FTR, #atmos is utter garbage.
No, I don't care that you got conned into buying $2k of a shitty, plasticky, disposable system that added two extra channels, without a decent return/benefit for it.
"Atmos" is just (tldr) bouncing sound from the ceiling to simulate sound coming from above. Unless you are listening to the system in a room within the very, very narrow specs of ceiling height, material, etc, you just wasted bandwidth, materials (plastic, wood, wires, etc), and my patience. Even when configured to optimal specs, atmos sounds like dogshit.
#SurroundSound rules: K.I.S.S.
Can't beat *wired* speakers, connected to a decent, simple amp, A/V receivers are ok, see rule about amplifier.
90% of everything works with 5.1;
No, none of the "newer" codecs are better than DTS HD Master or Dolby TrueHD;
No, two subwoofers are not necessarily better than one;
Bluetooth is utter shit;
HDMI ARC is shit, and HDMI after 1.3 is about the same.
Korean companies never made anything audio that sounded remotely good or was not disposable crap;
PMPO rating is a scam;
More wattage does NOT mean better sound;
Louder doesn't mean better;
Brand cables are a scam;
Looks of a speaker don't mean shit for the sound;
More expensive doesn't mean better.
