Active 'v' Passive Speakers

So, what’s the difference?

Active speakers have an in-built power amplifier and just need a power cable (or battery) to operate. Passive speakers require an external power amplifier to operate.

In short, you need an amplifier for passive speakers, you don’t with active speakers.

ZEN CAN — the ultra-affordable headphone amp from iFi audio
Nitro for your headphones.

Fully-balanced. 1,600mW. Battleship headphone amplifier.

52x more power. Pump up the volume.

Laptops and smartphones have a really low power output of <1.0v. On a good set of headphones you’re always running out of juice. You never get to really hear what they can do.

Use a laptop, phone or DAC to feed your music to the ZEN CAN and connect your headphones. Pumping out 52x more power, now you’ll hear what you have been missing.

Balanced to thrill

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

Puts you at the venue. Not other way round.

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.

Our 3D special sound circuit solves this:

  • Stereo image that is truly out of your head, in front with height, width & depth
  • Without colouration or loss of resolution
  • All analogue circuitry (i.e. without costly and complex digital signal manipulation)

Satisfies all listeners.

Ace of XBass

Behind XBass is our active EQ circuit which meets a common gripe with headphones head-on, a lack of bass.

Open-back headphones in particular, let all frequencies (especially those precious bass frequencies that the drivers generate so little of) leak freely out of the back instead of trapping and redirecting them back to your ears.

XBass equalisation is a much more elegant solution to bass correction than seen elsewhere. It consists of active and passive components and its frequency response curve corrects their low-end response problems with precision.

Packed with premium goodness

Underpinning the Balanced and Active EQ circuitry are:

  • Panasonic ECPU capacitors
  • TDK C0G (Class 1) ceramic capacitors
  • iFi/AMR ‘OV’ ‘Operationsverstärker’ series op-amps
  • MELF resistors
  • Texas Instruments low-noise ICs
  • muRata capacitors and
  • Tokyo Cosmos Electric Co. (TOCOS) multi-track potentiometer, with exceptional channel matching even at low volume

52x

more headphone power

A fully-discrete and balanced amplifier audio circuit. The full symmetric dual-mono headphone amplifier with gold-plated 4.4mm balanced connection. Premium engineering is more expensive but lowers the noise floor to a whisper-quiet levels.

Check out the tech note for the details.

Class A Discrete is a circuit that has come straight out of the iFi’s flagship headphone amplifier, the Pro iCAN, which at £1,699 is 11 times the price of the ZEN CAN.

As with many other iFi audio products, we’ve incorporated a custom OV Series operational-amplifier. This top-notch component contributes to the extremely low noise, low distortion (0.0001%) and wide bandwidth.

TDK C0G (Class 1 ceramic) capacitors offer high stability and low losses for resonant circuit applications. They are pricey but are a perfect addition to our products.

Sonically superior – richer, deeper.

The XBass® analogue bass correction system corrects for the missing headphone/speaker bass response.

An ‘Out of Head’ listening experience. Our 3D Holographic® dual-analogue matrices place the artist with you in the room, not inside your head.
