Choose between Simon Yorke S9 or transroto Zet1

You have to audition it or not consider it or take a risk. Those reviews may mean exactly nothing. Clearly, you want a very neutral, balanced sound with highest resolution possible. And the rest of your system should be up to the task, of course.
If my Nottingham Spacedeck does not lack highs and lows, I seriously doubt that Simon Yorke does.
I could suggest adding Brinkmann to your list.

Inna,

Thanks for your suggestion. I will check out the Brinkmann as well. However, all the turntables are setup with different cartridges and different systems. It's very hard to compare every turntable in the same or similar settings.

S9 + arm: solid, dynamic, punchy. Importantly, plug & play.

Brinkmann balance + 12arm: ethereally detailed, pleasant, "fast". Expensive

Transrotor "Fat bob" (the one that looks like a pressure cooker) + arm: Ferrari acceleration, good authority (close to the S9), solid.

Another to consider: Yorke's S10 with parallel arm. Better than all the of the above. (i.e., dynamics, solidity, details, speed, authority...)

Gregm, Have you heard the new Simon Yorke arm?

I have this stupid rule of mine. When it comes to turntables and I am in doubt I go for British not German or American. I could be wrong of course.
