The ZEN One Signature is an all-in-one hub for all your wired and wireless hi-res audio. ZEN One Signature is the only desktop DAC you'll ever need, taking the DAC stage from the ZEN DAC V2, then adding S/PDIF inputs (optical & coaxial) alongside the USB port. ZEN One Signature also inherits the Bluetooth receiver tech from the ZEN Blue V2, and seasons the pot with Signature-grade circuit enhancements to create a delicious audio brew.

The ZEN One Signature is a pure DAC (no built-in headphone amp and volume control) that serves as a home audio hub for all your digital devices, from smartphones and tablets to PCs and Macs, disc players, and audio servers to TVs and games consoles.


Home Hub & Hi-Res DAC

  • USB audio using 16-core 2000MIPS XMOS low latency microcontroller chip.
