I measured iFi Audio's Pro iDSD (serial no. 3002000468, a different sample from the one auditioned by HR) with my Audio Precision SYS2722 system (see the January 2008 As We See It"). I used both the Audio Precision's S/PDIF outputs and USB data sourced from my MacBook Pro running on battery power and playing WAV and AIFF test-tone files. Apple's USB Prober utility identified the iDSD as "iFi (by AMR) HD USB Audio" from "iFi (by AMR)," and confirmed that its USB port operated in the optimal isochronous asynchronous mode. Apple's AudioMIDI utility revealed that, via…
From last week's contemporary realities, as viewed through the lens of David Chesky, we move back in time to 1707–1710, when the emotionally overwrought women, mythological subjects, shepherds, shepherdesses, and nymphs of Handel Italian Cantatas were in vogue. If those subjects strike your fancy, and/or you love baroque artistry and great singing, this new Erato recording from Emmanuelle Haïm's Le Concert d'Astrée, French lyric coloratura soprano Sabine Devielhe, and Franco-Italian mezzo-soprano Lea Desandre belongs on your must-hear list.
The recording captures both women in…
"They expect 180,000 people this year," the Lyft driver told me as we headed to the Strip shortly after sunset. "That's 10,000 more than last year!"
Does that mean there will be 10,000 more gadgets on display?
One thing's for certain: there will be far less to see on the floors of the Venetian Hotel, which "high performance audio" once called home. The last time I glanced at a site map, there were only 25–27 high performance exhibit rooms scattered over three floors. In addition, I know of only two companies that are exhibiting off-site, and no High Resolution Pavilion where…
Berlioz: Symphonie fantastique

It is easy to forget that the hi-fi movements—the "March to the Scaffold" and the "Dream of a Witches' Sabbath"—comprise barely a third of the music in the Symphonie fantastique, yet when we listen to most of the available versions of this, we can understand why the first three movements are usually passed up by the record listener. Two are slow and brooding, one is a wispy sort of waltz, and all three require a certain combination of flowing gentleness and…
Dmitri Shostakovich (1906–1975) was hardly the first composer to run headfirst into opposition from political authorities. In his case, however, the pushback was so extreme that it affected everything he wrote thereafter.
In early 1936, after the style and subject matter of his opera Lady Macbeth of Mtsensk clashed with the so-called proletarian aesthetic of Russian dictator Joseph Stalin (1878–1953), Shostakovich was denounced by the official state newspaper, Pravda. From then on, his symphonies reflected either his defiance of decades of Socialist realism, or attempts to appease the…
After a few minutes in the VTL/Wilson/Nordost room on the 29th floor of the Venetian Hotel, the challenge I faced in covering CES 2019 was staring me in the face. The good news for me, and the bad news for exhibitors, was that visitor traffic was extremely light. To only two rooms did I need to backtrack because exhibitors were totally occupied with other visitors when I paid an initial visit. But, on the other hand, the sound in some rooms was so good, the musical selections so compelling, and the exhibitors so hungry for attention from someone that I had an extremely difficult time tearing…
As a longtime user of Nordost's cable and AC-power products, my ears opened wide when they released their three QKore Ground Units and QKore Wire at High End 2017, in Munich. While I've never questioned the importance of proper electrical grounding, to prevent problems with safety and noise—the latter including measurable noise generated by transformers, appliances, LED lighting, power supplies, and Bluetooth, WiFi, and cellular devices—I couldn't fathom what difference a passive grounding device might make in a high-end system that, in my case, is fed by an 8-gauge dedicated line with its…
Setup decisions were simplified when Taylor explained that, since the component LVAPs in the QKore3 and 6 are identical, and the power-product LVAPs in the QKore1 and 6 are also identical, if I were to use the QKore6 to connect only three components plus a power product, the sound would be equivalent to connecting a separate QKore1 and QKore3. It got even easier when I discovered that the only open digital connectors on my components were single-ended BNC and RCA. This meant that I wouldn't be able to compare the sounds of the QKores' grounding via single-ended vs balanced connectors.
