PlexAmp is an amazing bit of software for a phone. It doesn’t translate well to the desktop, but it’s still pretty good.
Your flacs will play lossless on wifi, and transcode to 128kbps opus on mobile. You can tweak those settings too.
Most smart TVs have a native plex app available too.
I was tempted by Arc. Intel drivers always “just worked”, but they are just slow. Arc didn’t address the problem like I’d hoped, and AMD really got their shit together in the last 5 years or so.
