iFi Audio Zen DAC Signature is a desktop DAC unit that’s designed to feed a headphone amp, or an amp and speakers with jitter-free clean audio, which also support hi-res audio for streaming from services such as tidal.
Why the Signature?
iFi Audio’s current Zen DAC model uses a fully balanced circuit design, but the Zen DAC Signature has an enhanced true-differential balanced topology with improved circuitry to provide short, direct signal paths for better signal purity, which results in more detailed sonic expression.
This simplified circuitry also allows the signal path and components to be upgraded, if you so wish.
Fixed or Variable
The ZEN DAC Signature’s outputs can be switched between a ‘variable’ and ‘fixed’ mode. The variable mode sets volume control to the audio signal, which makes the Zen DAC Signature act as a preamp. The fixed mode bypasses the volume control, fixing the output at 4.2V (balanced) or 2.1V (single-ended) for connection to an external preamp, integrated amp or active speakers.
The Zen DAC Signature has a USB Type B input that supports USB 3.0, as well as USB 2.0; the asynchronous design provides accurate, jitter-free data transfer from the source device.
A pair of RCA sockets is built-in for single-ended connection to an amp, plus a Pentaconn 4.4mm output to enable balanced signal transfer between products that do not have XLR connections.
iFi Audio’s Zen DAC Signature supports hi-res audio for audio streaming services such as TIDAL; it delivers bit-perfect PCM (up to 32-bit/384kHz), native DSD (up to DSD256), DXD and MQA.
