Occasional Stereophile contributor Steve Guttenberg publishes a YouTube channel about audio that has achieved an impressive reach. As Steve told me in a conversation I had with him last December, 22% of his 98,000 subscribers (at the time we talked) are under 34 years old, and, to judge from the comments, most of them don't read Stereophile!!!! "It would nice to introduce you to them!" said Steve, and proposed he interview me and post the video to his channel when it hit the magic 100k number, which it did on January 9.
Steve visited my place in Brooklyn just before the New Year, and we spent an afternoon talking about audio, magazines, measurements, and music.
On a snowy day in March 2019, the first room I visited at the Montreal Audio Fest, hosted by retailer Audio by Mark Jones, featured the world premiere of the Magico M2 loudspeaker. The soundstaging produced by these elegant towers was palpable, the full-range tonal balance superbly uncolored. Both aspects reminded me of my experience of Magico's S5 Mk.II loudspeaker, which I enthusiastically reviewed in Stereophile's February 2017 issue. Accordingly, I made a note that the M2 was going on my "must review" list. Seven months later, Magico's Alon Wolf and Peter Mackay visited to set up a pair of M2s in my listening room.
Even as digital/analog processors were becoming a hot product category in the early 1990s, audiophiles were also learning that timing uncertainties in the AES/EBU and S/PDIF serial datastreamsjitterwould compromise any improvement in sound quality offered by these DACs. Some companies therefore introduced products to reduce or eliminate jitterin the November 1994 issue of Stereophile, Robert Harley reviewed three such products: the Audio Alchemy DTI Pro, the Digital Domain VSP, and the Sonic Frontiers UltrajitterBug. I still have Stereophile's review samples of the UltraJitterBug and VSP, along with two contemporary DACs: a PS Audio UltraLink and a Parts Connection Assemblage DAC-1.
As our reviews of these products were published before Paul Miller's and the late Julian Dunn's development of the "J-Test" diagnostic signal, I performed J-Test jitter measurements to bring that 1994 review into the 21st Century. You can see what I found here.
When I performed the measurements of the Q Acoustics Concept 500 loudspeaker to accompany Thomas J. Norton's review in March 2019, I was impressed by what I found. The floorstanding Concept 500 offers a high level of audio engineering excellence for its price of $5999.99/pair. When I attended a Q Acoustics press briefing a few months back, where the English company announced the US availability of their stand-mounted Concept 300, I didn't hesitate to ask for a pair to review.
High-quality playback of digital audio is evolving in two opposed directions. One is where a smart wireless loudspeaker, like the KEF LSX or DALI Callisto 6 C, needs to be connected to a simple source of data. The other is where a smart amplifier takes the data from wherever it needs and sends it to a pair of dumb loudspeakers. NAD's Masters Series M32 integrated amplifier ($4848 with its optional MDC DD-BluOS module), which I reviewed in May 2018, is a great-sounding example of the latter approach.
In the spring of 2019, NAD introduced the Masters Series M10 ($2749). At first I assumed that the M10 was a stripped-down, less-powerful version of the M32, but the new amplifier offers a unique set of features.
Unlike the world of recorded music, where streaming has decimated sales of physical products, book publishing is seeing the reverse trend: sales of eBooks are declining while those of both hardback and paperback books are recovering. I have been a book junkie all my lifethe two long walls of my listening room are lined with floor-to-ceiling bookshelves and I have many boxes of books in storagebut these days almost all my book reading is with the Kindle app on my iPad mini.
"Stirring the stew" is what I've heard it called when a company introduces a new version of a product every three or four years. When a new product is launched, sales generally rise rapidly to a maximum and then slowly decline. If the stew is stirred every few years, plotting the product's sales volume against time results in a sawtooth wave, without sales ever dropping close to zero.

To many audiophiles, high-end audio manufacturers must seem like monolithic entities, enduring for what seems like forever, like cliffs beside a familiar path. But as Paul McGowan explains in this unputdownable autobiography (footnote 1), behind the facade of stability things can be in financial turmoil, with success equally as risky as failure.
It is said that while any competent engineer can design a superb loudspeaker if allowed an unlimited bill of materials, the true test is being able to produce a great-sounding, budget-priced speaker out of parts that cost a mere handful of dollars. With PSB's Alpha series of bookshelf speakers, Canadian engineer Paul Barton has illustrated this truism many times over the years.
PS Audio's Paul McGowan has been sending out a daily newsletter by email since 2011. In his May 29, 2019 epistle he asked, "What would our world of high-end audio look like if there were only active wireless loudspeakers? If even the half-a-million-dollar mega-beasts were internally amplified and connected via wireless and controlled from an iPad? No more boxes. No more wires and cables. Only speakers."
