iFi audio ZEN CAN Signature HFM (2021) Headphone Amplifier designed for HIFIMAN planar headphones

Finely tuned.
The original ZEN CAN, our all-analogue headphone amplifier, had the ability to drive tough headphone loads with a balanced circuit design, vanishingly low levels of distortion and exceptional sonics. The ZEN CAN Signature 6XX pushed this design even further with sonic tailoring specific to the ??assDrop x Sennheiser HD 6XX headphone??
Now, we??e finely tuned a brand new ZEN CAN Signature to work with HIFIMAN headphones ??the ZEN CAN Signature HFM.
This custom ActivEQ setting is expertly tuned across the entire frequency response curve to bring out the best in these already remarkable headphones.

iFi?? ActivEQ
Our ActivEQ feature combines active and passive components to create a specific EQ curve to suit a particular pair of headphones. This is performed in the analogue domain without adding any additional noise or distortion.
The ZEN CAN Signature HFM features an ActivEQ finely tuned towards HIFIMAN?? planar headphones.
HIFIMAN headphones offer remarkable transparency and present wide-open sound staging. The ZEN CAN Signature HFM enhances the texture of the deep bass and injects more immediacy into the upper mid-range.

One EQ. Many models.
Pressing the HFM button on the ZEN CAN Signature HFM calibrates its signal to complement the headphone?? response characteristics right across the frequency range. This then tunes its performance to work with HIFIMAN headphones.
Excellent results are found with the Sundara, HE-4XX, HE-400S, Edition X, HE-5 headphones to name but a few. Take a look at our HIFIMAN Curve and Compatibility chart.
As with our previous ZEN CAN Signature model, this feature can be switched on or off. Without ActivEQ engaged, the ZEN CAN Signature HFM?? performance is cleverly balanced to bring out the best in all other headphones and in-ear monitors.
