Recently, I found myself in an email conversation with two colleagues on the nature of reproduced audio. How should we think about it? The conversation was provoked by a "hybrid" (live and online) presentation of the Pacific Northwest section of the Audio Engineering Society called "What Does 'Accurate' Even Mean?" The presenter was James D. "JJ" Johnston, a distinguished researcher in the field of perceptual audio coding and a co-inventor of MP3.
Among many other honors, Johnston was selected to present the Richard Heyser Memorial Lecture at the 2012 AES conventionan honor shared by our own John Atkinson, who had given that lecture the previous year and was one of the participants in this email conversation. The other was Tom Fineso, it was me and two sound engineers.

I recently received a letter (not yet published) suggesting a need for a glossary of newer hi-fi terms. Some audiophiles raised on physical media, it seems, are perplexed by descriptions of the new streaming landscape. Just yesterday, all we had to worry about was DACs and transports. Today we have servers, streamers, players, streaming DACs, and all that. That immediately struck me as a good idea, allied with a second reason: To avoid confusion, it makes sense for the industry to standardize the nomenclature. When we see the word "streamer," for example, we should all be thinking about the same thing.
So, here's a brief glossary of streaming-related devices.
Dear audio show exhibitors: This one's for you. As members of the press who have spent decades covering audio shows, we've developed a clear sense of what works for us andwe thinkfor other show attendees. We ask your indulgence as we share our observations about how to mount a successful exhibit and get the best coverage possible from Stereophile and, presumably, other publications.
This is an album with serious audiophile cred. It was recorded to analog tape on a Studer A800 MKIII at 30ips, by Ryan Streber at Oktaven Audio in Mount Vernon, New York. It was mixed, also at 30ips, on a custom, tubed Ampex 351, by Pete Rende. Bernie Grundman mastered it for vinyl and cut the lacquer, direct from the analog tape, on an all-tube system. The executive producer for the vinyl version is Hervé Delétraz of darTZeel, who, Sabbagh told me, helped finance the mastering and pressing. Sabbagh listened to the acetates and test pressings at Ana Might Sound in Paris.
On this page in Stereophile's December 2023 issue, contributing editor (and mastering engineer) Tom Fine and I described a press event at which Apple Corps (the Beatles umbrella corporation) presented the news about the (at the time) forthcoming new Beatles single and the forthcoming "remixed" reissues of the "Red" and "Blue" Beatles compilations. Tom attended the eventwhich, notably, was held at Dolby headquarters here in New York City, reflecting, apparently, Apple Corps' interest in Dolby Atmos. At the event, demos were presented in the Atmos format onlyno stereo.
A key point of that column was that Apple Corps, at leastand who knows how many others in the music industryare abandoning high-quality Atmos in favor of that streamed by Apple Music. Tom and I criticized this development in no uncertain terms, concluding that if Apple's lossy-compressed version of Dolby Atmos is what we're being offered, "we should hope for its demise."
When I was offered the opportunity to review a Burmester productthe 216 stereo power amplifierI accepted immediately, mainly out of curiosity. Berlin-based Burmester is an important hi-fi brand, but I knew very little about the company and their products. What better way to learn more than to review one of their products?
In the midst of his December 2023 Gramophone Dreams column, Herb Reichert presented the results of an experiment. He was listening to the most recent version of Zu Audio's Denon DL-103, installed on his new-old Lenco. He hooked it up to the moving coil input of his SunValley SV-EQ1616D phono preamp, which apparently is intended for use with low-output MC cartridges since it loads them down with a 50 ohm shunt resistora heavy load for all but the lowest-impedance MCs. The rough rule of thumb for loading an MC cartridge, as many readers are aware, is that the load resistance should exceed the cartridge's internal impedance by about a factor of 10.
On September 27, 2023, executives from Apple Corps and Universal Music Group held a press event at the Dolby Theater in Manhattan. The event included Dolby Atmos demos of forthcoming Beatles releases. It included some big newsalthough the biggest news wasn't obvious at first.

A few months ago, the hi-fi world learned that Audio Research, perhaps the most storied hi-fi brand in US history (McIntosh would be the other choice), had a new owner. The company had overextended itself, then filed for "Assignment for the Benefit of Creditors"somewhat like Chapter 11 bankruptcy but different. The company was then acquired by a group led by a Canadian, Valerio Cora of Acora Acoustics. In the September issue's Industry Update, I wrote, "Audio Research, that great American hi-fi company, is now Canadian."
Not long after the issue came out, I received a note from Dave Gordon of Audio Research Corporation. With typical good humor, Dave suggested that my characterization was not correctthat ARC is not in fact Canadian. Why? Because Audio Research's parent company is based in ... Delaware?
It's an error commonly made in evaluating hi-fisystem performance: the failure to listen differentially. Differential as in compared to something else. "Something else" could be a different recording on the same system or (especially this) the same recording on a different system. The question is, what are you comparing it to? The point is: Do you really know what that recording sounds like?
