IFI - ZEN One Signature DAC

The Only DAC You’ll Need: iFi ZEN One Signature Is a Flexible Home Audio Hub for All Your Digital Devices
The world-class engineers at iFi have cooked up something extraordinary with the ZEN One Signature DAC. It 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 that can serve 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 game consoles.
The ZEN One Signature DAC specializes in high-resolution sound, offering full MQA decoding. This compact yet mighty component flexes its muscles as the first ZEN DAC to support DSD256, PCM384, MQA384kHz, and Bluetooth 96KHz. The sonic purity of its design and a fastidious focus on stellar sound means that there’s no headphone amp and no volume control. This is the ultimate DAC for all your home audio sources.
The iFi ZEN series is famous for its balanced circuitry, and the ZEN One Signature extends that tradition. Its balanced circuit design with Signature-grade circuit components are engineered to deliver ultra-low distortion and exceptional sonic purity. The 4mm balanced and RCA single-ended analog outputs allow you to connect to an integrated amplifier, a preamp, a headphone amp, or active loudspeakers.
The next-generation HD Bluetooth technology in the ZEN One Signature ensures that you will experience the best sound from every source. It offers extensive high-definition codec support — aptX HD, aptX Adaptive, LDAC, and HWA/LHDC. Additionally, the high-gain antenna delivers extended Bluetooth range.
"[The] ZEN One Signature proves itself as a very good home audio device from start to finish. Considering the competitive price and the clean output, I think this is one of the best all-in-one solutions from iFi."

Burr-Brown Chipset
The Burr-Brown “True Native” chipset means file formats remain unchanged, or “bit-perfect.” This allows you to hear music as the artist intended — in the format in which it was recorded. The iFi design team uses Burr-Brown extensively, having selected it for its natural-sounding “musicality” and “True Native” architecture.
MQA Decoding
MQA (Master Quality Authenticated) is an award-winning audio technology that enables music fans to stream reference-level recordings into their homes. Thanks to the processing power of the 16-core XMOS chip, the ZEN One Signature DAC performs full MQA decoding (to 384kHz).
