MQA on Tidal and HR on Qobuz: Kings of the Streaming Hill

Last time we introduced our Greater Boston, MA readers to the high-resolution audio streaming services, Tidal and Qobuz. Both offer their subscribers the opportunity to choose exactly what they want to hear and hear it in full CD resolution...or better, selecting from vast libraries of recorded music. In this way they are distinguished from services like Pandora (adaptive playlists, not on-demand, and lower quality) and Spotify (on-demand, but not full resolution). Other full resolution services include Deezer and Amazon HD, but neither offers higher than CD resolution listening choices.
