Music Matters, the mostly annual audio showcase from Definitive Audio in Seattle, made a welcome return March 8–9 after a two-year pandemic-imposed hiatus. Divided into two two-hour sessions, the 16th edition of the private, ultra-concentrated audio show in miniature saw invitees moving between 20-minute presentations in four rooms, with ample time left for visiting systems in two others and schmoozing with industry legends.
Between several national and regional product premieres, presenters at Music Matters 2023 emphasized the importance of Definitive Audio (with locations in…
Which is not to say there aren't transformative events. Prior to my lightning-strike moment—about which, more in a minute—the blues were all around me, as they always are around all of us. As a kid attuned to rock'n'roll,…

You might think that by 1931—the year Igor Stravinsky (1882–1971) completed his unforgettable Violin Concerto in D Major—orchestral instruments were the same as those used today. Far from it. According to the website of Claire Givens Violins (footnote 1), pure-gut D strings began to disappear after WWI and were…
At the beginning of the 2022 novel Checkout 19, by Claire-Louise Bennett, I encountered some ideas that resonate in interesting ways with my recent experience of recorded music. The first idea is expressed in the quote above: You take out many books from the library—as many as they'll allow—and you don't read any of them all the way through. There's too much temptation to move from one to the other, "tossing one…
After having built many amplifiers as a young man, Sakuma-san experienced an epiphany: Amplifiers that measured well often failed to make him feel deeply. He soon…
The La Scalas' sound varies remarkably depending on amplification, and they demand and reward high quality; the prospect of them being driven by a big-box-store receiver fills me with sadness. Choosing the right amplifier to use with them wasn't entirely straightforward and required a fair amount of trial and error. The Klipsches' sky-high sensitivity may suggest otherwise, but a single measurement never tells the whole story. I listened to them with five amplifiers controlled by the superbly transparent and tuneful PrimaLuna EVO 400 line stage; here's what I heard.

Because of the Klipsch La Scala's bulk—it weighs 201lb—I measured the speaker in AH's apartment. I used DRA Labs' MLSSA system and a calibrated DPA 4006 microphone to measure the La Scala's behavior in the farfield, and an Earthworks QTC-40 mike for the nearfield and in-room responses. The loudspeakers were driven by the Manley Mahi Mahi amplifiers AH used for his auditioning. For the measurements, I left off the grille that covers the high-frequency and midrange horns, as AH preferred the sound without them.
The La Scala's sensitivity is specified as an…
