The shaft of the mechanical rotary encoder has a click feeling when turned. Depending on the product you are using, the click feeling may vary, but it is a function required for the brush contacts to make correct contact with the electrodes in the specified position.
This means that a better quality encoder is installed in the A30.
I don't like the ratchet encoder in Topping, it feels like a very cheap device.
This DAC also uses a cheap LM4562 instead of the OPA1612 in the Pro V2.
