Components listed here have been formally reviewed in Stereophile and have been found to be among the best available in each of four or five quality classes. Whether a component is listed in Class A or Class E, we highly recommend its purchase.

Each listing-in alphabetical order within classes-is followed by a brief description of the product's sonic characteristics and a code indicating the Stereophile Volume and Issue in which that product's report appeared. Thus the May 2018 issue is indicated as "Vol.41 No.5."

The dichotomy between what is measured and what is heard has resurfaced in recent months. Jon Iverson discussed it in his "As We See It" in our December 2018 issue, and I followed up on the subject in my January 2019 "As We See It." These further thoughts were triggered by an e-mail exchange I had last December with Stereophile's longtime copyeditor, Richard Lehnert.

In 1967, the year the Byrds would fire him, David Crosby sits in a room—a small space, from the sound of it—with a cheap microphone and a recorder of dubious merit. He's improvising some jazzy, open-tuned acoustic guitar strumming, adding nonlexical vocables on top. He then files away the resulting tape—clearly ahead of its time and of no use to his bandmates—for 50 years.

Our 180-page April issue is hitting newsstands, mailboxes, and tablets this week and, as always with Stereophile's April issues, it includes the revised and updated edition of our "Recommended Components" feature—capsule reviews of the best-sounding gear available. And featured on the April issue's cover is Klipsch's RP-600M speaker, which features a horn-loaded tweeter. Read Herb Reichert's report to see how he felt about this little gem...

Given its engrossing, frequently radiant score, unflinching look at its timely subject matter, and superb cast of singing actors, Pentatone's live hi-rez recording of the premiere of Mason Bates and Mark Campbell's opera, The (R)evolution of Steve Jobs, fully deserves the Grammy recently bestowed upon it by the Recording Academy.
