At 1:00 on Friday I spoke with Sarah Tremblay (above), co-organizer (with Michel Plante) of the Montreal Audio Fest. The 2019 show had opened only two hours before we ran into one another, and already over 4600 attendees had pre-registered and 1400 of them had arrived on-site. (Admission is free, but the organizers ask of each attendee their name and gender, and whether they'd attended previous Montreal shows.) Tremblay told me that approximately 50% of registrants so far were first-timers: an excellent sign.

According to the 2018 edition of the UN's World Happiness Report, Denmark is the third-happiest nation on Earth, trailing only its neighbors Finland and Norway.

I heard that yesterday afternoon, on NPR. The reporter even spelled out the word used by Danes to describe their feelings of happiness: hygge. Apparently, at present, Denmark is positively rotten with hygge.

To audio designers in Japan and elsewhere, the single-ended, 300B-tubed amplifier is like a haiku: an art form defined by both its prescribed limitations and the potential such restraint offers for artistic expression. Here, the only hard-and-fast rule is a simple one: output devices are limited to one 300B directly heated triode tube per channel. From there, it's a blank slate: Do you want AC or DC on the output-tube heaters? Tube or solid-state rectification? Low or high gain? Fixed or cathode bias? New parts, vintage parts, or a mix of both? Triode or pentode tubes as drivers? Capacitors or transformers—or nothing at all—between the plates of the driver tubes and the grids of the output tubes?

There's no place for fashion in epidemiology, aeronautical engineering, or the mining and storage of uranium. Fortunately, domestic audio is less serious, its goals more scattered and ambiguous, than those and a thousand other pursuits.

And so, throughout the 20th century, any number of trends in domestic audio popped up their heads, some remembered as fads, others as legitimate approaches to playback. Among the latter are amplifiers whose output sections operate in single-ended mode, in which the entire signal waveform is amplified by a single device.
