> I can't hear the TV, which of these three remotes do I need to push the "source" button on?
I have a fairly dumb amplifier (it does BT, and the DAC can be fed through optical and coax, too). It can also be controlled over RS-232 and Ethernet. It doesn't have any kind of HDMI or other "home theater" related functions.
But the remote of my Fire TV can be configured to control the input and the volume of this amp. So if all I want is to watch a movie or something, I only need to reach for the amp's remote to turn it off when I'm done. If I'm too lazy, it can go to standby on its own if it doesn't get any input for a while.
I do agree, though, that a "normal person" would probably not want it. It's quite big and not particularly pretty. Plus it's useless on its own, you need some kind of source to feed it. A soundbar or some active speakers would be best for them, and it's what they usually choose.
