| Eminent Technology ET-2 Tonearm Owners John47 - you misunderstand how it works. It is not magnetism that provides the dampening. It is the eddy currents created when the arm moves across the magnet. Read thishttp://en.wikipedia.org/wiki/Eddy_currentEddy currents (also called Foucault c... | |
| Eminent Technology ET-2 Tonearm Owners Richardkrebs/Chris : Magnetic Dampening vs Mass.I have been away on business and my responses have been brief. I can now expand on my previous comments.With a lower mass the arm will move more rapidly initially to align with the eccentricity of th... | |
| Eminent Technology ET-2 Tonearm Owners Chris/RichardAs per my earlier post, both an oil trough and a magnet impose a resistance to lateral movement as seen by the cantilever. They behave much like weight in the lateral plane. I have simply used weight alone.This is incorrect. This is l... | |
| Eminent Technology ET-2 Tonearm Owners Hi Chris - yes I agree with Thigpens comments, but I think Richardkrebs high mass approach throws away the advantage of the ET2 over other tangential arms, that is the light horizontal mass. The ET2 is less than 25gm compared to the 80g of the Ter... | |
| Who needs a MM cartridge type when we have MC? Raul re Japanese solid state design - considering the boards for laser guided missiles come out of Japan, I would assume they have some capability in designing competent electronics.There have been many high end SS products built in Japan that hav... | |
| Who needs a MM cartridge type when we have MC? Timeltel - before you put the big S in front of the crap, I have found it can take several months for old gear that has not been used for a while to run in, caps to reform etc. For determination of best polarity, the Goldmund methodology was to me... | |
| Eminent Technology ET-2 Tonearm Owners RichardkrebsRe: your ET2 mods. Here are a few points for you to consider. I have a view on linear arms in that the rules for pivoted arms and effective horizontal mass do not apply. In fact I have added a lead slug inside the bearing spindle 25 mm... | |
| Who needs a MM cartridge type when we have MC? Timeltel - if you ran the Signet MM through the Denon HA1000 headamp, I assume you ran the MM bypass. I cant see how this could improve the sound unless there is an active buffer at 0db, or it is altering the loading that the cartridge sees, fortu... | |
| Direct drive vs belt vs rim vs idler arm Lewm - Re the NVS servo question : please read my posts more clearly.My post of 02-04-13 explains that the term "17 degrees of freedom" used on the NVS website under the title "Speed Control" indicates they use it. I included an explanation as to ... | |

| 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... |
