Level-up

The ZEN CAN has trickle-down Class A discrete balanced circuitry from iFi audio’s US$1,699 flagship Pro iCAN. With 15.1v @300 Ohms on tap, it has serious power that will make even difficult-to-drive headphones thump to the beat.

  • Class A discrete output buffer from the flagship Pro iCAN using Op-Amp (OV2637A)
  • FET input avoids loading volume control – low distortion/noise
  • SE inputs (1M Ohm) ensures loading of the source so always in Class A operation
  • Output amplifier gain of four steps in +6dB perfect for headphone matching

ZEN CAN Signature 6XX builds upon the outstanding Zen Can circuitry and takes it to another level. It further improves the sound quality with enhanced circuit design, whilst maintaining the versatile features of the ‘regular’ version and adding something special – a custom EQ setting precisely tailored across the entire frequency response curve to make the most of a popular headphone model. The Signature 6XX also offers stereo RCA and 3.5mm single-ended inputs, plus a balanced 4.4mm Pentaconn input. A 4.4mm balanced output is also provided, to connect to power amps equipped with a balanced input. It provides a pair of headphone outputs – a 6.3mm output for headphones that have a standard single-ended connector (compatible with all headphones) and a 4.4mm Pentaconn balanced output for headphones offering balanced connection. An increasing number of high-quality headphones and in-ear monitors either come so equipped or give the option of detaching the cable and upgrading to a 4.4mm Pentaconn connector, and this output makes the most of them (it is particularly recommended for high-impedance headphones).

ActivEQ

ActivEQ, combines active and passive components to create a specific EQ curve to suit a particular pair of headphones, performed in the analogue domain without a hint of additional noise or distortion.The ZEN CAN Signature 6XX, features ActivEQ for the ‘MassDrop x Sennheiser HD 6XX’ – a popular pair of high-quality headphones with more than 120,000 sold to date, based on the Sennheiser HD 650 and created exclusively for Drop.com. These headphones are renowned for the quality of their midrange performance but exhibit some quirks in the bass and treble regions, which can be seen in frequency response measurements.

Audio recordings are made for speakers and when played back on headphones, the sound is always driving you nuts by being only in your head. When the ‘HD 6XX’ button is pressed, the ZEN CAN Signature 6XX calibrates its signal to complement the headphone’s response characteristics right across the frequency range, thus tailoring its performance to precisely fit the HD 6XX like a made-to-measure suit.What’s more, the benefits of this ActivEQ curve are equally applicable to the Sennheiser HD 650, which shares the same characteristics, and other Sennheiser Models. This feature can be switched on or off. Without ActivEQ engaged, the ZEN CAN Signature 6XX’s performance is adroitly balanced to make the most of all manner of headphones and in-ear monitors. The XSpace analogue processing mode compensates for the ‘in-head localisation’ effect that can occur when using headphones to listen to music that was mixed using a pair of speakers. It widens the headphone soundstage to deliver a more spacious and speaker-like experience.

Driving force

ZEN CAN Signature 6XX features four gain settings in six dB steps – 0dB, 6dB, 12dB and 18db.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. The amp offers prodigious drive capability, delivering 1600mW (7.2V) into 32 ohms from the single-ended output, with 15V+ available to loads of 300 ohms or more through the balanced output, ensuring it takes even current-hungry planar headphones in its stride. Delivering ultra-low distortion, rich sonic detail, engaging dynamics and the ability to drive all manner of headphones with ease, the ZEN CAN Signature 6XX is a truly a driving force to be reckoned with.

Dynamic Duo

The ZEN CAN Signature 6XX works well with the ZEN DAC Signature. The two products can be bought separately but a ‘ZEN Signature Set’ is now available. This comprises both ZEN Signature units plus a high-performance 4.4mm Pentaconn cable to connect them together. When used in tandem, the two ZEN Signatures make a fantastic, desktop-sized headphone system for both digital and analogue sources, further extending the reputation of iFi’s ZEN Series for delivering exceptional performance and versatility at remarkable prices.
