LATEST ADDITIONS

(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."

The components I needed to choose for my first system were never in doubt: a turntable or record changer, an integrated amplifier, and a speaker. One of each, please, in those mono days.

Today, even in stereo, that trinity would be regarded as rather traditional—or, if you prefer, purist. Digital has exploded the range of source options and loudspeaker options. Yet amplifiers have not changed much in how and what they do.

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.
