The Nonesuch Records CD Steve Reich: Pulse / Quartet arrived with its sonic bonus unheralded. With no MQA designation on the album cover or disc, few would have known of its MQA provenance had not posts appeared on Facebook that, when inserted in a player capable of decoding MQA, it can deliver high-resolution MQA.

Audiophiles are oblivious to the low-end music-reproduction medium that's currently staging a comeback: the cassette tape (footnote 1). I've adopted the cassette craze in my own small way. I glory in the trusted mixtape, which I play in the stereo cassette deck of my 1990s Toyota. An automobile is a dearly cherished possession in New York City; when I cruise the outer boroughs on Sunday, I want tunes galore. So I retrieved my 1996 Aiwa cassette deck, and, attic-bound as it had been for 20 years, it was in need of repair. Via Yelp, I came across Hi-Tech Electronics, a small repair-everything-electronic shop at the east end of Canal Street, in New York's Chinatown, and a mother lode of classic audio gear and audiophile nostalgia.

The 2018 audio show season is about to start and it's not just Stereophile's coverage of high-end audio shows—which has taken a leap forward with the inclusion of Jana Dagdagan's binaural videos—that's changing. The shows themselves are on the move.

Over one busy week in 1986, Karlheinz Brandenburg laid the foundation of a technology that a few years later would upend the record business. Brandenburg, a PhD student in electrical engineering at the Friedrich-Alexander University Erlangen-Nuremberg, was figuring out how to code digital music efficiently enough that it could be delivered over digital telephone lines. A patent examiner had concluded that what the application proposed was impossible, so over a week of late nights, Brandenburg produced the proof of concept and more. It was another decade before the technology—MPEG-2 level III, more commonly known as MP3—would find its true home, the Internet.
