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.


MQA Core Decoding

ZEN supports MQA Core Software Decoding, which means you can playback MQA audio files and streams, delivering the sound of the original master recording. MQA Core software decoding is provided free of charge and enables streaming and playback of MQA files up to 24bit/96 kHz for non-MQA DACs and up to 24bit/384 kHz for MQA Renderer/Decoder DACs. ZEN can also passthrough MQA files to MQA Full Decoder DACs.

InnuOS Operating System 2.3 or higher is required for MQA Core Decoding.
