Media Server Reviews

Apple may not have been the first to market with a portable digital audio player, but its original iPod defined the genre: a device small enough to fit into a shirt pocket. When companies like Acoustic Research, Astell&Kern, Fiio, HiFiMan, and Questyle introduced portable players that could play high-resolution files, they echoed the iPod's form factor. The exception was the Toblerone-shaped PonoPlayer, but even that was small. The subject of this review is another exception: The DMP-Z1, from Sony's Signature Series, is comparatively enormous—almost the size and weight of a regular preamplifier. At $8500, it's also considerably more expensive than other players.

I have reviewed several network-connected music servers in recent years, from Antipodes, Aurender, and NAD. All performed well but are relatively expensive, and their associated player apps didn't equal Roon's user friendliness in terms of interface, organization of the library, and inclusion and updating of metadata. So when Roon Labs introduced their own server, the Nucleus+, I first reviewed and then purchased it, along with a lifetime subscription to Roon. But at $2498 without an internal drive for storing music files, the Nucleus+ is still relatively expensive, and even Roon's less-powerful Nucleus costs $1398. I was still on the lookout for a server that would be more accessible to our budget-minded readers.

The late Julian Vereker, the sharp-minded former racing driver who founded Naim Audio and designed its first products, did so because he wanted audio amplification of a quality he felt no one else was making at the time, reasoning that if he wanted such a thing, so might others. Thus came about Naim's first domestic-audio product, the distinctive NAP200 solid-state amp (1973).

Sssssshhhhhh—I forget what music was playing, but as the sound faded away, I could hear a loud hissing coming from the 2011 i7 Mac mini I was operating headless with Roon 1.3 to play files over my network. Checking the mini's shared screen on my MacBook Pro revealed that it was completely unresponsive, so I yanked its AC cord, after which it wouldn't boot up.

This was the second time the Mac mini had died. The first time, in 2015, the local Apple Genius Bar had repaired it. This time, the hipster at the Genius Bar turned me away: "We don't offer repair work on vintage computers."

In February 2017, Bryston announced the latest upgrade of their Digital Player, introduced in 2011 as the BDP-1 ($2195), and upgraded in 2013 to the BDP-2, with a faster Atom N450 processor. The new BDP-3 Digital Player ($3495) comes equipped with an even faster Intel Quad-core processor; a Bryston-manufactured integrated audio device (IAD) in place of a third-party sound card; a custom Intel Celeron motherboard; a bigger power supply; and two additional USB ports, for a total of eight—three of which use the faster USB 3.0 protocol. Two USB 3.0 ports run on an entirely separate USB bus, making the BDP-3 compatible with the Streamlength protocols used by DACs from Ayre Acoustics and Berkeley Audio Design.

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.

Back in May 2014, I reviewed NAD's Masters Series M50 Digital Music Player ($2499) and M52 Digital Music Vault ($1999 with 2TB storage). At the 2017 Consumer Electronics Show, NAD announced the M50.2, which is almost identical to the original M50 but now incorporates two 2TB hard disks, arranged as a 2TB RAID array, to ensure data integrity, and adds TosLink and coaxial digital inputs, Bluetooth with aptX for streaming music from a smartphone or tablet, and two single-ended analog inputs—all for $3999, or $499 less than the combined cost of the two earlier products. Like the M50, the M50.2 offers WiFi and Ethernet connectivity, and has a CD drive, accessible via a slot on the front panel under the color TFT touchscreen, that can be used to play CDs, or rip them as FLAC, WAV, or high-bit-rate MP3 files.
