Aurender was a name new to me when I encountered the company at the 2015 Consumer Electronics Show, where they displayed a range of music servers designed in California and manufactured in South Korea. But what caught my attention in Aurender's suite was their Flow portable D/A headphone amplifier ($1295). This handsome, battery-powered device, housed in a machined aluminum case about twice the size of a pack of playing cards, offers optical S/PDIF and USB 2.0/3.0 input ports and a single ¼" stereo headphone jack. Two features distinguish the Flow from the pack: Its USB input can be used with iOS (iPhone/iPad) and Android smartphone sources, and it can accept an mSATA drive (not included in price) of up to 1TB capacity for internal storage of audio files. Visually, the Flow's distinguishing feature is its round LCD display, which stands proud of the faceplate; the bezel encircling the display acts as a velocity-sensitive volume control operating in 0.5dB steps.

The Model 34 preamplifier is the component from English manufacturer Quad that will disenchant perfectionists, partly because of its obvious pandering to connoisseurs of old and sometimes lousy-sounding records, and partly because of its sound.

This solid-state design is supplied with a built-in moving-magnet cartridge preamplifier, and a moving-coil preamp is included with it for (easy) installation by the user if desired. (Remove two screws, pull out the old module, plug in the new one and replace the screws. The job takes about 3 minutes.) The MC preamp supplied is for 20 microvolt-output cartridges—contrary to the instruction booklet's statement that the supplied one is the 100µV version. Modules having a rated input level of 100 or 400µV are available as extra-cost options.

Herbie Hancock's 1965 quintet album Maiden Voyage holds a firm place as one of the great jazz records of that transformative decade, and a new vinyl edition on Music Matters Jazz—the LA-based house renowned for its audiophile LP reissues of Blue Note titles, and only Blue Note titles—sounds finer than it has on any pressing in 50 years.

Editor's Note: We are reprinting this 38 year-old "As We See It" essay because if you substitute the words "WiFi" and "cellphone" for "Citizen's Band" and "CB Radio," you will realize that not much has changed in the decades since, with our audio systems still awash in a bath of RFI.—John Atkinson

Although Citizen's Band radio may hold little interest for perfectionist audiophiles, there is a good chance that it may intrude upon our activities in some disastrous ways if we, and the audio industry in general, sit back and ignore what has been going on behind the scenes in Washington, DC.

It was with regret that I heard John Ulrick had passed away on May 20, 2015 due to complications from cancer. With Arnie Nudell and Cary Christie, John was one of the founders of loudspeaker manufacturer Infinity, a company that, with Audio Research, Magnepan, Mark Levinson, and Threshold, epitomized the nascent High End that emerged in the early 1970s. After leaving Infinity, John Ulrick started Spectron, to manufacture class-D amplifiers.

Just by chance, I met with the John Ulrick, in Los Angeles in late 1987, when he was doing some design consultancy on a switch-mode power amplifier to be used with the Sumo Samson subwoofer. As I had my Walkman Pro with me, I took the opportunity to tape some background from John about the birth of Infinity and about switching/pulse-width-modulated/class-D amplifiers—boy, can this man talk about switching amplifiers! The natural kickoff question was, How did Infinity get going?

Earlier this year I pried myself from my upstate-New York home long enough to visit Robert Lighton Audio: a beautifully decorated suite on the 12th floor of 37 West 20th Street in Manhattan's Chelsea district, in which an Audio Note Ongaku amplifier shares space with a Suzanne Guiguichon armoire, and from which the view of the Empire State Building is stunning.

For me, the highlights of any audio show are finding a room with great sound and visiting it often throughout the show, to relax and absorb a wide range of great music. At the NY Audio Show in April 2012 in New York City, it was the room occupied by the Valve Amplification Company. There, I fell in love with the sound coming through the Signature Mk IIa line-stage preamplifier, and remembered that while I'd heard many VAC products at audio shows over the past two decades, and had enjoyed the sound every time, I'd never had a VAC product in my house. I requested a review sample.

For decades, I read all the British and American audio magazines, and I pretty much believed everything written therein—with one exception. The equipment reviews published in Stereo Review had an off-puttingly disingenuous quality. I learned a lot from the magazine's reviews of recordings and loudspeakers, but every time senior editor Julian Hirsch wrote that any amp with sufficiently high power, low measured distortion, and high damping factor would sound the same as any other with similar qualifications, I felt estranged from my favorite hobby. Stereo Review's arrogance came off as duplicitous and self-serving. The magazine seemed committed to stamping out all forms of individualized audio connoisseurship.

"I don't know what I think on that one. I haven't written about it yet."—Walter Lippmann (attributed)

As sometimes happens, this started out to be a very different column. But by the time I was a thousand words into it, I found that my point of view had changed.

A number of months ago, I received from a Canadian company called BIS Audio a review sample of their Expression interconnect: a shielded, unbalanced interconnect terminated with Eichmann BulletPlugs (RCA). Priced at $480 Canadian per 1m pair, the Expression falls squarely in the middle of BIS's interconnect line: a lowish range for high-end audio, and suggestive of a manufacturer that values value.

The business of high-end audio can fascinate me almost as much as does high-end audio itself. Designers and entrepreneurs such as Frank McIntosh, Avery Fisher, Saul Marantz, Edgar Villchur (AR), David Hafler (Dynaco), and Henry Kloss (AR, KLH, Advent, Advent Video, Cambridge Soundworks, Tivoli Audio) combined technical brilliance and varying levels of business skill with flairs for publicity and marketing. Many of their products became objects of desire, and some became household names in the post-WWII era. Of that list, only McIntosh and Marantz are still in business as high-end audio companies—the latter relatively affordable, the former exclusive.
