Media Server Reviews

John Atkinson asked me to review the dCS Network Bridge ($4250), which was designed to be paired not just with the dCS Vivaldi DAC ($35,999) running the current v.2.02 software, but with any DAC. This meant I was forced to endure several months with the state-of-the-art Vivaldi as a replacement for my reference dCS Rossini ($23,999). Oh, how I suffered.

Ever since the Tokyo Electro Acoustic Company (TEAC) founded its Esoteric division, in 1987, Esoteric's slogan has been "state of the art." Given Esoteric's impressive displays at audio shows, which reflect a consistency of ownership, staff, and philosophy of engineering, design, and manufacturing, I have longed to evaluate one of their hand-assembled models in my reference system. Any brand named Esoteric, and whose top line of products is named Grandioso, had better make superior products.

A digital front end comprises several elements: data storage, library management, program control, signal distribution, signal conditioning, and digital-to-analog conversion plus all the necessary interconnections. All this can be contained in a convenient single box, or it can be distributed.

For several months, my wife and I had been living in a cozy studio apartment in New York's Financial District while our apartment underwent substantial renovations. All the old furniture was sold or donated, and decades of accumulated stuff was subjected to triage (sell, donate, or store). All my audio equipment, parts, and tools suffered the same fate. Downtown, my listening was via pretty decent headphones (B&W Px8, Audeze LCD-XC) connected to a Mytek Brooklyn+ DAC and my PC. Meanwhile, we were very busy shopping to equip the "new" apartment.

An all-in-one streamer-DAC-preamp would not have held much appeal for me if my old system was up and running. This, however, was a different time, and I was offered the Grimm MU2 for review with ideal timing.

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 7oz—it 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 Walkman—Fang Bian once owned every available model of the now-discontinued portable cassette player—the 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.

My first car was a decrepit, mustard-yellow Peugeot 304 with a navy hood. The blue hue wasn't a fashion statement; after an accident, the previous owner had gone to a salvage yard where only a blue replacement could be procured. When he grew sick of the car—because it made him look "like a frickin' ad for Ikea"—I paid him 600 Dutch guilders for the old heap, the equivalent of about $300 US. . .

Years later, when I got into hi-fi, I thought of that car and subsequent ones. What stood out to me most about high-end audio was: separates.

Is audio reviewing a futile pursuit? As much as we reviewers may strive, through subjective observation and objective measurement, to accurately describe how a component looks, sounds, and performs, we frequently find words and numbers inadequate to communicate the mysteries that abound in the transcendent realm of music. How can we fully share what we feel when a component allows us to experience, sometimes afresh, often in a new way, sounds that elicit joy, sorrow, terror, or more subtle emotions? How do we encapsulate in words and measurements the sonic equivalent of the wide-eyed wonder that shines through a baby's eyes as she discovers something new?

Such emotions—hence such questions—can arise when we move from one music server to another, or even between different software running on the same server. They are particularly intense in the case of this review of the Ideon Absolute Stream meta edition (2024) ($24,000) and its optional add-on, the Ideon Alpha Wave LAN Optimizer ($6900), considering that the review lacks measurements.
