TV audio
Our living room setup is comprised of a 75" Sony with eARC to KEF Wireless 2s augmented with a pair of KC62 subs. But the internal audio of the Sony TV is so good it rivals the external audio. I may reserve the external audio for Roon and Blue rays. I don’t recall TV audio being as good as it is with our new Sonys. The sound is detailed, the imaging precise, the LF robust.
