I don't know Gram Slee from Gram Parsons, or which House he was in at Harry Potter's Hogwarts School, but let me tell you: If you'd just been listening to a bunch of budget phono preamps, as I had, then came upon the GSP Audio Era Gold Mk.V, you'd think someone had switched out not just the phono preamp but your entire system. You might think you were listening to a different pressing or a different cartridge. How can this be?
Some time ago in these pages, Anthony H. Cordesman observed rather ungraciously that the whole line of Hafler electronics "could do with reworking." This was interpreted by many readersincluding the good people at the David Hafler Companyas meaning that AHC felt the entire Hafler line to be mediocre. In fact, he does not. (He had given a Hafler product a positive review a few issues previously.) Tony's comment, however, did express a sentiment that most of us at Stereophile have shared for some time: a feeling that Hafler products had slipped from the position of sonic preeminence which they enjoyed during the 1960s and '70s to one of mere excellence in a field where only preeminence is acclaimed.
When it comes to getting audio from a PC via its USB port, the buzzword du jour is asynchronous. This cryptic term refers to which device has control over the timing of the audio data being streamed from the computer: the computer itself, or the device receiving the data. It might seem logical to have the computer control the timing, but this is not so. When digital audio data are converted to analog by a D/A converter, control over exactly when each dataword is converted is critical for the best quality of sound. Any uncertainty in that timing manifests itself as analog distortion, aka jitter.
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.
Head-Direct's HiFiMan HM-602 is the second in a growing line of perfectionist-quality portable music players designed by Fang Bian, a 31-year-old audiophile and student of nanotechnology at the City University of New York's Hunter College. Bian's first HiFiMan design was the larger, heavier, more versatile HM-801 ($790; see my review here). In building the HM-602, Fang sacrificed the '801's removable amplifier module, 15V rechargeable battery, and coaxial input, thus creating a smaller, more portable product. Much sleeker and less substantial than the '801, the HM-602 measures approximately 4" L by 2.5" W by 1" D and weighs just 7ozit can rest comfortably in the palm of a hand or a coat's inner pocket.
Overall, the HM-602 has a handsome, rather serious appearance: With its gold controls and its fine metallic finish, which at times seems a deep green and at others takes on a smoky charcoal, the HM-602, like its predecessor, exhibits an air of elegance and sophistication. And while the HM-801 proudly takes after Sony's famed WalkmanFang Bian once owned every available model of the now-discontinued portable cassette playerthe HM-602 much more closely resembles Apple's iPod Classic. On its front panel, below the 2" LCD screen, the HM-602 has a four-way control ring similar to the iPod's scroll wheel, and three sliding switches: Power, Hold (deactivates controls while music is playing), and DAP/USB.
"Uhh! What is it?" I was being prodded on the arm. Admittedly it was gentle, almost polite prodding, but prodding it still was, a rude disturbance of the cocoon I had woven around myself in seat 31J of the American Airlines MD-11 winging its way across the North Atlantic. I pushed Pause on the Discman, insensitively not waiting for an opportune cadence in the Brahms Piano Quintet that had been my erstwhile virtual reality.
When, on his long-running TV variety show, Jackie Gleason used to order up some "traveling music" from music director Ray Bloch, he got a live orchestra's worth. But when Gleason, a composer and conductor in his own right (he wrote his show's unforgettable theme song, "Melancholy Serenade"), actually traveled, his listening options were severely limited compared to ours. By the time the comedian died in 1987, Sony had introduced the Walkman cassette player, but Apple's iPod was still more than a decade in the future.
Like most people, I'm not interested in long, windy essays about audio reviewing, having barely enough time and interest for audio itself. But I do perk up when the debate turns to the audio reviewer's purpose in life: Should I write about everything that crosses my path, or should I limit my attention to those products that interest me, and that stand a chance of being good?
No history of the computer-audio marketplace could be complete without some mention of High Resolution Technologies, the California company whose Music Streamer was, in 2009, the first perfectionist-quality USB digital-to-analog converter to sell for as little as $99. One could argue that HRT's entire business model has contributed to shaping our attitudes toward the hobby: Because digital-audio technology continues to evolve at such a rapid pace, HRT has introduced a succession of newer and ever more effective Music Streamers, occasionally to the obsolescence of their predecessors; yet because those products have all been so affordableremarkably and laudably so, given their thoroughly American provenancewe tend not to mind.
Art Dudley and others have covered the first products released by HRT, and now the company has added to its product line a Pro version of its Music Streamer, which sports balanced circuit design from tip to tail.
Housed in the same simple, functional, six-sided case of extruded aluminum as HRT's other products, the Pro is painted a bright blue to distinguish it from the Music Streamer II (red) and Music Streamer II+ (gray). At 5.6" it is also a tad longer than the others, and includes a single B-type USB 1.1 jack centered on one end, and two small, fully balanced TiniQ output jacks on the other. More about these special mini sockets later.
My favorite moment in the Zack Snyder film Watchmenapart from the Dylan-fueled title sequence, which itself contains some of the most memorable scenes in recent cinemacomes when retired crimefighter Daniel "Nite Owl II" Dreiberg arrives home to find the doctrinaire and mildly crazy Walter "Rorschach" Kovacs in his kitchen, eating beans straight from the can. The startled Dreiberg asks his visitor, "Would you like me to heat those up for you?"
Every now and then an affordable product comes along that's so good, even wealthy shoppers want it. Past examples in domestic audio include the Rega RB300 tonearm, the original Quicksilver Mono amplifier, the Grace F9E phono cartridgeeven Sony's unwitting CD player, the original PlayStation. Based on word of mouth alone, one might add the HRT Music Streamer+ to that lauded list.
I like reviewing loudspeakers. The more you become familiar with the art, the greater the sense of anticipation as you open up a pair of cartons. A visual inspection of the speaker always reveals a challenging mixture of the familiar and the new. The size of the cabinet is always the first cluehas sensitivity been a design priority or was low-frequency extension uppermost in the designer's thoughts? You espy a known drive-unithas this tweeter's propensity for upper-presence sizzle been tamed? You find a reflex port on the rear panelhas the temptation to go for a "commercial," under-damped bass alignment been successfully resisted? You spot factors which intuitively seem wrong for precise stereoa wide baffle lacking any kind of absorbent covering for diffraction control; a grille frame which puts acoustic obstacles in the way of the wavefront emerging from the tweeter.
It was 20 years ago that I began audio reviewing as a second career. It was also 20 years ago that I made my first very expensive audio purchase: a pair of Infinity RS-1b speakers. The RS-1b was a landmark speaker in its day, and very costly for the time at $5500/pair. (I think my dentist has just spent more than that on a TV.) In retrospect, the RS-1b was an extraordinary value. With four large towers, more than 30 drivers, and a servo network and a passive crossover, the Infinity RS-1b resolved a significant amount of detail, was capable of large dynamic swings, had pinpoint image specificity on a wide, deep soundstage, and was capable of reproducing a convincing bottom octave in the right room when paired with the right associated equipment. Its main weaknesses were a relative lack of coherence due to its use of three different types of drivers to cover the various frequency ranges, and both the midrange/tweeter towers and woofer columns were picky about amplifier matching.
