CSPort Turntable speed control

Dear @sksos  : What did CS port did it it does not matters because the fact is that " terrible " spedd deviation.

About TT servos you already read it what I posted in the other chauncey thread and I know due that you posted there too. Well down there I posted:

""  and we have to remember that all the cutting machines in the recording proccess comes with DD motors and all those motors control its speed by servo. That means that if we can't be aware of the recording used servo then it's no trouble at all."

Lewm owns the SP10MK3 with servo control for speed and this MK3 in several ocasions was used ( the motor ) by cutthing lathe machines. You can ask lewm if he can detect something about servo and he owns a high resolution room/system.

No one can do it. TT colorations always exist, certainly not by the servo but again at the end what counts are the facts and CS Port ( with out dimishing the designer. ) been short in that overall speed issue.

Dear @mijostyn : SME 60 and its new tonearm is unique, this is not more of the same and a gift by SME for who can afford.

I’m not saying that Dohmann is not good enough. Dohmann took an after market platfform and made some modifications on it for its TT. That makes me to believe is not in anyway superior to the 60 but for some time you are in love with Dohmann: good.

I was not aware of that anecdot between Fletcher and SME.

I owned Fletcher " The Arm " that was a copy of the Switzerland Breuer design and if I remember manufactured by Jelco. Other " curiosity " on Fletcher was the original Sota Mat where the blend materials were not invented by Fletcher but came from a third part that never shares with David the formula of that mat. The today Sota Mat looks like the original ( I owned 2 of them and were just fabolous. ) but it does not performs because the blend materials are different. No, I’m not trying to diminish the Flecher high reputation.

Btw, that " sligth blowing " with phono with ears really close is something weird in your system . My phonolinepream Essential 3180 does not shows that " blowing " not only with my 95db speaker sensitivity but does not do it in Guillermo ( close frend. ) room system that by coincidence owns the top model of your electrostatics and the JC-1 but till today my 3180 only is at my place. Lewm owns the 3160 as other gentlemans and other the 3150 that was the design with what we started.

The 3180 is a true up-grade over the 3160 and in other thread I posted that we will manufacture a few 3180 that I think is a must to listen due that you are a way demanding MUSIC lover/expert audiophile.

Dear @chauncey  : Fro several years SME was the side line of an Aero Space corporation and that test/spec speed is part of that very high technology/engineering legacy.

That SME 60  sspeed test is " formidable " in any BD TT. Numbers like that were reserved for DD vintage TTs as the Technics SP-10MK3. If you really are interested in the 60 you can't go wron with it. This is the Technics speed:   R

Dear @chauncey : SME always been a sinonimous of truly high quality designs and excecution on those designs. The 60 is the Ultimate TT for any one no mtters what and with the advantage that comes with a new SME tonearm. About its control speed SME uses DSP technology as you can read in its site.

Now, what is the main target in any TT at any price must be: spin accurately at the RPM 33.33/45 and stability on those RPM. You can read in SME site too that the speed error for the 60 is: -0.005% .

That’s is quality that any serious audiophile and MUSIC lover are looking for. All the other TT overall characteristics are in secong place/step that that speed stability.

In other side you can always mate the 60 with an after market vaccum hold dow mechanism.

If you can afford go for it. You can’t go wrong with the SME 60.

I don’t know why @mijostyn on TT’s always recomend Dohmann when he likes in other areas SME.

Btw, the Dohmann is motitoring continuosly each secon its RPM speed to make the changes need it and in this specific regards I think that the SME60 is better. The Dohmann speed error is -0.01 % and in no other measurements is superior to the 60.

Dear @lewm  : This is what CS Port says about the motor rotational speed:

" a highly accurate voltage is supplied to the motor without fluctuation based on a crystal oscillator with high frequency accuracy.  "

They use the word " accuracy " but not exactly by the TT speed stability that's in true inside " mediocrity " by CS Port spec: where the rotation precision is:

+,- 0.3%. This means that that TT has a swing of 0.6% on speed precision  ! go figure what you pay for that TT  $$$$$  !  ! I don't give it a " dime " for it.

I don't know what do you think about? and the owners?

Regards and enjoy the MUSIC NOT DISTORTIONS,
