Thiel loudspeakers are traditionally quite difficult loads for an amplifier to drive. The SCS2 is no exception, its impedance magnitude (the solid trace in fig.1) remaining below 5 ohms over almost the entire audio band. In addition, while the electrical phase angle (dotted trace) is low at almost all frequencies, it does become quite capacitive below 200Hz, which, combined with the low magnitude between 80Hz and 200Hz, will make high current demands on the partnering amplifier. The B-weighted voltage sensitivity is also only moderate at 85dB/2.83V/m, meaning that…

As I took my valedictory lap around High End, the immense audio show held each May in Munich, Germany, it was clear that this year's event was an exuberant flowering of mature technology. I witnessed the dominance of hardware for LP playback, as well as analog amplifiers, many of them based on tubes, and passive loudspeakers with traditional cone-and-dome drive-units. And there was no shortage of excellent and impressive musical demonstrations. Still, I experienced no revelations, and heard no announcements of any new technology that might trigger a hopeful anticipation of the near future.…
There are many other DACs to consider in that price range, and many readers will already have favorites. If so, the U-DIO8 is the way to maintain your sound quality and your preferred sound quality when making the move to multichannel. Nor is there any shortage of choices for those who can spend more.
Enter Mytek HiFi's Brooklyn DACs. My experience of using them for multichannel sound goes way back to Mytek's implementation of a similar scheme of stacking DACs originally based on a proprietary ASIO USB driver (footnote 5), and, more recently, based on the use of a "virtual audio device…
September 6 2018 marked the launch of Primephonic, which appears to be the world's most comprehensive classical music-streaming service. Currently available in the US, the UK, and its home base of the Netherlands via web and mobile applications—iPhone/iPad users can access it now, and Android users in October—Primephonic currently streams well over 1 million classical tracks from over 400 labels worldwide, including the three majors: Warner Classics (Erato, Virgin, Warner), Sony Classical (and Sony Masterworks), and Universal Music Group (including Decca, Deutsche Grammophon, Verve, and…
Our October 2018 issue features the latest "Recommended Components" listing, updated and revised. Want to know what we thought about more than 500 audio products? You will find the answers to that question inside this 196-page issue.
Featured on this issue's cover is Audio Research's awesome Reference 160M monoblock power amplifier, reviewed inside by Jason Victor Serinus. John Atkinson reviews the Australian Centaur II 500 amplifier; Herb Reichert, Legacy's Studio HD monitor; Michael Fremer, Sonus Faber's flagship Aida speaker; Kal Rubinson, Paradigm's hi-tech Persona 5F speaker; and Ken…
Other Minds, the San Francisco-based organization that champions music so far ahead of its time that the 21st century is still catching up with what OM championed in the last millennium, has turned its ear to archival works by unsung electronic music pioneers from the Bay Area and beyond. In its latest offering of digital-only Modern Hits releases, two of which are hi-rez (24/44.1), OM champions the music of Philip Bimstein, Tom Djll, Jerry Hunt, and Alden Jenks.
Even if you've never heard of these men, there's definitely something here for everyone. Universal in its appeal is Philip…

What ties Luciano Berio's boundary-breaking Sinfonia for Eight Voices and Orchestra (1968–69) to Pierre Boulez's out-there Notations I–IV for Orchestra (1945/1978) to Maurice Ravel's progressively off-kilter La Valse (1906–1920)?…
"No one's buying music anymore: They're renting it."—John Atkinson, keynote speech, AXPONA 2018
Streaming music isn't new. US companies have been doing it since the 1920s, when it was discovered that multiplexing—the then-new practice of combining multiple signals over a single conductor—could be used to send live or recorded music over public power lines. The first of those companies was Muzak LLC.
File that away.
