High-quality DA converter with bluetooth receiver

Our ZEN One Signature takes the DAC stage from the ZEN DAC V2 , adds S/PDIF inputs (optical and coaxial) alongside the USB port, stirs in Bluetooth technology from the ZEN Blue V2 and seasons the pot with Signature-grade circuit enhancements to create a Delicious audio brew.

The result? 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.
