Main Features


Triple-Linear Power Supply

Inspired from the high-end power supply engineering of the SE, ZENith Mk3 benefits from new premium Mundorf capacitors with ultra-low noise regulators and a medical-grade mains filter to provide even greater audio clarity.


Custom Motherboard

Our own custom-made Innuos motherboard is completely reworked for optimised audio performance. Sources of EMI have been removed, 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 and EMI Treatment

New asymmetrical isolation feet derived from our ZENith SE plus added treatment to the chassis help to combat harmful vibration that affect a clean audio signal, with even greater treatment now applied to the SSD.


In-Memory Playback

With 4GB dedicated memory, ZENith loads music directly to memory for playback so that it doesn’t need to engage the SSD during playback, improving sound quality.


MQA Core Decoding

ZENith 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. ZENith can also passthrough MQA files to MQA Full Decoder DACs.

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