Those of us who groan at the appearance of every new five-figure digital source component in a massively oversized chassis—and who groan in greater torment when the offending manufacturer says his customer base insists on products that are styled and built and priced that way—can take heart: The appearance of such sanely sized and affordable products as the Halide Design DAC HD ($495) and the AudioQuest DragonFly ($249) would suggest that the market has a mind of its own.

No one ever had to pay for recorded music—it was always "free" on the radio—and the home taping of LPs, the copying of cassettes, and, later, burning CDs made buying music optional. Then Napster and other file-sharing sites kicked it up a notch and made it very easy to assemble a 10,000-song collection without spending a dime. Now, Spotify, BitTorrent, SoundCloud, MOG, and YouTube make music instantly accessible on demand. It raises the question: Will music lovers continue to buy music? Paying for recorded music is now, more than ever, a voluntary act.

If there's a word that describes the feeling, the vibe present throughout Jazz in the New Harmonic, it's trance. Pianist and session leader David Chesky even uses it without prompting when asked how, among all his music endeavors—an album of difficult non–Joplin-like New York Rags in 2012, a children's ballet later this year, not to mention running Chesky Records—he found the time or inspiration to make a straight-ahead jazz record.
