I decided to test the low-frequency performance of The Nines. It pleased and amused me to learn that John Atkinson uses a Taylor Swift tune, "All Too Well (Taylor's Version)," from her remade Red (24/96 FLAC, Big Machine Records/Qobuz), to test low bass. It's a good tune for that purpose, with a prominent bassline dropping an octave at 2:25, when she sings, "'Cause there we are again in the middle of the night." The Nines clearly reproduced the descending low-frequency energy, but pushing the SPLs pushed the fuzziness. These little boxes are great at reasonable volumes, but they simply…

Sidebar 3: Measurements
I performed the measurements with the Klipsch The Nines Primary speaker (serial number 107128623160250). Before I started the testing, I installed the Klipsch Connect app on my iPad mini and paired it with the speaker with Bluetooth. I used the app to set the equalizer controls to Flat, the low-frequency equalization to Other, which is used for a free-space placement away from the room boundaries, and to turn off the Dynamic Bass function, which adjusts the low-frequency extension up or down as the output level changes.
The app identified the speaker's…
Anthony H. (Tony) Cordesman, who wrote high-end equipment reviews for Audio, Stereophile, and The Absolute Sound (TAS), died suddenly last week. Cordesman also wrote articles and offered commentary about national security; scan the interwebs and you will learn of his deep and wide impact on that field. (The Washington Post obituary is here, and here's an appreciation by a fellow national security expert.)
Readers of a certain age may remember Cordesman's dead-serious delivery of crucial perspective and insights alongside Peter Jennings during ABC News's coverage of the first Gulf…
I said to Hank Williams, how lonely does it get?
Hank Williams hasn't answered yet
But I hear him coughing all night long
Oh, a hundred floors above me in the tower of song
—Leonard Cohen, "Tower of Song"

When I was a child growing up in Moscow in the 1970s, our pop-musical landscape was dominated by the so-called bards. They were Soviet counterparts to singer-songwriters from the West, and they sang literate, knowing lyrics while accompanying themselves on acoustic guitars. Even the word used to describe them—…
The IRS Tapes: Who'll Buy My Memories (1991)
In 1990, while Nelson was golfing in Hawaii, IRS agents seized most of his assets, including several homes and a farm, and presented him with a $16.7 million bill for years of unpaid taxes. During the ordeal, Nelson's daughter and his lawyer took turns hiding his guitar, Trigger, from the eagle-eyed feds. "We try to work with taxpayers," an IRS spokeswoman told The New York Times the following year, "and if we have to come up with some creative payment plan, that's what we're going to do." The creative payment plan included this double…
For some, it takes the likes of Scheherazade to seduce; for me, simple sound will suffice. But not just any sound. If I'm going to enter into a relationship with an audio component, I want it to last.
I don't know anyone who, having heard the JMF Audio system at AXPONA 2023—the HQS 6002 dual-mono power amplifier ($40,000; footnote 1) and PRS 1.5 dual-mono line stage preamplifier ($36,000) with Harbeth M40.3 XD speakers—did not rave about the sound. In my show report, I credited the system, assembled by Fidelis Distribution and Audio Skies, with delivering "some of the finestsounding music…
The rear panel is dominated by large, vertical heatsink fins. To their left, top-to-bottom, are the XLR input, JMF Audio's proprietary gold-plated, 120A-rated, 6mm-diameter LSS output terminals designed for JMF speaker cables, then WBT modular gold-plated output terminals for spades, wire, or 4mm-diameter banana plugs. JMF Audio recommends their own speaker cables, but to keep things as simple as possible, I used my usual cabling. Below the outputs sits a ground connection that may be used to link the loudspeaker's shield to the amplifier's case—I didn't need it—and the connection point…
