It is said that while any competent engineer can design a superb loudspeaker if allowed an unlimited bill of materials, the true test is being able to produce a great-sounding, budget-priced speaker out of parts that cost a mere handful of dollars. With PSB's Alpha series of bookshelf speakers, Canadian engineer Paul Barton has illustrated this truism many times over the years.

Seen from the air, Denmark is a vista of farms and wind turbines. But once your plane touches down, it is a land of loudspeakers. Perhaps this is because audio has a long history in Denmark—it was a Dane, Valdemar Poulsen, who developed a magnetic wire recorder in 1898—but there are more loudspeaker manufacturers per person than any other country. According to Wikipedia, Denmark is home to 5.75 million people, compared with New York's five boroughs, which have a population of 8.67 million However, as well as drive-unit manufacturers Audio Technology, Peerless, Vifa (which merged with Peerless to form Danish Sound Technology), and ScanSpeak, there are Bang & Olufsen, DALI, Dynaudio, Gamut, Gryphon, Jamo, Lyngdorf Audio, Peak-Consult, and Raidho all making loudspeakers. Lots of loudpeakers.

PS Audio's Paul McGowan has been sending out a daily newsletter by email since 2011. In his May 29, 2019 epistle he asked, "What would our world of high-end audio look like if there were only active wireless loudspeakers? If even the half-a-million-dollar mega-beasts were internally amplified and connected via wireless and controlled from an iPad? No more boxes. No more wires and cables. Only speakers."

Apple may not have been the first to market with a portable digital audio player, but its original iPod defined the genre: a device small enough to fit into a shirt pocket. When companies like Acoustic Research, Astell&Kern, Fiio, HiFiMan, and Questyle introduced portable players that could play high-resolution files, they echoed the iPod's form factor. The exception was the Toblerone-shaped PonoPlayer, but even that was small. The subject of this review is another exception: The DMP-Z1, from Sony's Signature Series, is comparatively enormous—almost the size and weight of a regular preamplifier. At $8500, it's also considerably more expensive than other players.

I have reviewed several network-connected music servers in recent years, from Antipodes, Aurender, and NAD. All performed well but are relatively expensive, and their associated player apps didn't equal Roon's user friendliness in terms of interface, organization of the library, and inclusion and updating of metadata. So when Roon Labs introduced their own server, the Nucleus+, I first reviewed and then purchased it, along with a lifetime subscription to Roon. But at $2498 without an internal drive for storing music files, the Nucleus+ is still relatively expensive, and even Roon's less-powerful Nucleus costs $1398. I was still on the lookout for a server that would be more accessible to our budget-minded readers.

The good-sounding products that pass through a reviewer's system fall into three categories: those he liked but felt little sense of loss about when they were sent back to the manufacturer or distributor; those he loved and could afford to purchase; and those he loved but that were financially out of reach. The Rossini Player from British company dCS, which I reviewed along with the Rossini Clock in our December 2016 issue, was an example of this last category: the Player costs $28,499, the Clock $7499.

When we launched Stereophile's website at the end of 1997, we decided that we would not reprint the magazine's most popular features, including the biannual "Recommended Components" listings and Michael Fremer's monthly "Analog Corner" column. We were concerned that doing so would cannibalize magazine sales. As it turned out, we were wrong—and so the latest "Recommended Components" is available on our free-access website day-and-date with the publication of the April and October issues in which it appears. And starting with Mikey's very first "Analog Corner," from July 1995, I have been posting his column on our AnalogPlanet.com website.
