iFi Audio ZEN One Signature DAC

ZEN One Signature Universal DAC, by iFi Audio.

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

The result? A seriously 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.

ZEN One Signature is the first ZEN DAC to support all hi-res: DSD256, PCM384, MQA384kHz, Bluetooth 96KHz. Purity of design, no headphone amp, no volume control. The ultimate DAC for all your home audio sources.

The next-generation HD Bluetooth technology in the ZEN One Signature ensures the best sound from every source. Extensive high-definition codec support – aptX HD, aptX Adaptive, LDAC and HWA/LHDC. High-gain antenna delivers extended Bluetooth range. ifi Audio think you will love it, and we can't help but agree.

Balanced circuitry is what the ZEN series is famed for. The ZEN One Signature continues the tradition, featuring a balanced circuit design with Signature-grade circuit component, delivering ultra-low distortion and exceptional sonic purity via 4 mm Balanced and RCA single-ended analogue outputs – allowing connection to an integrated amp, preamp, headphone amp or active speakers.
