Look into Schiit Audio! They're American designed and manufactured. Their receivers aren't as consumer friendly as those of sony/denon etc but the quality is amazing, they have low, mid, and high end devices for each category, and they dont have/require any wifi connectivity. I've been daily driving their headphone DAC and tube amp for the last 8 years with no problem.
Also why don’t TVs and AVRs use display port instead of hdmi (license costs)?
