Introducing the ZEN CAN The TL; DR The iFi audio ZEN CAN is a fully symmetric dual-mono headphone amp based on our Pro iCAN’s circuit, with latest 4.4mm Pentaconn connections on input and output, and in-built 3D and XBass analogue signal circuits.
Topology iFi audio ZEN CAN’s amplification circuit is the same as used in Pro iCAN. It features a balanced discrete Class A output buffer combined with a J-FET Op-Amp (OV2637A). Its FET input doesn’t load volume control, which means exceptionally low distortion/noise, whereas low impedance feedback enhances overall performance and avoids resistor noise.

MCU optimisations To keep noise contamination to an absolute minimum, the ZEN CAN’s MCU (a microcontroller unit to manage key functions of the product) and LEDs are in ‘wake mode’ only when actioned. Otherwise they’re put into ‘sleep mode’, even during listening to music. All switches inside the product are FET-based for full sonic transparency, ability to handle enormously high peak signals, and distortion/ noise levels below Audio Precision 2’s measurements.

To further reduce noise, and have excellent transient response and PSRR performance (rejection of power supply noise), the iFi audio ZEN CAN features Bipolar CMOS (BiCMOS) semiconductor technology, which integrates two separate semiconductor types and makes the best of them.

A four-wire balanced connection eliminates this issue completely. The iFi audio ZEN CAN’s balanced circuitry completely separates both channels, and its line inputs will work with balanced output sources and professional equipment. It features Pentaconn connector type because off its high-quality build and low contact resistance.

Any external power supply able to provide DC 5V/2.5A will work. For optimal results please use our iPower X/iPower. If USB outputs in your computer/laptop are within listed specs, it's possible to power the ZEN CAN from these ports as well, and thus avoid the usage of external power supply.

How do I use the ZEN CAN's inputs? Please connect a cable of choice from your DAC to the ZEN CAN's suitable input, and engage via the input selector button on the product's front. Single-ended cables will work with 3.5mm and RCA inputs, whereas a balanced cable will work with 4.4mm Pentaconn input.

Use the lowest gain setting that gives you a good comfortable listening level with the volume control at around 12 o'clock. If you can’t go higher in volume as music becomes too loud before reaching 12 o'clock at the lowest gain setting, you may want to test the iFi iEMatch product to see if this helps to match your headphones better to the ZEN CAN’s headphone output.

What kind of cables I need to get the best out of the ZEN CAN? The ZEN CAN works well with standard RCA cables, but to get the very best out of it, you'll need to use the 4.4mm Pentaconn input on its rear.
