I think the formats are all supported natively, so I assumed that they are played using native macOS decoders etc., not something in Chrome.

Fun fact: I started using HQPlayer, which does upsampling so that whichever DAC you use it doesn't have to, with its limit power compared to for example the M1. It really makes a surprisingly big difference!

Do you play your own files or did you get it to work with Apple Music? If the latter, how?
