The ZEN CAN Signature 6XX improves the sound quality of the original ZEN CAN and adds something special – a custom EQ setting called ActivEQ. It combines active and passive components to create a specific EQ curve to suit the ‘MassDrop x Sennheiser HD 6XX’ headphones.
This can be switched off to make the most of all manner of headphones and in-ear monitors. It also features XSpace – an analogue processing mode which 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 features four gain settings in six dB steps – 0dB, 6dB, 12dB and 18db.
The ZEN CAN Signature 6XX’s circuitry is a balanced, symmetrical dual-mono design. It delivers 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.
It offers stereo RCA and 3.5mm single-ended inputs, plus a balanced 4.4mm Pentaconn input. A 4.4mm balanced output is also provided. It has a 6.3mm output for headphones that have a standard single-ended connector and a 4.4mm Pentaconn balanced output for headphones offering a balanced connection.

The iFi 4.4mm to 4.4mm cable employs heavy OFHC continuous cast copper and silver matrix conductors with a total thickness of 14AWG for the best signal transfer.
It’s a perfect addition to our ZEN Signature Set 6XX as this audiophile-grade cable will give you maximum quality balanced signal transfer and minimum interference.
The cable construction is a custom helix design, minimised both in capacitance and inductance, minZ™.
It also has intrinsic shielding provided by minZ™ helix construction. They protect the cable from RFI and EMI noise and provide the cleanest transfer medium possible.
To further insulate the cable, we adopted the RoHS compliant, excellent dielectric property and super-soft (60P) HD polymer with 1500V AC spark resistance.
