While stage size, transient clarity—and, especially, transient speed—were noted when I played my usual reference LPs recorded in concert at Carnegie Hall (Tony, Harry, the Weavers; footnote 2), it was two recordings of solo piano that demonstrated the Kai's dynamic and tracking abilities: Vol.1 of a series of direct-to-disc recordings of Beethoven's piano sonatas by Bernard Roberts (LP, Nimbus D/C 901; does anyone have a spare Vol.2 they'd care to send me?—footnote 3)—and John Lill performing works by Schumann on a restored 1964 Steinway: the Fantasy in C, Op.17; Faschingsschwank aus…

Editor's Note: This article is in part about depression and suicide. If you think of harming yourself, the National Suicide Hotline is there to help: 1-800-273-TALK.
When German writer Johann Wolfgang von Goethe published The Sorrows of Young Werther in 1774, he intended for readers to finish it, but not, you know, to end it. To Goethe's disbelief, his novel sparked a spate of suicides. The title character, whose obsessive love for a married woman was unrequited, ended up shooting himself, and soon the copycatting started. Young men of the era would dress just as the fictional Werther had…
Less than two weeks before the start of Munich High End 2024, I spent several days in Faro, Portugal (footnote 1), touring the modern 1000-square-meter headquarters and manufacturing facility of digital-audio company Innuos. My hosts were Amelia Santos, chief executive officer, and Nuno Vitorino, chief technology officer.
Amid late-night meals, sumptuous lunches, tours of 8th-century castles and 13th-century churches, and a romp on Cacela Velha beach, we focused on a company that, 15 years on from its founding by Vitorino and Santos, makes music servers and streamers, network…
The Internet of Things has arrived at the stereo rack (footnote 1). Many hi-fi systems are now connected to the wider world, controlled by phones and tablets. Complex front panels with many switches and buttons have practically vanished; those still around are retro pieces or style statements. Little front-panel touchscreens with complex menu trees have been rendered vestigial or at least redundant. Designers of receivers, integrated amplifiers, and DACs must now at least consider incorporating a streaming module and a device-control app. In certain component categories and certain price…
We interrupt this tech talk for music
Having unpacked the H400 from its sturdy double box, I set it up in my office and connected it to my Amphion One18 nearfield speakers. While I dug further into the guts of the H400 (in the virtual sense, not literally), I started playing music. Because the only network-connection option is wired Ethernet, connecting to my home network required no fussing with passwords. I downloaded the Hegel Connect app to my iPhone 15, and it quickly found the H400. From the Home screen, I had immediate access to Airable internet radio and podcasts, and via…

Sidebar 3: Measurements
I performed a full set of measurements on the Hegel H400 using my Audio Precision SYS2722 system. I used the front-panel controls, the remote control, and the Hegel Music Systems app, which I installed on my iPad mini after connecting the amplifier's Ethernet port to my network. Not all settings are available with the app. The amplifier is specified as having a maximum output power of 250W into 8 ohms; I preconditioned the H400 before the measurements by following the CEA's recommendation of running it at one-eighth of the full specified power into 8 ohms for 30…
To examine the H400's digital performance, I used the coaxial and optical S/DIF inputs—the optical input only accepted data sampled at rates up to 96kHz—and USB data sourced from my MacBook Pro. (While Roon recognized the Ethernet-connected H400, it reported that "Unfortunately, the manufacturer has not yet completed certification for use with Roon." Footnote 1) The USB Prober utility identified the H400 as "Hegel USB" from "Hegel Music Systems," with the serial number string "2 (none)," and indicated that the USB port operated in the optimal isochronous asynchronous mode. Apple's AudioMIDI…
