The January 2011 issue of Stereophile is now on newsstands—a whole new year, a whole new volume of your favorite hi-fi magazine! And we’re starting the year off right. In my opinion, this is the best-looking cover we’ve put together in a while. The layout is clean and well-balanced, the image is dynamic, and the colors are vibrant and attractive. Those colors largely stem from the cute, little Chordette Gem DAC. Graphic designer, Natalie Baca, borrowed the fuchsia of the Chord’s chassis for the cover’s border, and took the gold of the Chord’s output jacks for our logo and cover…
Art Dudley wrote about the HRT Music Streamer II+ in December 2010 (Vol.33 No.12):
Consumer audio hasn't enjoyed many success stories in recent years, so this one stands out: According to distributor Elite Audio/Video, their USB-based Music Streamer D/A converters, designed and built in California by High Resolution Technologies, have been kicking ass, taking names, and generally scaring the hell out of everyone else who wants a share of the computer-music market.
But the Metamucil of technology doesn't settle in the bottom of the glass for very long, especially when audio…

The weekly Vote! Page is one of the most popular features of the Stereophile website, and the August 22 question, "Should Stereophile review more or fewer computer-audio products?", generated a record number of responses. No less than 88% of those responding asked for more coverage of products that allow a computer to be a legitimate source of music in a high-end context. Just 7% of readers wanted less coverage.
We have been trying to meet this demand for some time. I wrote a primer on the subject a few years ago (footnote 1), and more recently have been auditioning relatively…
I changed to the Esoteric D-07 processor that I have in for review, now using the RCA version of the Halide Bridge. (The Esoteric has RCA S/PDIF inputs, whereas the Benchmark has a BNC.) I had previously auditioned the Esoteric feeding its AES/EBU input from the Ayre C-5xeMP's digital output, and if there was a difference to be heard when I switched to the Mac mini driving the Halide Bridge, I was hard-pressed to hear it.
I swapped the Esoteric for the Logitech Transporter DAC and again compared disc sources played on the Ayre and fed to the Transporter's AES/EBU input to the BNC Halide…

Sidebar 3: Measurements
I examined the measured behavior of the BNC version of the Halide USB converter using the Audio Precision SYS2722 system (see www.ap.com and "As We See It" in the January 2008 issue), as well as the Miller Audio Research Jitter Analyzer. I played test tones at various sample rates and bit depths from BIAS Peak Pro 6 on an Intel MacBook running OS10.6.4, with some tests repeated on a dual-core PC running Windows 7 and Adobe Audition 3.0.
The Halide operated at whatever sample rate the audio file had been recorded at, provided the sample rate had been set…
I've always enjoyed the time I've spent with NHT loudspeakers. The two bookshelf models I've reviewed—the SB-3 (Stereophile, November 2002) and its successor, the Classic Three (November 2006)—shared NHT's "house sound": liquid, balanced, and dynamic, with little coloration, and a slightly forward and lively midrange. The newer Classic Three, still in production, sounded more refined, natural, and detailed than the SB-3. I like to see speaker designers whose work improves over time.
So when NHT approached me about reviewing a new floorstanding model with a small footprint, the…
The NHT's neutral midrange made it an excellent match for small-ensemble jazz recordings. I focused on Herbie Hancock's simple yet dynamic chordal comping on his composition "Blind Man, Blind Man," from My Point of View (CD, Blue Note CDP-84126). The sound of his piano was warm and woody, but every percussive attack was perfectly integrated with the rhythm section, with no trace of rounding or excess sharpness. Jazz guitar was also remarkably realistic. Kenny Burrell's lower-register melodic work in "Main Stem," from Jimmy Smith's Fourmost (CD, Milestone MCD-9184-2), recorded live at Fat…
