Thanks Frans for this nice little thingy.
I,m glad to be of service (One Is Glad To Be Of Service - YouTube), the DA/Buffer looks nice.

Stefan Joachim is the one with the many cicuits so he's the one to comment on the differences.
The paradise circuit is NON-feedback...you can create the Neuman pole by inserting a resistor in the riaa network, as it is here it track the riaa curve beyond 300 KHz, It has a slight lift of app 0.5 dB in the deep base, this is deliberate and within RIAA tolerances, but can objectivity be adjusted by lowering one resistor in the RIAA network..

The problem/challenge in the starlless-Sampler circuit is how to keep the two benches from drifting..Its not to my knowledge possible to servo the two separate balanced outputs.

Yes, a common mode servo is possible. The ones i know are in the signal path though. I use
such an arrangement in the FPS i did for Jan Diddens Linear Audio. It is in Bob Cordells book.
Comparing the Paradise R1 to R2 there are differences. The older version is kind of cozy and inviting. Nothing sticks out as any bad so it is well balanced.
I have several phonos here that sound quite similar with less complicated circuits so i would say that the first Paradise is very good but somehow the very complex circuit may not be necessary.
The new version is much more dynamic, open and exiting. The quality of the bass is extraordinary. There is a lot of punch and drama. It also worked right away so it is much easier to build then the older version. I am definitely recommending the R2.
It is one of the finest stages i heard, no matter how expensive.

Hear the master's voice.... I don't claim to have golden ears but could not agree more..... It certainly saved me from spending BIG money on worse equipment!

Now the problem is with the turntable and cartridge...

I have ears good enough to be quite certain when i hear something that is out of the ordinary. The R2 is such an ear opener. Better still it can be build without much to spend.
The only exotics are the 2SK170 JFets. I think in the constant current sources they can be replaced with other N-Channels with a small modification to set the idle.

I beg to differ (in a way). In my opinion there is no problem (never bin), all these items in the audio chain are like musical instruments. The chain includes, the original instrument, its surroundings (music hall, cafe ...), the audience (more people is more damping), the microphone, the recording device, the mixing device, the person doing the mixing, the information caring device (LP, CD, tape ...), the playback device (pre-amp, amp), the loudspeakers, the placement of these, the listening position, and the listening surroundings (most probably I forgot some).

There is only one place where the sound is/was like original, and that place is at the start of the chain. There is only one place like home, and that is at the end of the chain. Whatever you do in between it will change the sound, this change can be destructive or it can improve the original (at itís input). It will never be transparent (even air is not, and a vacuum may be inert, but it does not transmit sound, most probably a massive block of metal will be the best, but there is no room for a listener in there).

My conclusion is, we need not to improve the items in between (in the sense that we are trying to make them pass the original, that will be impossible), we just need to make them sound as we like, and that will be different for each person. Or, as the ATL guys say, improvement is futile

Yes.. shunts can surely sound more detailed and dynamic than batteries.

Sorry for the off topic but I could not help myself: Synergy Aircraft

Sure Frans. On the other hand i plan a meeting of us and then you can listen to my system. I think it is up to the task of differentiating phono stages.
