Media Server Reviews

On a cold, clear February morning, I attended my first in-person press event since the beginning of the pandemic. Marantz had invited me to a small group session in a suite at the Equinox Hotel at Hudson Yards but gave no indication of what was in store. After two years without live press events or audio shows, I was not going to spurn the offer no matter what would be presented: I was hungry for hi-fi. Upon arrival, I learned that Marantz would be featuring just one new product, a streaming integrated amplifier, the Marantz Model 40n ($2499). Sure, I'm in.

Characteristically, the email from Kal Rubinson got straight to the point: "I have a WiiM Mini that I have played with, but I am not the right one to review this as I am not sufficiently interested in or knowledgeable about wireless streaming. It ... can handle uncompressed PCM via its DACs." "I'll review it," I replied, intrigued by a $99 D/A processor that can stream hi-rez audio via Wi-Fi and that also has an analog input so it can act as a preamplifier.

Melco, the Japanese maker of the N50 Music Library featured in this review, is not a household name among US audiophiles. Veterans may recall the Melco 3560 turntable, which was considered extravagant at its 1978 launch, in part because it supported three tonearms. Confusingly, several subsidiaries of the giant keiretsu Mitsubishi are called MELCO (for "Mitsubishi Electric Corporation"), but the maker of the N50 is not one of those MELCOs. This "Melco" is, rather, short for "Maki Engineering Laboratory Company," and though it got its start in hi-fi, these days its best-known products are network-attached RAID arrays made by Melco's American division, Buffalo Americas.

Ah, domesticity. Just when I had the reference system sounding better than ever, the husband decided to relocate his electric keyboard and music stand, which had been positioned along the right wall of the detached music room, to the dining room in the main house. His reason was rational: While I did the reviewer thing in one space, he'd be free to practice keyboard and sing in another. But what was rational to him screwed with my reference sound and drove me to the brink of irrationality.

I start this review with a confession. I have consistently found that when I play CDs on a transport and feed the digital data via AES3 (AES/EBU) to a D/A processor, the music has more drive, particularly at low frequencies, than it does when I send the same 16/44.1 data to the same D/A processor via my network.

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."

On the face of it, playing and streaming digital music files is a straightforward process. You direct data from various sources—some local, some "in the cloud"—perhaps via a reclocker/signal conditioner to a digital-to-analog converter (DAC). "And the music comes out here."

Not so simple. Bits, it seems, aren't bits, or not only. A digital datastream is also an analog signal. Noise and other signal errors endemic to multi-function computers not designed primarily for music playback can affect how music sounds. And then there are the practical issues of setting up and connecting everything optimally, and then organizing music files correctly, which can be especially difficult when ripping files from multidisc sets.
