Where is the info about compression, (and pseudo surround)?
I use all sources from my cable box/ethernet cable/Smart TV apps (no external streamer like Apple TV involved).
OFTEN, like broadcast the Voice; American Idol; YouTube ..... I change my AVR to 2 channel stereo, (or Direct which turns out to be 2 channel stereo), and it sounds better than whatever pseudo surround that is created somewhere _______? by somebody _____?
