At the Los Angeles Audio Show, held June 2–4, John Atkinson spoke with Elac's Andrew Jones about speaker design, building affordable loudspeakers, and Elac's Adante AF-61 speaker, which made its debut at the show, driven by Audio Alchemy amplification.

Want to go from yang to ying by the simple switch of a silver disc? Try seguing from the two supremely energetic, densely populated chamber symphonies of Pulitzer Prize-winning composer John Adams (b. 1947), which we explored last week, to the far milder and less complicated choral work, Canticles of the Holy Wind (Cantaloupe) from the other Pulitzer Prize in Music-winning Adams, John Luther Adams (b. 1953).

In 2014, Chad Kassem, proprietor of Acoustic Sounds and Analogue Productions, released a 200-gram QRP vinyl pressing of Masterpieces by Ellington, one of the Duke's least-known but possibly finest and finest-sounding albums, to wild acclaim and (by audiophile standards) brisk sales. Now he's put it out at 45rpm, and while the 33 was a startler, the new version—spread out on two LPs, to accommodate the wider grooves—will leave you breathless.

The Dickinson brothers are traditionalists and modern proponents of the kind of music that was celebrated in American Epic.

Maybe you've seen the widely circulated New Yorker cartoon: Two guys stand in front of a nicely drawn, tubed audio system, under which are shelves full of LPs. One guy says, "The two things that really drew me to vinyl were the expense and the inconvenience."

If you can't laugh at that, you've lost your sense of humor—even acknowledging that, oddly, convenience is the raison d'etre of some recent phono preamplifiers—including Dan D'Agostino Audio's Momentum and the CH Precision P1, both of which offer multiple, switchable, configurable inputs saved in memory. Today's well-heeled vinyl enthusiast might have two or more tonearms mounted on a single turntable—or even two turntables, each with two arms. Zesto Audio's new Andros Téssera tubed phono preamplifier takes aim at that market segment.
