As we approach the end of the 21st century's "oughts" decade, many feel that playing music from a discrete physical medium is positively 20th century. Much of my own music enjoyment now comes from computer files, often high-resolution, streamed to my high-end rig via a Logitech Transporter or Bel Canto USB Link 24/96. It is perhaps a paradox, therefore, that high-end audio companies are still devoting so much effort to developing expensive, state-of-the-art disc players. In April I very favorably reviewed Meridian's superb 808i.2 CD player–preamplifier, which costs $16,995 as reviewed, and…
The final card, shielded to prevent RF interference, carries an embedded PC running the Linux operating system. (An external display hooked up to the 1021's VGA output will display the boot routine before mirroring the front-panel display.) This PC handles all the display and user-interface chores, and manages the embedded disc database. The final operation at the factory before packing up a 1021 for shipping is to load its non-volatile memory with the most recent version of the database. (Other than noting that it doesn't appear to be the Gracenote/CDDB database, I'm not sure which the…
I sat back to listen, but something was wrong. Instead of the first track being the dark-hued chorus "Kommt, ihr Tüchter, helft mir klagen," it was the Evangelist's recitative "Da Jesus diese Rede vollendet hatte," which is actually the second track. The first file was on the disc but had not been recognized. I encountered missing files with other DVD-Rs I burned. The most extreme example was with the Charles Mackerras performance of the late Mozart symphonies that I had purchased from the Linn website and burned to disc; of the four symphonies, the only files the Boulder could identify and…

Sidebar 3: Measurements
I examined the measured behavior of the Boulder 1021 using the Audio Precision SYS2722 system (see www.ap.com and "As We See It" in the January 2008 issue), as well as, for some tests, our Audio Precision System One and the Miller Audio Research Jitter Analyzer. I used my regular CD-R of 16-bit test tones, as well as a data CD-R on which I had burned 24-bit/96kHz- or 192kHz-sampled WAV files of a subset of those test tones.
The Boulder's maximum output was to specification, at 4.06V RMS; this was the same with the output set to Fixed volume, or to…
Sennheiser's long-awaited (seven years) HD800 sure isn't subtle—at least, not in appearance. The HD800's large earpieces are made from a combination of absorbing composites and functional metal accents, and are huge. Of course, they have to be to house the 56mm ring-radiator transducers—and to mount them so they're firing "back" to your ears from the front. Also not subtle is the price: $1399.95.
On the other hand, Sennheiser wasn't going for subtle improvements in designing and building the HD800. After all, they'd already tried subtle when they introduced the HD650 as an…
Dynamic, too. Part and parcel of that extraordinary background silence was how nuanced were the shades of soft and softer—and loud and louder—through the HD800s. Kavi Alexander's lovely recording of Szymanowski's three Paganini Caprices, Op.40, with Ruggiero Ricci and Brooks Smith (CD, John Marks Recordings JMR 11), was a prime example. Ricci's violin sounded three-dimensional, ranging from tender phrases to stentorian exhortations. Whether by itself or floating above and far forward of Smith's piano, there seemed to be an entire symphony orchestra in the violinist's hands.
In the second…
