iFi Audio ZEN CAN Signature HFM Amp

The right amp can really make a pair of high-end headphones shine—and what’s more right than a headphone amp that’s literally designed for your specific pair of headphones? The iFi ZEN Can Signature HFM Amp is part of iFi’s line of amps designed to accentuate all the best qualities of a specific pair of cans—with the HFM indicating this particular amp’s focus on HIFIMAN headphones. Matched ideally for a wide array of models including the Sundara, the HE-4XX and more, the HFM amp sports a eponymously named HFM button that triggers the amp’s ActivEQ function—which, in this case, deepens the bass texture and sharpens the upper mid-range. You’ll find impressive circuitry at play throughout the HFM Amp, delivering an incredibly low 0.006% total harmonic distortion on the balanced output, a signal-to-noise ratio as high as 121 decibels, and a far-reaching frequency response that covers well beyond the spectrum of human hearing. It is truly the height of HIFIMAN-accentuating headphone amplifiers.
