iFi Audio ZEN CAN Signature Limited Edition Headphone Amplifier (Universal Version)

The original ZEN CAN, iFi's all-analogue headphone amplifier, excelled at driving demanding headphone loads with its balanced circuit design, extremely low distortion, and exceptional sonics. The ZEN CAN Signature takes this design further, featuring enhanced circuitry and audiophile-grade components.

Its balanced, symmetrical dual-mono circuitry can deliver 1890mW (11.0V) into 64-ohm loads and offer over 15V to loads of 600 ohms or higher, all through its balanced output.

After the popularity of the Sennheiser, Meze and HFM versions of the iFi Zen CAN Signature, iFi has released a limited edition universal version of the Zen CAN Signature with XBass designed for all brands of headphones. 

Laptops and smartphones typically have a low power output of less than 1.0V. With a quality pair of headphones, you often find yourself running out of power, never truly experiencing their full potential.

Connect your laptop, phone, or DAC to the ZEN CAN Signature and plug in your headphones. Delivering 50 times more power, you’ll finally hear what you’ve been missing.

However, the ZEN CAN Signature offers more than just power; it also delivers warm and exceptional sound quality. This is thanks to its Class A discrete balanced circuitry, inherited from the flagship Pro iCAN headphone amplifier.

The ZEN CAN Signature offers a range of input options, including stereo RCA, 3.5mm single-ended, and 4.4mm balanced inputs, making it versatile enough to connect with your laptops, phones, or DACs.

For output, it provides a 4.4mm balanced option for headphones that support balanced connections. It also features a 6.3mm jack for headphones with standard single-ended connectors. If you’re using earphones with a 3.5mm plug, a 3.5mm to 6.3mm adapter is available, so there’s no need to worry.

The unit also includes an analogue balanced output on the back panel, ideal for connecting active speakers via a 4.4mm to XLR adapter. As the ZEN CAN Signature is fully balanced and dual-mono circuit design, this is the recommended output option.

The ZEN CAN Signature offers multiple customisation options to suit a wide range of headphones.

Starting with PowerMatch, the unit provides four gain settings in six dB steps: 0dB, 6dB, 12dB, and 18dB. This feature ensures compatibility from super-sensitive IEMs to power-hungry headphones. We recommend starting at 0dB and then gradually adjusting the switchable gain level to find your optimal volume for both enjoyment and comfort.

It also features two analogue processing modes, XSpace and XBass, designed to enhance the soundstage and low-frequency response of your headphones. XBass tackles a common problem, particularly with open-back headphones: the loss of bass frequencies.

The ZEN CAN Signature employs a military-spec PCB to enhance signal integrity. It also incorporates audiophile-grade components, such as:

ELNA Silmic II and OS-CON capacitors offer excellent noise reduction capabilities and frequency characteristics.

iFi/AMR ‘OV’ ‘Operationsverstärker’ series op-amps provide low noise and distortion, delivering performance that equals or surpasses many high-end headphone amplifiers.

Unlike other headphone amplifiers that come with standard power supplies like those for notebooks, the ZEN CAN Signature includes the iFi iPower2 power supply. This features Active Noise Cancellation II to eliminate all incoming EMI and RFI noise, ensuring a clean and clear audio experience. The iPower2 is already exceptional, being more than 10 times quieter than standard power supplies. For those looking to further enhance their setup, consider the DC iPurifier2, which can further reduce system interference, as well as the iPowerX power supply.
