DesignTechnica reviews the high-end music server from ReQuest Multimedia.

"ReQuest Multimedia’s Nitro music server is a hard drive-based audio player worthy of a prominent spot in any high-end audio rack or home theater. It does everything that you could want an audio player to do and it looks good doing it.

With a highly evolved interface, advanced control options, and CD quality audio, the Nitro Pro should help the late-adopters appreciate the benefits of truly digital music, and satisfy those on the bleeding edge of technology.
If you’re one of the lucky consumers that can justify the $2,500 price tag of the Nitro Pro music server, we recommend the product without hesitation. "
