What motivates an artist to make great statements?

Whatever it is, it's certainly a shock to see a rock-era songwriter rediscover his muse after some 40 years treading water. So it is that Pete Townshend re-emerges at the end of 2019 with his most powerful collection of songs since Empty Glass and the best Who album since Quadrophenia.

It's even more dramatic because this is not a solo…

Let rolling streams their gladness show

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.…

Métronome Technologie AQWO SACD/CD transport and D/A processor

In an era when polar opposites compete as absolutes, it can be a challenge to acknowledge the different and equally valid ways in which audiophiles approach musical truth. But the reality is that our perceptions of how reproduced music should sound are determined, to a large extent, by how we approach the live experience. For live acoustic performances, some of us prefer a direct, up-close sound, where highs are most vibrant, the spatial nature of sounds is most distinct, swells in volume can sometimes seem assaultive, and detail is most easily perceived. Others would rather sit farther back…

When questioned about the decision to only send hi-rez PCM and DSD via HDMI I2S, Clauzel responded, "Transporting DSD needs either USB, HDMI or more complex solutions like dual AES2. We thought HDMI would be very efficient, robust, and simple. We know that audiophiles aren't very fond of HDMI, but our object was to make a transport and DAC that would fit together without adding a proprietary link between them because we want people to be able to use our transport with another converter. If our customers require that we adapt [because their DACs don't have HDMI ports], we will. If we have to…

Métronome Technologie AQWO SACD/CD transport and D/A processor Measurements

Sidebar 3: Measurements

I measured the Métronome t|AQWO and c|AQWO using my Audio Precision SYS2722 system (see the January 2008 "As We See It"), making sure that the transport and the processor were each powered from the appropriate Elektra power supply. Although the c|AQWO offers choices of six different reconstruction filters, three different output levels, tube or solid-state circuitry, and both balanced and unbalanced outputs, except when I say otherwise, the measurements were performed from the balanced solid-state outputs set to the highest level, with the Sharp Roll-off filter.…

A High-Resolution Audio Primer

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.

The response to my Update—in the article's online comment thread and elsewhere on the web—was vigorous. Some accepted the result;…
