A recent post on Roon's forums drew my attention to an apparently new category at Apple Music, Apple's streaming service. The post pointed to an Apple Music page listing music curated by the ECM music label. After ECM "Playlists," "New and Noteworthy," and "Recent Releases" is a section labeled "High-Resolution Masters."

One of the better things about bookshelf loudspeakers is that they're innately portable. Though not generally considered the sort of music-reproduction machines you'd bring to a party, a 12-step group, or a Burning Man rave (though you certainly could), high-quality bookshelf speakers are overlooked tools in the eternal work-in-progress of introducing lovers, friends, and family to our beloved lifestyle. So during the first week or three of breaking in the Quad S-2 bookshelf speakers, I thought, Why keep these to myself? It's strict Stereophile policy that all gear be evaluated in the context of the reviewer's reference hi-fi rig(s), but there's no law against sharing the joy.
