Product Description

Innuos Zen MK III

Streaming Music Server

innuos zen mk 3


Innuos designs a range of streaming products for both audio and video in the UK an builds them in Portugal, a range that contains three Zen models of audio server with a built in disc drive. The Zen MkII is the middle model in the line between the Zen Mini below, and the ZENith MK III and Zenith Statement higher up. The ZEN is an enthusiast level audio component with a number of improvements over the ZENmini.

Linear Power Supply

The ZEN uses a linear power supply design with ultra-low noise regulators (40 uV), specialized Nichicon MUSE audio capacitors and a medical-grade power filter to ensure sonic transparency.

Ultra-low Noise Ethernet Input & Streamer Output

The Zen has Dual-ethernet ports with isolation transformers to filter noise significantly improve sound quality. One for the incoming data on ethernet, and the other for connected streamers. You can bypass your router and connect an additional streamer directly to the Zen via the second ethernet port, which offers up a much quieter signal when compared to a direct router connection.

Reduced Vibration

Vibration kills good sound quality so Innuos has added significant anti-vibration treatment to the chassis and  internal electronic components.

In-Memory Playback

With 2GB dedicated memory, the ZEN loads music directly to memory for playback so that it doesn’t need to engage the hard drive, improving sound quality.

 "All in all the Innuos Zen MkII makes a very good case for using a dedicated audio server rather than a NAS drive and network switch, it sounds considerably better for one, making even a high end NAS seem distinctly crude by comparison. It also gives excellent results with both USB and Ethernet connections thanks to the efforts that the company has put into creating a quiet power supply and well isolated outputs."
