Pure performance.

Our specialist ZEN DAC Signature is designed to be a pure desktop DAC that takes no prisoners when it comes to performance.

Pure and (not so) simple.

Enveloped in the Space Blue finish now associated with our Signature products, the ZEN DAC Signature has been designed to be a 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.

Superior circuits. Superb sound.

Various key surface-mounted circuit components have been upgraded to high-end devices, including Panasonic OS-CON and Elna Silmic II capacitors.

The circuit has been refined to ensure short, direct signal paths for optimal signal purity. This results in even greater sonic detail and expression.

A true native…

The ZEN DAC Signature’s digital stage retains the True Native DAC architecture much loved here at iFi as well as

It delivers bit-perfect PCM (up to 32-bit/384kHz), native DSD (up to DSD256), DXD and MQA – the hi-res streaming codec, as used by Tidal’s ‘Masters’ tier. The sample rate of incoming audio data is indicated by a multicoloured LED residing behind the aluminium volume control.

The iFi-programmed XMOS chip, which processes data received at the USB input, and jitter-eradicating, audiophile-grade oscillators, contribute to exemplary handling of digital audio signals as they are received, processed and converted to analogue form.

Soul connections

The USB Type B input supports the ‘SuperSpeed’ USB 3.0 standard, as well as USB 2.0 for backwards compatibility. It is asynchronous, meaning that the data rate is regulated solely by the ZEN DAC Signature’s specialised audio clock circuitry for accurate, jitter-free data transfer from the source device.

There is a pair of RCA sockets for single-ended connection to an amp, plus a Pentaconn 4.4mm output – this enables balanced signal transfer between compact products that cannot accommodate traditional, bulky XLR connections.

When connected to an amp or active speakers equipped with a balanced input – either a 4.4mm Pentaconn input, or stereo XLR inputs via a 4.4mm-to-XLR cable – the full benefit of the ZEN DAC Signature’s balanced circuit design can be heard. It will speak to your soul.

Fixed or variable. You decide.

The ZEN DAC Signature’s outputs can be switched between ‘variable’ and ‘fixed’.

The variable setting applies volume control to the audio signal, enabling the ZEN DAC Signature to act as a preamp to connect directly to a power amp.

The fixed option 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 with their own volume control.

Dynamic Duo

The ZEN DAC Signature works well with the ZEN CAN Signature 6XX. 

When used in tandem, the two ZEN Signatures make a fantastic, desktop-sized headphone system for both digital and analogue sources, further extending the reputation of iFi’s ZEN Series for delivering exceptional performance and versatility at remarkable prices.

Additionally

  • The Burr-Brown True Native® chipset means file formats remain unchanged or ‘bit-perfect’. This means you are listening to music as the artist intended in the format in which it was recorded.
    At iFi we use Burr Brown extensively in our products having selected it for its natural-sounding ‘musicality’ and True Native architecture. Our experience with this IC means we know how to make the most of it.
  • Extensive jitter-eradication technologies are applied to the digital stage, including our GMT (Global Master Timing) femto-precision clock and intelligent memory buffer. This represents a total ‘out-of-the-box’ systematic digital solution that solves jitter once and for all.
  • Panasonic OS-CON caps totalling 5,410uF give very-low Equivalent Series Resistance (ESR), excellent noise reduction capability and frequency response characteristics. In addition, OS-CONs have a long life span and its ESR changes little even at low temperatures since the electrolyte is solid.
    They are not often found in products costing <US$1000.
  • Texas Instruments low-noise ICs offer great unity-gain bandwidth, very low noise and distortion, high output drive capability, Common-mode and Power Supply Rejection Ratios of over 100 dB, wide maximum-output-swing bandwidths and high slew rates.
  • A Tokyo Cosmos Electric Co. (TOCOS) multi-track potentiometer is used. This has close channel matching tolerance for optimal performance in quiet listening (low positions of pot).
  • muRata control-type, low-ESR high-Q multi-layer capacitors. The ‘ESR control’ aspect of the Murata is something special. Their noise suppression abilities are impressive.
  • We use ELNA Japan Silmic II capacitors for the power supplies.
    The primary constituent of the newly developed dielectric is silk fibre. This material was believed as unfathomable as an aluminium electrolytic capacitor. The new material beats silk fibre and mixes it with Manila hemp fibre to provide the dielectric to an aluminium electrolytic capacitor used for high-grade music. The result is second-to-none superior acoustic properties and excellent linearity.

Great version ZEN!

I bought with ZEN CAN Signature. I'm happy with the great sound.
