Hi-Fi: The History of High-End Audio Design, by Gideon Schwartz, Phaidon Press, 2019. 272pp. $84.97, hard cover.

The ongoing evolution of hi-fi can be measured in any number of ways. Most obviously, we see that evolution in the technologies associated with our industry: in big breakthroughs—mono to stereo, tubes to transistors, analog to digital—as well as incremental improvements in materials and manufacturing techniques.

This, our February issue, is the first Stereophile issue to arrive during the year 2020, which marks the 50th anniversary of the founding of Audio Research—in my view one of the key events in the history of high-end audio. So it makes sense for this issue to include an Audio Research review—in this case, of the $20,000 Reference 160 S stereo amplifier.

My first exposure to current-mode phono preamplification was maybe a dozen years ago, when such products were new. The one I received, though nicely packaged, was not ready for prime time. I never smelled smoke, but I never heard sound, either: If it wasn't DOA, it was at a minimum DSAA—Dead Soon After Arrival.

At the October 2019 Audio Engineering Society convention in New York, Yuki Fukuda and Shunsuke Ishimitsu, both of Hiroshima City University, presented results that show quite clearly that listeners can distinguish sounds encoded and reproduced at different sampling frequencies. Their trials differed from the previous ones in one important way: Instead of exposing test subjects to music at different resolutions, they used test tones.

My in-person introduction to Devialet's products was under auspicious circumstances. I was in Paris for what would be a month-long vacation; my wife was there to give some lectures, but I was free to roam the city, take pictures, practice my bad French, and enjoy the excellent food—the experience of a lifetime except that, a few days in, I was missing music. Still early in my visit, I wandered by the big Devialet retail store near the Paris Opera; it was closed but it gave me an idea. I soon had two Gold Phantom powered loudspeakers in our Paris studio apartment.

Scotland's Fyne Audio already has a large lineup of loudspeakers, from small budget standmounts to some serious high-end contenders, like the nominally 96dB/2.83V/m, 8 ohm flagship F1-12, with its 12" concentric driver. I counted 23 models in 5 series, including four subwoofers but not counting their in-wall and in-ceiling lineup.

Should you ground your loudspeakers? With most speakers it's a moot point, since there's no practical way to ground the internal metal parts. A few companies—Tannoy comes to mind—have in the past sold speakers with a grounding pin, claiming reduction of distortion and RF interference.
