Anyone who thinks the high-end is on its last legs need only have passed the registration table for Rocky Mountain Audio Fest 20 minutes before the show officially opened. The lobby was mobbed, with the line literally going out the front door of the Marriott Denver Tech Center. Nor were these folks just from Colorado. On my first trip up the Tower elevator, I confirmed that my fellow passengers were audiophile visitors—not industry people—from Oregon and New Jersey.

Friday, October 10, 11:30am: the line to enter the 11th Rocky Mountain Audio Fest stretched into the Marriott Denver Tech Center's parking lot.

Friday night, I saw one of the finest, most intimate jazz sets I'd seen in a while: Ethan Iverson and Ron Carter playing duets at Mezzrow, a small new jazz club in Manhattan's West Village...

Among the biggest buzzes at the January 2013 Consumer Electronics Show, and at Munich's High End Show the following May, was the sound in the room of Siltech BV, a Dutch company best known for its high-end cables. Siltech was demonstrating an innovative new power amplifier, and using it to drive the company's glass-cabineted Arabesque loudspeakers ($90,000/pair). The sound was unmistakably lush yet also remarkably linear, notably dynamic, and seemingly free of electronic artifacts. It sounded like the sound of "nothing"—which was really something!—and so much of a something that it caught the attention of many reviewers. But while there's often controversy and disagreement about a given product's sound quality, this time the enthusiasm seemed unanimous.

"The Guitars of Rachel Rosenkrantz" is perhaps not quite as evocative a title as The Umbrellas of Cherbourg. Nevertheless, there are parallels. I met the young, French luthier through mutual friends, and was pleasantly surprised to learn that she is very serious about her art, and rather obsessive about her craft. Rosenkrantz studied art, architecture, and industrial design, and worked for some years designing commercial lighting fixtures and furniture. However, she let go of that career to start over from scratch as an apprentice to Daniel Collins, a builder of classical guitars. She recently opened her own custom shop, Atelier Rosenkrantz, in Pawtucket, Rhode Island, sharing space with jazz-guitar builder Matt d'Ambrosio.
