The image above is not a modernist oil painting. It's an airport x-ray of my friend Jeffrey Jackson's backpack.

Can you identify its contents? Did you notice the red rectangle alerting the inspector of a suspicious object? Do you know what that suspicious object is? Or what it is worth?

That ominous-looking black silhouette is a 1930s-era Western Electric 555W "receiver"—ie, a compression driver for use with a horn. It's about 10" in diameter and weighs around 15lb. It requires a 7V DC/1.4A power supply for its field-coil magnet and would cost about $8000 to replace.

The stars are matter. We are matter. But it doesn't matter.—Don Van Vliet

Only sensibilities trained on poetry can wholly appreciate it.—T.S. Eliot (writing about Djuna Barnes's Nightwood)

In the 17th century, steam engines began appearing throughout Europe and Asia, ushered into existence by any number of different inventors. More recently, multiple inventors conceived and cooked up the atomic bomb, the jet engine, and the solid-body electric guitar.

(February 28) High End 2020, aka Munich High End, has been canceled “due to the current worsening trend with respect to the spread of the novel coronavirus.”

The Sonus Faber Olympica Nova 1 ($6500/pair) is the company's latest stand-mounted, two-way monitor—a lineage that began with their first speaker, the Minima, which I reviewed some 24 years ago. Like the products that followed, the Minima featured a 1" silk-dome tweeter and a 4" reflex-loaded paper-based midbass driver, both attached to a leather-covered baffle and housed in a beautiful wood cabinet, hand-crafted in Italy. I enjoyed the Minima's sound, as did this magazine's Sam Tellig, who praised its "sweet, forgiving, slightly rolled-off on top, and somewhat ripe . . . mid-to-upper bass," with superb focus and imaging that was a "treat for sore ears."

On Friday, February 28, 3–7pm, Audio Advisors, at 2271A Palm Beach Lakes Blvd., West Palm Beach, Florida, will present the new Wilson Audio Chronosonic XVX loudspeaker. Wilson's Peter McGrath will be there. Space is limited so please R.S.V.P. to Rudi, either by email rkothe@audioadvisors.com or phone, at (561) 478-3100.

The idea of using digital signal processing (DSP) to convert digital audio data sampled at 44.1kHz or 48kHz to a higher sample rate is not new. I first heard the beneficial effects of upsampling at Stereophile's 1998 hi-fi show in Los Angeles, where a pro-audio dCS 972 digital-to-digital processor was being used to convert 16-bit/44.1kHz CD data to a 24/192 datastream.

January's Industry Update included a report on a scientific article presented at last year's AES meeting, in which the authors used test tones and a modest audio system (albeit in an anechoic chamber) to prove that listeners can discriminate between high-rez and CD-rez audio. This is important because scientific evidence of an audible difference between high-rez and CD-rez music is considered weak by some, even as anecdotal evidence grows stronger by the day.

As I pondered this, I recalled a recent paper I'd seen in the Journal of the Audio Engineering Society but hadn't yet read. "High Resolution Audio: A History and Perspective," which the AES has made available free online, does precisely what the title says: reviews the history of digital audio beyond CD-rez and frames the issue of high-rez audio's audible superiority on the basis of the available evidence.
