| Eminent Technology ET-2 Tonearm Owners Comparison of lateral forces on Kuzma/Terminator/ET2/ET2krebsFor those who are interested in understanding the side forces on the cantilever :Force = mass x Acceleration, where acceleration = mass/(velocity squared)If the record is 12mm out of tru... | |
| Eminent Technology ET-2 Tonearm Owners ThekongThanks for sharing your experience. I agree with Fremer.Thigpen does appear to hold patents on the decoupled counterweight. Whereas Walker uses a fixed counterweight at 45psi in the Proscenium, Richardkrebs advocates using a fixed counterwe... | |
| Eminent Technology ET-2 Tonearm Owners RichardkrebsReferring to your last post 03-12-13: responding to Dover. At frequencies below resonance the cantilever is free to push the mass of the arm sideways. This does not defy physics, it is physics. Correct In other words the cartridge su... | |
| Eminent Technology ET-2 Tonearm Owners RichardkrebsI have queries regarding your claims re the Kuzma air bearing tonearm.This appears to be unique in using a porous material rather than multiple drilled holes like the ET. This is not correct. The ET has a captured air bearing with a co... | |
| A Copernican View of the Turntable System Halcro - Have to concur with the wall hung shelf. This is one of the best bang for the buck upgrades for TT's of all persuasions in my view and well worth the time and effort. Biggest difference I noticed was a cleaner and more transparent bottom ... | |
| A Copernican View of the Turntable System I can recommend floating the motor/platter in Jello. Dont knock it until you have tried it. I found raspberry rather nice under the platter, but preferred melon fusion under the arm ( its a unipivot so it has eccentric taste ). My only concern is ... | |
| Ortofon 309 vs. SME 3012 for SPUs Pani - there are not a lot of tube preamps that can amplify MC's with all tubes in the phono. The Marantz has seen off my old Jadis, Manley Ref, Klyne ( all owned ) and quite a few others. The Conrad Johnson TEA2SE is ok for about 0.4mv up, no tra... | |
| A Copernican View of the Turntable System Halcro/Lewm/RaulYou are all arguing the same points but at cross purposes.We are measuring the groove and to measure it accurately there must be no movement between the tonearm mounting point and the platter/bearing.Lewm's argument is simply that ... | |
| Ortofon 309 vs. SME 3012 for SPUs Latinsambal appears to be using a Tron 7 preamp. The Tron phono uses a step up transformer internally for MC's already to amplify 0.3mv signal. Latinsambal might well be able to run cartridges down to 0.2mv depending on the gain structure of his p... | |
| Who needs a MM cartridge type when we have MC? Heaps of Ruby/diamond/Sapphire/Boron cantilevered cartridges available in the 80's, probably more than today.Sumiko Talisman Boron, Sumiko Talisman Sapphire sold in the 1000's/Kiseki Sapphire/Zenn Ruby/Dynavector Ruby & Diamond to name a few.C... | |
| A Copernican View of the Turntable System Halcro - The easy way for you to fix the issue is to get 3 holes cut and threaded for machine screws ( grub style ) around the outside of the centre bolt in the arm board as wide as possible ( maybe just inside the edge of the tower. Get some mach... | |
| Eminent Technology ET-2 Tonearm Owners Chris, the good thing is, if we have a bad day over here we can fly over to your place and start the day again ... | |
| Who needs a MM cartridge type when we have MC? Nandric - I think you are right. The different cantilevers have different characteristics in terms of stiffness, natural dampening and resonance. I suspect that putting ruby cantilevers for example in a cartridge that hasn't been designed for it i... | |
| A Copernican View of the Turntable System Hi Henry,I've mentioned the issue of incongruity between platter and armboard a number of times, but it seemed to fall on deaf ears. Your experience matches mine when I had the shop. Since most folk level their platter and assume everyone else is ... | |
| Eminent Technology ET-2 Tonearm Owners Chris - No I dont have the equipment, but Martin Colloms did in a Hifi News review years ago ( 1985, I think ). He measured the resonances before and after the air bearing and compared them to ascertain how the air bearing dealt with such. Typical... |
