Of all the products I've reviewed or auditioned, a select few jump out as "best buy" recommendations. Almost universally, such products are liked by a wide range of audiophiles, and seem to match well sonically to many systems. Moreover, these products all have outstanding value; they offer a higher level of musical performance than you'd expect from the price.

"We like to make things," Roy Gandy, Rega's founder and owner, once told me. "It's what we do." Or maybe it was Rega's chairman and chief engineering honcho, Terry Bateman. Rega products are designed and manufactured in the south of England. So far as I know, no one at the Rega facility, on the Temple Farm Industrial Estate, has committed suicide; the same cannot be said of workers at the factory in China where iPods are made. Al Gore is on the board of Apple. Al, what do you think?

I've spent the last month recording songs for a pal's upcoming album. His act consists of powerful female and male singers, acoustic and electric bass, and acoustic guitars and mandolin. Jay-Z is funding the project, which is destined to transform the entire hip-hop/rap beat-driven pop landscape into an acoustic-music wonderland.

Okay, I jest about that last part.

The dual subwoofers were bumping and our pant legs were flapping. Only moments before, we'd been treated to a polite viola da gamba. Not now. Resolution Audio's designer, Jeff Kalt, had brought only two discs with him to ensure that his company's Cantata Music Center was functioning properly in my system: Jordi Savall and Hespérion XXI's Altre Follie, 1500–1750 (CD, Alia Vox 9844), and Tool's 10,000 Days (CD, Tool Dissectional/Volcano 81991). After changing a few things around with the chamber music, we'd advanced to the hard rock of Tool.

Late last year came an epic audiophile moment: I slapped a final length of tape on the box of the awesome-sounding MSB Diamond DAC (Stereophile, October 2012), in final preparation for its trek to John Atkinson's testing lab, in Brooklyn. Next up was the Bifrost DAC from Schiit Audio. I popped it into my system, where, moments before, the MSB had held court.

From $43,325 to $449. Yowseh!!—the MSB costs almost 100 times as much as the Schiit! Was this even fair?

Right now, I swear, Schiit Audio's Mike Moffat and Jason Stoddard are sitting there in California, smugly smirking at me and John Atkinson. While JA was struggling to properly measure Schiit's Ragnarok (Fate of the Gods) integrated amplifier for my review in the May 2016 issue, I sent Moffat an e-mail: "Are you smiling?"

"Yup," he replied. He'd known in advance that the Ragnarok wouldn't look good on standard tests. But he hadn't warned us: The Ragnarok's output-stage bias program responds to music sources, not signal generators.

In the early 1980s, when CDs began trickling out of the few existing pressing plants, they were such rare and exotic objects that Aaron's Records, on Melrose Avenue in Los Angeles, kept them secured under lock and key in a tall glass cabinet. A customer forsaking vinyl would enter the store and, with great fanfare, announce the decision by dropping a load of LPs on the front counter with a disgusted thud. Then, in a ceremony resembling a rabbi removing the sacred scrolls of the Torah from the ark, the customer would approach the glass cabinet. An employee would unlock and swing open the doors, and, under that watchful gaze, the customer would choose from among a scattering of titles, carefully avoiding any disc that did not include the Strictly Kosher mark of "DDD."

As readers of the Stereophile eNewsletter will be aware, the twin subjects of distributing music around my home and integrating my iTunes library of recordings into my high-end system have occupied much of my attention the past year. I bought an inexpensive Mac mini to use as a music server, using an Airport Express as a WiFi hub, which worked quite well, but my big step forward was getting a Squeezebox. I described this slim device in the mid-March and mid-April eNewsletters; I urge readers to read those reports to get the full background on this impressive device. In addition, the forums and Wiki pages on the Slim Devices website offer a wealth of information on getting the most from a Squeezebox.

I feel privileged to have followed the remarkable evolution of digital processors over the past four-and-a-half years. Since my first digital review—a survey of three modified CD players back in August 1989—I've been fascinated by the developments that have inexorably improved the quality of digitally reproduced music.

Perhaps I shouldn't have been surprised when I first spied the prototypes for Sonic Frontiers' luscious new digital combo, the Transport 3 CD transport and Processor 3 D/A processor, at HI-FI '97 in San Francisco. After all, this is the company whose meteoric rise from an electronic parts-supply outfit run out of president Chris Johnson's basement, to a large factory pumping out an impressive array of entry-level to crème de la crème tube electronic components, has elevated Sonic Frontiers to front-line status among high-end manufacturers.

Don't get the wrong idea. I don't watch trash TV. I am not interested in the doings of people who are famous merely for being famous. I was probably the last to realize that Paris Hilton was not the name of a French hotel. But the kitchen TV just happened be tuned to Channel 4 when I switched it on while I was preparing dinner. No, I do not watch NBC's Extra, but as I was reaching for the remote I was stopped in my tracks by what I saw. The show was doing a segment on the new L.A. home of Jessica Aguilera, or Christina Simpson, or . . . well, it doesn't matter. What does matter was the host's mention of all the cool stuff the bimbette had had installed in her new pied-à-terre: "...and a Sonos audio system, of course."

Spectral is a bit of an enigma in the high-end audio world. Although nearly 20 years old and one of the founders of the American high-end audio industry, Spectral isn't a name that comes quickly to mind when considering the best of the best in high-end.

Spectral's low profile is of their own choosing. They advertise very little, their products are demonstrated in a small number of stores, they almost never send products to magazines for review, and they are very quiet about their accomplishments.

Making digital audio sound good appears to be a much more difficult job than its developers first realized. When digital audio was in its infancy, there was a tendency to think that digital either worked perfectly, or didn't work at all. This belief led the engineering community to devise ill-considered and flawed standards that affect the musical quality of digitally reproduced music today.

The $799 Theorem was originally shown at the 1992 WCES in a very small chassis that prohibited adding features or upgrades. Sumo has since become more ambitious, putting the Theorem in a full-sized chassis and offering several upgrade options that would have been impossible in the truncated version.
