Here's my setup - Cambridge Audio DacMagic, Monolith THX 887 Amp. When listening to lossless music from Apple Music from my iPhone, it works fine. But somehow switching it over to connect to my MacBook Pro, the sound is greatly distorted!? The odd thing is with this setup, playing a Music Video from iTunes or youtube, it sounds fine. The terrible distortion happens only when I play any songs from Apple Music. What could be the reason?! My MacBook Pro is running Mac OS Big Sur which supports Apple lossless. Anyone having similar problem?!
