While ubiquity is not necessarily synonymous with high quality, the fact that Aurender's music servers/streamers appeared in at least 12 exhibit rooms at AXPONA 2017 certainly indicates that they're doing something right. In fact, in the third-floor room in which Aurender partnered with GamuT and Grand Prix Audio, their A10 caching music server and player with analog outputs ($5500) was the crucial source of excellent sound.

My second-day new-product coverage began with a visit to the Playback Designs room, manned by the company's president and designer, DSD champion Andreas Koch. There, I found two new Playback Designs products, the MPD-8 DAC ($22,000) and MPT-8 Digital Music Transport (target price $14,000-$20,000). Both are due out at year's end…

GamuT's designer and CEO, Benno Baun Meldgaard, was on hand in the first room I entered on Floor 4 to introduce the new optional R2R tape playback board ($1990) for the GamuT D3i dual-mono preamp ($8490). Whether the presence of a number of new and old tape decks at AXPONA—the one in this room was a rebuilt Studer—signals a rekindled interest in tape amongst anyone other than confirmed audiophiles is unclear. But what was clear is that the piano on Ben Webster's Gentle Ben sounded beautiful and mellow. The horn, in turn, was appropriately bright, and the presentation distinguished by a nice sense of depth.

The doors of the 2017 AXPONA—taking place this weekend at the Westin O'Hare in Rosemont, close to Chicago's O'Hare airport—had opened but 15 minutes when yours truly (far left) joined (L–R) Steve Guttenberg (The Audiophiliac blog for CNET.com/ Stereophile), panel moderator Chris Martens (Hi-Fi+), Conor Cawley (Tech.co), Steve Rochlin (Enjoythemusic.com), and an audience of at least 50–60 people to discuss "What does 2017 mean for audio?" I didn't know what to expect, or what to discuss besides the resurgence of vinyl and the promise of better sound through MQA. But thanks to excellent questions from Chris and attendees, and some truly stimulating contributions from my fellow panel members, I think some major ground was covered.

The biggest audio show in the United States, AXPONA (Audio Expo North America), takes place April 21–23 at the Westin O'Hare in Rosemont, close to Chicago O'Hare International airport. Since planting its roots in America's heartland just a few years back, the show has grown to offer, in 2017, at least 142 active exhibit rooms, 453 unique brands and exhibitors, an Ear Gear Expo so large that it has spilled over into surrounding hallways, and a full schedule of seminars and entertainment.

Ah, Carolyn Sampson. Ah, Mozart. Put both of you, along with the Great Mass in c and the marvelously tuneful early motet, Exsultate, jubilate, in the hands of Masaaki Suzuki and the period-instrument Bach Collegium Japan. Then, record it all in 24/96 for a BIS SACD, which you can download in its original format from multiple sites, and the results are pure pleasure.

New York-based Chesky Records has just announced its first two MQA-encoded CDs. On May 19, both Camille Thurman's new Inside the Moment and Rebecca Pidgeon's classic The Raven will hit the streets, as it were, with a list price of $18.98. Music lovers with MQA-enabled DACs will be able to experience the full benefits of MQA-encoding/unfolding, while others will enjoy Red Book quality sound.
