Organelle M vs Original Organelle: Audio quality

I owned the Organelle M and an original Organelle for a while (sold the v1). I noticed that the audio conversion (line in) and outputs on the M sounded better and more dynamic. Was there a hardware change other than the move to Raspberry Pi on the audio side… or a change to the mother patch? I was surprised to hear the difference in the inputs and outputs. Maybe it is all in my head/ears, but I curious if others who have owned both noticed this.

I haven’t owned both but the compressor settings are different I think. This was discussed on another thread. However I’d also be curious if there was anything else different in the hardware - converters or anything else significant.
