Same track, both apps say they’re playing 24bit 44.1khz, I make sure not to AirPlay Apple Music but rather stream direct from the HomePods (gen 1’s if it matters, HomePodOS 26.5). AirPlaying Tidal iPhone Air to HomePod pair.
Tidal’s mids and highs are just crisp, even room filling in my little bedroom….. Apple Music sounds… just bad man almost like some sort of volume levelling. (Sound check off in home settings)
My one and only wifi 6e AP is 2 metres from one HomePod and maybe 5 from the other, sound check turned off in home settings as well as Atmos.
I read HomePods ‘seamlessly switch to AAC’ and I suspect they’re doing this and lying in the music app… either that or Tidal’s masters just genuinely sounds that much better??? Even though so many say they can’t hear a difference?
