And stacked the profiles, so that you can now have both RoomFit and PEQ/EQ active at the same time.

Well yes but if you just use the same room correction profile with no EQ there shouldn't be any difference.

I don't think so. I just started to use RoomFit after the split, as I mostly use the EQ. Adding the RoomFit as a base for the EQ has actually enhanced the sound much more than I was expecting.

Yes, exactly. It's more than a little surprising. It's like my full range system got an injection of steroids. Everything is enhanced across the board. The vibrancy and separation is on another new level.

Extremely impressed here.

The Roomfit part of it is still the same as it was before the split. One way to compare would be to copy the Roomfit profile into PEQ and disable Roomfit. It should sound exactly the same.

The RoomFit change is really really really really confusing and annoying.

I’m glad for those who for whatever reason wanted EQs on top of their EQs so they can EQ while they EQ. But for someone who liked having all of their EQs in one menu like myself, this sucks ass. I know I can manually copy over RF/RC profiles but that’s a real shitty solution, huh.

I don't see the RoomFit as an EQ. It's a way to make your system sounding neutral and remove room issues, and then you can apply EQ/PEQ on top of that too match the music style or your mood.

It literally creates a PEQ.

Yes but for another purpose.
