I am overall pro-DSP, but my experience with Anthem’s Room Correction is that it’s OK. I felt I did better when I EQ’d the room myself. One mistake I made, and for me it was a big one, I assumed Anthem’s ARC would let me use 100% custom EQ curves and that’s absolutely not the case.
On the other hand, for a system where you barely have to touch anything I can definitely see the appeal of ARC. I wish I had infinite funds and time to try Dirac as an alternative for instance.
