The last room I visited before the Wes Phillips Memorial, which was hosted in the PS Audio room Friday night of the show, was conveniently, PS Audio's. In my photo, the company's cofounder, fitness freak Paul McGowan, whom his daily email newsletter has revealed to be a talented writer, poses beside the humongous collection of PS Audio gear that was used to drive the Scaena La Maitresse Ultime speakers ($125,000/pair).

As you can read elsewhere in our RMAF coverage, the incomplete remodeling of the Denver Tech Center Marriott mean that the CanJam exhibits had to be moved to a tent in the hotel parking lot and the seminars and Classic Album Sunday events were held in temporary housing "pods." I wandered into one of the latter to find Channel D's Rob Robinson (above) playing 24/192 rips of LPs on a system featuring a Lynx HiLo digital converter, a Jeff Rowland amplifier, Cardas cables, and Joseph Audio Pearl 3 speakers.

My beat at the 13th RMAF was the 7th and 11th floors of the Marriott Tower, so to kick off my reporting, my first room on the 7th floor was Dynaudio USA.

I have been an advocate of small speakers since I began using BBC LS3/5a's in the late 1970s, continuing through Celestion SL6es in 1981, Celestion SL600s and SL700s in the late '80s, and B&W Silver Signatures in the mid-'90s. Yes, I do like accurate and extended bass reproduction—but you need a big speaker to be able to provide that, and, as the late Spencer Hughes, founder of Spendor, once remarked, "big speakers have big problems." I don't see the point of extending a speaker's low-frequency performance if the result is compromised soundstaging and midrange reproduction. And there is also the intellectual elegance of a speaker that is no bigger than it need be.

Last June, Jim Austin briefly discussed the operation of MQA in his review of the Meridian Explorer2 USB DAC, but you can find a more detailed explanation on Stereophile's website here and here. MQA involves two fundamental concepts, discussed in a paper presented to the Audio Engineering Society in October 2014. The first is responsible for a large reduction in the bandwidth required to store and stream high-resolution files, the second for a potential improvement in sound quality. . .

I am a big believer in supporting events promoted by specialty audio retailers. They reinforce the idea that audiophiles and manufacturers—even reviewers—are parts of a vibrant community that believes that listening to music with the highest possible quality is one of the more important things in life. The "Music Matters" evenings arranged by Audio Advice in North Carolina, Definitive Audio in Seattle, and Listen Up in Colorado exemplify that idea, and it was in April 2015, at Listen Up's Denver store, that I used a pair of PSB's new Imagine T3 tower speakers to play the audience some of my own recordings. The T3 superficially resembles PSB's Synchrony One, a speaker I very favorably reviewed in April 2008, and I was equally impressed by the new flagship—impressed enough to request a pair for review.

Stax Kogyo, a small audio company by Japanese standards, has been for the past 15 years steadfastly refining and redefining the electrostatic headphone. The SR-Lambda Pro is their current flagship model, and at a 1984 US list price of $780 it also represents a very substantial investment in headphone technology.

I do quite a bit of headphone listening during the day, making use of their convenience to shut out the office hubbub while I get down to serious copy editing. The system I use is modest—a pair of no-longer-available Sennheiser HD420SLs driven by an Advent 300 receiver I bought for $75, with CD source provided by a Denon DCD-1500 II—but I get quite a bit of musical satisfaction from it.

Editor's Note: One-bit DAC chips in the 21st century, where the anlog output signal is reconstructed from a very high-rate stream of pulses, are ubiquitous. But a quarter-century ago, those chips were only just beginning to stream from the chip foundries. In this feature, we aggregate Stereophile's 1989 coverage of the then-new technology, starting with Peter van Willenswaard on the basics.—John Atkinson.

1989 may well become the year of the D/A converter (DAC). CD-player manufacturers have, almost without exception, launched research projects focusing on this problem area of digital audio; many of these projects are already a year old. This is, however, by no means the only imperfection keeping us away from the high-quality sound we have come to suspect is possible with digital audio media, and maybe not even the most important.

Life is too short to put up with poor-sounding headphones, I mused the other morning, during my 60-minute commute on the NYC subway. All around me, straphangers gripped smartphones and listened to multicolored Beats, noise-canceling Boses, white Apple earbuds, and, only rarely, Sennheisers and Grados.
