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.

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.

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.
