ZEN Mk3
Dual-Linear Power Supply
The ZEN ensures a cleaner digital signal by reducing power noise. Through a dual-linear power supply, designed by Dr. Sean Jacobs, with ultra-low noise regulator design, Nichicon MUSE Capacitors and medical-grade mains filter, your music opens up and reveals new levels of realism.
Custom Motherboard
Our own custom-made Innuos motherboard is completely reworked for optimised audio performance. Sources of EMI have been removed and internal clocks optimised, resulting in a “blacker” music background and enhanced realism.
Ultra-low Noise Streamer Output
Dual-ethernet ports with isolation transformers provide an ultra-low noise network connection for your streamer, removing noise from the path and improving sound quality on all network audio.
Anti-vibration Treatment
New asymmetrical isolation feet derived from our award-winning ZENith SE plus added chassis treatment help to combat harmful vibration that affect a clean audio signal.
In-Memory Playback
Now with twice the memory of the Zen Mk2, the Zen MK3 has 8GB RAM with 4GB dedicated memory. Music is loaded directly to memory for playback so that it doesn’t engage the hard drive, improving sound quality.

Reviews
Innuos Zen MK3 Music Server
``There are many companies that offer music servers, often based on standard motherboards and run-of-the-mill housings. Innuos is not one of those. They use their own motherboard, housing and firmware, all designed for low noise - both acoustically and electrically. And it’s versatile, does LMS, UPnP, Sonos and Roon. Yep, also Roon Core.``
