What's the best unipivot to arm ever made?
Stuff I thought I "knew" (like certain principles of modern tonearm design) is constantly being debunked, so finally nothing surprises me. After all, the RS-A1 tonearm sounds great, and it breaks every single rule anyone else ever posited. 
What's the best unipivot to arm ever made?
Dear Mike, Thanks for the URL. It is striking to me the degree to which the Telos is a "throwback" design. I note that it uses a string and weight for anti-skate and that the counter-weight is pretty far back from the pivot point, so it does not m...

Here is a link: Go back up the thread two or three posts of mine, and you will find it. Anyway, there is no need, because I just summed up the story. The oddity is that he claims to be unable to sing a single note but to have a perfect sense of pi...

Ummm..., Dev, I think you took what I wrote and ran away with it. You can't have it both ways; either a turntable is given to you with the possibility to adjust its speed and therefore correct for any inaccuracy, or not. In the latter case, the tu... 
Turntable speed accuracy
Dear Dev, Your question was: "don't you think it's strange that a well known source who is selling these replied by saying they are close and not as you did saying it can be set to be spot on?" To that, my answer has to be "yes, I think it is stra... 
Who needs a MM cartridge type when we have MC?
Hi Rich, Yes, RM designed the Beveridge amplifiers way back when he was a youth. 
Some tables have soul and some not
Thanks, Marakanetz. The Violektric phono stage looks pretty cool. There is some possible ambiguity in the product description, but it does seem to be truly a balanced circuit. Other true balanced phono stages include Atma-sphere MP1 and MP3, Ayre ...

Dear Mab, L07D is not in service at this time. I am re-wiring the tonearm. 
Some tables have soul and some not
Marakanetz, You wrote, "Balanced isn't only 3-pin. It could also be 5-pin stereo-balanced. If the phonostage is fully balanced(recall Violectrik), you can rewire tonearm for 5-pin stereo-balanced transmission." Actually, you would not have to do a... 
Turntable speed accuracy
Henry, I've done it both ways with the Lenco and Mk3. The DP80 has no cartridge mounted at the moment, so could not do it with "stylus drag" factor. Likewise, I don't have 3 tonearms on any one tt, so could not repeat that show either. If the tt i... 
Turntable speed accuracy
Sarcher, What is the evidence that the hum is (or was) due to the motor/cartridge interaction?Banquo, I have some knowledge but not much skill when it comes to the electronics of either a motor controller (for BD) or a drive system for a DD tt. If... 
Turntable speed accuracy
Dear Uru, I am not the font of all knowledge on this subject, hardly. But what you suggest does seem logical; the speed of a tt may deliberately be set to slightly fast with no load, so that it then achieves perfect speed with the load of stylus d... 
Turntable speed accuracy
Dev, The Lenco is pretty near infinitely adjustable, as the idler wheel is driven by a tapered shaft that is an extension of the rotor of the motor. So, if the Lenco was off, it simply needed to be adjusted by moving the idler wheel with respect t... 
Who needs a MM cartridge type when we have MC?
Dear Fleib, My goat was not gotten. But it would be fair to say I did over-react. That is because I am so electro-ecstatic with the system as it currently sounds that I took the opportunity to brag a bit. I do concede that ESLs tend to roll off af... 
Turntable speed accuracy
The concept of "belt creep" and what to do about it is not mine intellectually. This phenomenon was first described to me and to anyone else who read it by Mark Kelly. Mark played at designing a bd tt to combat it. The Artemis is a less complex so...
