Do you love your Hifiman headphones? Then the ZEN CAN Signature HFM analog headphone amplifier is just right for you. iFi Audio has optimized the ZEN CAN Signature for seamless interaction with Hifiman headphones to bring out the best in these already remarkable headphones. The ActivEQ feature combines active and passive components to create a specific EQ curve for a particular headphone. This is done in the analog domain without additional noise or distortion. The ZEN CAN Signature HFM features an ActivEQ specifically tuned for Hifiman's planar magnetic headphones. Hifiman headphones are known for their remarkable transparency and expansive soundstage. The ZEN CAN Signature HFM enhances the texture of the deep bass and adds more presence to the upper midrange. By pressing the HFM button on the ZEN CAN Signature HFM, the signal is calibrated to complement the headphone's frequency response across the entire frequency range. This optimizes the device's performance for collaboration with Hifiman headphones. The ActivEQ function can be turned on or off. When ActivEQ is not activated, the performance of the ZEN CAN Signature HFM is cleverly balanced to extract the best from all other headphones and in-ear monitors. The circuitry of the ZEN CAN Signature HFM features a symmetrical dual-mono design—a topology typically reserved for high-end headphone amplifiers. The amplifier delivers excellent drive performance of 1600 mW (7.2 V) at 32 ohms via the unbalanced output and over 15V at loads of 600 ohms or more via the balanced output. The ZEN CAN Signature HFM is characterized by extremely low distortion, high detail richness, and plenty of dynamics, as well as the ability to drive all types of headphones with ease. It is a force of nature.
