In our CAD/CAM shop, different operators produce different "quality" even though they are using the same program. Figure that. I have dynamically balanced my composite platter by remov... | |
| Acrylic platter Lewm.I may have misunderstood your question.... Yes, I changed the motor magnet and speed sensor cup over from the original platter into a newly machined dural housing. | |
| Acrylic platter Lewm.No I am not that brave/reckless. I have the original platter complete. I took measurements from this and machined up a new magnetic housing. Re acrylic, I think that the trick is to get to the higher transmission speed material thru a minimum... |
