iFi audio ZEN CAN Signature 6XX Amp

The Sennheiser HD 6XX headphones are our all-time best-selling collab for a reason. Their sound is exceptional-and it's best when driven through a dedicated headphone amp. Enter the ZEN CAN Signature 6XX from iFi audio: an all-analog amp with a switchable EQ circuit specifically designed to get the most out of the HD 6XX. Called ActivEQ, this circuit calibrates the amp's signal to complement the HD 6XX's frequency response characteristics, thus tailoring its performance to precisely fit the headphones like a made-to-measure suit. What's more, ActivEQ does this without adding any of the distortion commonly associated with passive equalization circuits. Made with high-end circuit design and components taken out of the iFi's Pro range-including the Pro iCAN's Class A output stage-this compact amp can drive 15V / 750mW into 300 ohms with less than 0.0066% distortion, ideal for the 6XX. It's also outfitted with a range of flexible features-including adjustable gain, great for dialing in other headphone models-the ZEN CAN Signature 6XX is a truly transcendent headphone amp, at a down-to-earth price.
