The ZEN is a true HiFi component with a number of improvements on top of the ones offered by the ZENmini.

Linear Power Supply

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

Ultra-low Noise Streamer Output

Dual-ethernet ports with isolation transformers on Ethernet ports significantly improve sound quality on streamers when compared to a direct router connection.

Reduced Vibration

Vibration kills good sound quality so we have added significant anti-vibration treatment to chassis and 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 during playback, improving sound quality.
