iFi – Zen Dac Signature – USB Dac


Categories: ,


Enveloped in the Space Blue finish now associated with iFi Signature products, the ZEN DAC Signature has been designed to be a USB DAC, pure and simple.

Without the built-in headphone amp, its sole purpose is to feed an external amp, be it a headphone amp, or an amp and speakers.

Its simplified circuitry provides the opportunity to upgrade the signal path and critical components within it. The existing ZEN DAC introduced the benefits of fully balanced circuit design but the ZEN DAC Signature further ups the ante with its enhanced true-differential balanced topology.
