this is a hard call, anthem is good gear, quite well made, and arc room correction can be very impactful in some (actually many) rooms in terms of improving sound quality that is heard
that said, pass labs would sound a little nicer, warmer, less overtly solid state-ish, is built even better, but they simply don’t do room correction
if your room benefits from room correction the sonic impact of that would greatly outweigh the slightly better sound of the pass without arc, i would think...
