With the atomization of the playback of digital files into storage, servers, streamers, format converters, and DACs, I find that I've accumulated many miniature power supplies: small pods and wall warts. Most of these are generic switching devices made by companies other than the manufacturers of the components they power, and even those not designed for audio systems are, of necessity, at least adequate for the task. Because many of these supplies are indistinguishable from each other, I've taken to labeling them with sticky notes to remind me which goes with which component. Nonetheless, I'm concerned that they're no more than the commodity power modules available for a few bucks each on eBay. Whenever I think of the four or five of them clustered behind my equipment rack, I begin to suspect them of plotting revolt against the fancy gear they serve.

No one likes to be fooled, least of all those of us whose job it is to sort the real from the imagined: a tightrope walk, the audience for which reliably contains one or two rustics who delight in the occasional splat.

Such were my concerns in the days following last November's New York Audio Show, where I first encountered High Fidelity Cables—an exhibitor that generated considerable (figurative) buzz by promoting the use of magnets in an audio system's interconnects, speaker cables, and power cords. Indeed, by the end of the first day, more than one showgoer had asked me, "What did you think of the guy with the magnetic cables?"

In Lost Highway, published soon after he was introduced to Sam Phillips, in 1979, Peter Guralnick said he had long dreamed of meeting the Sun Records founder, who produced the hits that introduced Elvis Presley and other pioneering rock'n'roll performers. He dedicated Lost Highway to Phillips and the blues singer Howlin' Wolf, calling them "the real heroes" of the musical genre, and a quarter-century relationship between Guralnick and Phillips followed. This long, densely detailed biography is its affectionate culmination.

As part of his preparation for reviewing Merging Technologies' NADAC Multichannel-8 networked D/A processor in the March 2016 issue of Stereophile, Kal Rubinson talked with the Swiss company's Dominique Brulhart.
