Media Server Reviews

In the summer of 2021, MoFi Distribution's Jonathan Derda emailed me about the South Korean HiFi Rose brand. "This brand strikes me as being the spiritual successor to the original SlimDevices Transporter and Squeezebox Touch," he wrote. "We're all really excited about it."

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.

In ancient times, when I first ventured beyond playing files stored on a USB stick or NAS to streaming from Tidal and Qobuz, I ran a USB cable between a MacBook Pro and my DAC. For playback software, I alternated between Amarra, Audirvana, and—sometimes with a dCS DAC—dCS Mosaic.

The Innuos ZENith Next-Gen ($20,700 as equipped) does what streamer-servers do: store music files, read them into memory, and send them on to a D/A converter to make music. In Innuos's complex (yet logical) lineup of streamers and streamer-servers, the ZENith Next-Gen sits just below the flagship Statement and above the ZENith Mk.3. The ZENith Mk.3 remains in the Innuos lineup for now but will be replaced at AXPONA shortly after this issue hits mailboxes and newsstands.

Though similar in many respects, with a very similar appearance, these two products—the ZENith Next-Gen and the ZENith Mk.3—are very different beasts. There is one rather obvious difference: a CD slot on the Mk.3 (with, of course, a CD drive inside), which makes it easy to rip CDs to the server's internal memory. This feature is absent from the more purist ZENith Next-Gen. But with the Next-Gen you can have your cake and eat it: Attach any USB CD ripper to one of the USB ports, and it will work just the same as the built-in ripper on the Mk.3. The other differences between the Mk.3 and the Next-Gen are less obvious, but those differences go much deeper; see the Details section in this review.

My friend Ed (not necessarily his name) used to be an audiophile. Ed had a great-sounding pair of floorstanding Joseph speakers, optimally placed so as to create a magic soundstage when he sat in the sweet spot. His component rack featured such famous high-end names as Mark Levinson, Meridian, and Z-Systems. But then Ed went DSL and discovered MP3s. Pretty soon, he was hanging as many hard drives on his PC as he could manage. His Josephs and his Levinson CD player gathered dust. Ed was enjoying his music sitting in front of his high-end Dell, with an active NHT Pro mini on either side of the monitor.

In March, to celebrate Marantz's 60th anniversary, the company launched the subject of this review, the Reference NA-11S1 network player ($3499), which Ken Ishiwata described to me as "a new start, a new era" for Marantz. Michael Fremer attended the European press conference announcing the NA-11S1, and I subsequently talked to Ishiwata via Skype.

It has a fan, it won't work without a monitor, and it contains a 750GB hard drive—for some audiophiles, that's a trifecta of reasons not to buy the McIntosh MS750 music server ($6000).
