> Are you using a sound bar or speakers? Modern televisions have awful speakers

They’re honestly not, not on a TV larger than 40” and made in the last ten years (they’re using the same computational audio correction that’s in laptops now) and no reciever at any price point can fix a bad mix or a mumbling actor.

It’s the mixes and the actors that are bad. Your 400W reciever isn’t going to make “naturalistic” mumbling intelligible or fix fight scenes lit by tea candles, it’s just going to make your neighbors one floor down hate your fucking guts.
