I stream most of my music from Tidal, yet I do use Spotify as the playlists are terrific and Apple Music as my sizable library integrates well with iTunes

This is more of a semi-skilled layman's review, yet an audiophile, because I don't believe you have to be a technician to love great sounding music or even to be an audiophile

The music just sounds incredibly good

The Clears take all the elements into account and sound right and the music sounds great

The Clear’s just create a beautiful sound that is true and balanced.

but it is not essential with the Clear’s.

Just about any device can power the Clear’s but a headphone amp makes them shine.
