With my equipment - Sennheiser HD700, Centrance HiFi-M8 and an iPhone 5s I am more than happy with the sound quality of Apple Music. When listening to Spotify I can hear a minimal difference where Apple sounds better. That is the paid Spotify. Cancelled my subscription with them. Used to have 1411-7866 bps songs on my old iPod Classic but selling that now. The sound quality is enough now in Apples Music. Compared several songs that I had in my library lossless and then deleted them and listened on Apples 256 version and I can not really hear any difference. Maybe I am getting old ;-). The only negative is when I listen to Apple Music in my Bluetooth Headphones, some disturbance between Jlab Epic and my iPhone 5s from time to time. But not often. Using the D/A converter in the HiFi-M8 works perfect for me. Like Apples Eco-system. Now it is almost complete. Waiting for an app for the AppleTV as well.
