At Home:

• FLACs via mpd with a topping headphone amp and Audeze LCD2C headphones
• Vinyl using an Audio Technica LP120, a Denon AV receiver and cheap wharfedale bookshelf speakers and a Klipsch subwoofer. That Setup isn't really audiophile tbh, especially because the room sounds terrible.
• Streaming via Qobuz on both systems

On the go:

• Everything encoded as Opus 128 kbit/s to fit on my phone. Played over Lypertek Tevy true wireless IEMs. Not really audiophile but tbh when I'm not at home I care much more about convenience as long as the audio quality is good enough.
• also Qobuz, but at MP3 320 quality to save bandwidth

I wrote my own scripts to tag the music and encode it to FLAC and Opus and use syncthing to copy the files to my phone. So whenever I add an album to the library it will be available every where I want in the specified format without any manual copying involved. It's a little janky but has worked surprisingly well for years.
