I've really tried to convince myself that Apple Music's sound quality is adequate since it's the most seamless streaming service but I can hear a difference on the music I'm most familiar with between a lossless copy ripped from a CD (or from Tidal hi-fi) and the version on Apple Music. On one hand I am an audiophile and do spend my money on a audiophile gear and opted for the Harman Kardon sound system (while I realize I may notice the difference more so on a pair of headphones as some audiophiles consider even high-end factory car audio systems to provide average sound ) in my vehicle so I can appreciate the difference. On the other hand, the majority of listeners are totally ok with even lower quality than Apple Music, or listening with EarPods. But once you go lossless you don't go back. It's the drum beat hitting harder and sounding more detailed, it's the guitar having a newfound fullness to it, it's a treble that's crystal-clear and well-seperated, it's vocals coming through with the clarity of the lead singer being in the room with you as it feels like you're surrounded by a live band. Jay-Z and Tidal aren't wrong by stating that lossless is more about the emotion: you get all the sound frequencies rather than a compressed experience, it simply feels better. My theory has been that Apple is waiting to introduce a lossless music option as a way to to tout a benefit to the removal of the headphone port, so I can wait till September but I could very well switch back to Tidal and pay double just to enjoy my music. Once you go lossless on a quality pair of headphones or a high-end sound system, songs just won't feel the same compressed.
