The ZEN CAN Signature 6XX pushed this design even further with sonic tailoring specific to the ‘MassDrop x Sennheiser HD 6XX headphone’.\nNow, iFi has finely tuned a brand new ZEN CAN Signature to work with HIFIMAN headphones – the ZEN CAN Signature HFM.\niFi’s ActivEQ\nOur 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 analog domain without adding any additional noise or distortion.\nHIFIMAN 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.\nOne EQ. Many models.\nPressing the HFM button on the ZEN CAN Signature HFM calibrates its signal to complement the headphone’s response characteristics right across the frequency range. This then tunes its performance to work with HIFIMAN headphones.\nExcellent results are found with the Sundara, HE-4XX, HE-400S, Edition X, HE-5 headphones to name but a few. As with our previous ZEN CAN Signature model, this feature can be switched on or off. Without ActivEQ engaged, the ZEN CAN Signature HFM’s performance is cleverly balanced to bring out the best in all other headphones and in-ear monitors.\nGain, gain, and more gain\nThe ZEN CAN Signature HFM has four gain settings in six dB steps – 0dB, 6dB, 12dB and 18db. We’ve called this PowerMatch. This enables the amp to precisely suit the connected headphones. Unity gain (0dB) is useful to ensure low noise with sensitive in-ear monitors, while the higher gain settings make the most of tougher headphone loads, delivering excellent dynamic headroom.\nNothing beats Balanced\nThe ZEN CAN Signature HFM’s circuitry i","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-ifi-headphone-dac-amp-ifi-zen-can-signature-hfm-apos-certified-38522426065132.jpg?v=1741112320","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-ifi-headphone-dac-amp-ifi-zen-can-signature-hfm-apos-certified-38522300891372.jpg?v=1741112320","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-ifi-headphone-dac-amp-ifi-zen-can-signature-hfm-apos-certified-38522300629228.jpg?v=1741112320","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-ifi-headphone-dac-amp-ifi-zen-can-signature-hfm-apos-certified-38522300661996.jpg?v=1741112321","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-ifi-headphone-dac-amp-ifi-zen-can-signature-hfm-apos-certified-38522300694764.jpg?v=1741112321","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-ifi-headphone-dac-amp-ifi-zen-can-signature-hfm-apos-certified-38522300727532.jpg?v=1741112321","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-ifi-headphone-dac-amp-ifi-zen-can-signature-hfm-apos-certified-38522300760300.jpg?v=1741112321","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-ifi-headphone-dac-amp-ifi-zen-can-signature-hfm-apos-certified-38522300793068.jpg?v=1741112321","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-ifi-headphone-dac-amp-ifi-zen-can-signature-hfm-apos-certified-38522300825836.jpg?v=1741112321","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-ifi-headphone-dac-amp-ifi-zen-can-signature-hfm-apos-certified-38522300858604.jpg?v=1741112321","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-ifi-headphone-dac-amp-ifi-zen-can-signature-hfm-apos-certified-38522300924140.jpg?v=1741112321","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-ifi-headphone-dac-amp-ifi-zen-can-signature-hfm-apos-certified-38522300956908.jpg?v=1741112321","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-ifi-headphone-dac-amp-ifi-zen-can-signature-hfm-apos-certified-38522300989676.jpg?v=1741112321","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-ifi-headphone-dac-amp-ifi-zen-can-signature-hfm-apos-certified-38522301022444.jpg?v=1741112322","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-ifi-headphone-dac-amp-ifi-zen-can-signature-hfm-apos-certified-38522301055212.jpg?v=1741112322","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-ifi-headphone-dac-amp-ifi-zen-can-signature-hfm-apos-certified-38522301087980.jpg?v=1741112322","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-ifi-headphone-dac-amp-ifi-zen-can-signature-hfm-apos-certified-38522301120748.jpg?v=1741112322"],"price":224.25,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:59.629Z"},"share_url":"https://firestarter.network/l/lst_hm2EmN2Y","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
