My experience is all the services make it harder than it needs to be figure out which recording you are listening too. Start with the same recording, ensure you are bit perfect, no volume control in the app or automatic controls, and Apple, Qoboz, Amazon HD will sound the same. Tried Tidal. Sometimes it sounded exactly the same. Sometimes it did not. I assume that was whatever processing they are doing.
Apple Music vs Tidal for SQ
I compared Tidal to Apple music for the first time using speakers, not headphones. Apple seems bright and a bit less smooth the tidal on my system. I never tried the apple codec before but so far not a fan, it seems to have treble that is a bit fatiguing. What is your experience?
