As audiophile as I am (own very expensive (> 1k) headphones for instance) and additionally I’m musician/producer.

I don’t think you can hear the difference between 320kbit bitrate vs flac in a blindtest (this is important, to avoid biasing yourself). I could notice what was a 128kbit mp3 and flac in a blindtest and already that was minimal (and is likely mostly related to the 16k cut-off of 128kbit mp3), but 320kbit, nope…

If you notice a difference it likely has to do with different mastering/LUFS etc. not the compression artifacts themself.

I recommend ad-blockers (ublock origin), I haven’t seen ads in like years on my devices.
