IME, you’re better off keeping 2-ch and home theater separate. Can it work, sure but the end results can be very mid-fi on either side. If you’re striving for ultimate performance in both arenas, keep them apart. Been there, done that with ARC / Modwright on 2 ch and Classe Delta Series / Krell Evolution Processor and Amps on HT - 7.2 driving all B&W 800D2/HTM/804D/SCMS/JL Audio f212v2.
