Schiit Audio Bifrost D/A processor

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?

Schiit Audio Yggdrasil D/A processor

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.

SigTech TF 1120 Time Field Acoustic Correction System

Imagine an electronic magic wand you could wave at your listening room's acoustical problems to make them disappear. The Cambridge Signal Technologies SigTech TF 1120 may be just such an alchemical device. Its efficacy depends on the nature of the acoustical warts in your listening environment. Operating solely within the digital domain, the SigTech device can perform both drastic and subtle frequency-response and time-domain corrections that are beyond the scope of analog-based units. While the TF 1120 is expensive, in some situations it may still be the most cost-effective way of coping with acoustical gremlins. Is it the solution to your problems? Perhaps.

Simaudio Moon Evolution 650D CD player

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."

Slim Devices Squeezebox WiFi D/A processor

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">http://www.stereophile.com/digitalprocessors/505apple">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-Marchhttp://www.stereophile.com/images/newsletter/306Bstph.html">mid-March; and mid-Aprilhttp://www.stereophile.com/images/newsletter/406Bstph.html">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">http://www.slimdevices.com/dev_overview.html">Slim Devices website offer a wealth of information on getting the most from a Squeezebox.

Sonic Frontiers Transport 3 CD transport & Processor 3 D/A processor

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.

Sonnet Morpheus D/A processor

Playlists embody who we are. We use musical affinities to understand (or at least categorize) others, not only as evidence of their aesthetic discernment but also of their emotional and political affiliations, which amount to an entire worldview. In other words, the database of favorite music that we carry around in our brains is no laughing matter. So, one of the most unexpected—and rewarding—things that can happen in music fandom is a complete and sudden inversion of one's beliefs. Which brings me to the perennially touchy subject of Steely Dan, a band that cleaves the ranks of listeners like a gold-plated katana.

Sonos ZP80 & ZP100 WiFi Music System

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."
