The ZEN MK3 provides another leap into sound quality compared to the ZENmini with its integrated dual-linear PSU, isolated dual-ethernet ports and asymmetrical anti-vibration feet. The ZEN MK3 represents new value for money in digital audio performance.

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. 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. 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. 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. 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.
