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.

In the 1980s, the CD nearly pushed the LP to extinction. Nearly. For all the claims of "Perfect Sound Forever," the main thing offered by the CD was convenience.

Then, in the mid-1990s, the MP3 and the Internet made it easy to extract and distribute the information encoded on a CD. Secret websites raced to be the first to distribute free MP3s of new recordings, sometimes even before they were released. This went on for years, undermining record-company profits, before Napster came along and gave the record industry a high-value lawsuit target: no more suing widows and small children.

Lately it seems that the more Rega charges for one of its turntables, the less you get—and from Rega's performance perspective that's a good thing.

While some turntable designs pile on the mass, hoping to tame resonances and better isolate the record from the outside world, Rega has long advocated ultralow-mass designs. What's up with that?

This marks the end of our Florida Audio Expo 2020 coverage, but before I wrap things up, I'd like to mention a few more standout rooms with super systems.
