A Yamaha RX-V4A is $400 and the RX-V line goes up from there.

(Yes, I like Yamaha audio equipment.)

I like Yamaha, I have an older one in my living room, but for the $550 (local price) I am not extatic of what it offers. The digital part is a joke, it has a DAC in it but I cannot use a laptop as a digital source over USB, it has an Ethernet port, but it cannot use it for an embedded management web site, you need to run a phone app for that. My $15 relay controlling the lights has WiFi and embedded management web site, a $550 AV received does not. Also you cannot play movies, only music, even if it has in it what it takes for that. Figured out why?

And this is not Yamaha, everyone is selling the same stuff. You can find cheaper Chinese integrated DAC + amplifiers, WiFi and BT with more modern stuff in it. Yes, the amp part is much lower quality, but you need features, convenience, great user experience, not just good audio. At least with the cheap soundbar you don't have high expectations, no disappointments.
