Single unit solely for HT.
I have my separates for music.
Carver 4000t, sublime audio active crossover, Carver A760x (lows), Carver RAM285 (on order) mids/highs, Tekton Double Impact SE (bi amp, single berylium tweeter), Carver Silver Seven 900 to Magnepan 1.7i (maggies on order, eta, late May), 2x tekton 2-10 subs.
For HT I currently have 2014 Onkyo, klipsch theater speakers with with 2 self powered surrounds (not klipsch) on a klark technics wireless connection..
So yeah, only need a newer HT receiver solely for upgrading codecs and video out (8k, with upsampling for what can be).
Thank you.
