@rotarius I got the Ammonite collar and it is well built and works well. It only needs one set-screw as the internal shape of the cylinder grips the shaft on 2 other points. I did not notice any sonic change after fitting. VTA adjustments feel more precise.
Jelco SA-750D or Rega RB250
I'm looking for very specific advice. I'll list some key words, can you guys please tell me which arm matches them better? Between Jelco SA-750D and Rega RB250 (or variants such as RB251, RB202, RB220) Thanks for all of the help.
Bolder, bigger, wider soundstage, more pronounced midbass, more bass slam.
