Yes, the high 1MOhm resistor could provoke common mode distortion.
I think this is one reason a high input impedance Fet opamp is advisable.

The 2nd highest distorting amplifier is the LF356 (it's JFet) (figures 2 and 3)

The input of the LF356 is not cascoded so the OPA627 ( or similar ) is better.
People reported improved sound with the OPA627 in the servo of the Paradise in comparison to the OPA134 and that may not be only the lower offset.

I'm still convinced they also cut out the fragment of the beautiful naked woman who passed by in the footage.
I need some help choosing a tt to substitute my rega planar 3. I like the rega planar but i can notice sometimes the speed variation, i was thinking in upgrade the motor, but maybe is better to get a new tt.
What you guys think is better ? A clearaudio emotion or a clearaudio champion with a rega RB700 tonearm?

Clearaudio champion with RB700 tonearm, the tonearm on emotion is actually based on rega design.
But myself i have to say that i dislike both arms since they do have magnetic antiskating - i always perfer with wire instead, much easier to setup and i just like it better.
If going for a clearaudio tonearm i would try to find a Unify, which is a nice sounding arm.
I have owned four different Clearaudio TT's and liked them all. But it all depends on what you are used to. 🙂

Thanks, I always use the rega planar 3 , and stop for a long time listening to vinyl, but thanks to Joachim and miib i start again . the cartridge that I use is a Accuphase AC3 that i like very much . So i have little experience with tt.
Accuphase AC3 i have not heard, but from what i read it is a very good cartridge - and probably deserves a higher end tonearm.
If i where you i would buy the Champion/RB700 and later sell the RB700 and upgrade to a Audiomods tonearm (it's also based on rega parts, but a completely new arm) you can sometimes find them on ebay and forums for sale for good prices. They are especially easy to dial in, if they have the micrometer upgrade (it's for vta).
You can either buy a DIY kit, or buy a complete arm - check them out at audio mods Rega arm conversion kits and DIY mods

One thing that I do not like in the champion is that it has been altered to fit the rb700. Is this a problem if in the future i want to change the tonearm?
The audiomods arms are rega mount i think, and satisfy arm i also think does have same mounting distance...
It always depends on what alterations have been made. Also, clearaudio still sells new armboards - but they cost a leg. (i think new ones cost around 250EUR).

This just came in handy, as a helpful remnder
EQUALIZATION PRIMER
Joachim and I are preparing for the upcoming travels - all in November
Krefeld, Vienna and ETF
Jacco - hope to see You ( remember , this time its Berlin not France!)
I will use a selection of Joachims Phonostages at those shows - Stig( Lyra) is coming to Krefeld and Vienna.
....
but his goes "sort of" without saying
