- 2ZEN DAC Signature V2
- 3ZEN CAN Signature 6XX Headphone Amp
- 44.4mm Balanced Cable
Audiophiles and music enthusiasts looking for an affordable yet high-quality desktop headphone system tailored for their Sennheiser HD 650 or HD 6XX headphones will be thrilled with the ZEN Signature Set 6XX from iFi audio, which includes a ZEN DAC Signature V2 portable USB digital-to-analog converter, a ZEN CAN Signature 6XX headphone amplifier, and a high-quality 4.4mm balanced cable to connect the two devices.
The ZEN DAC Signature V2 features a balanced 4.4mm output and a set of unbalanced stereo RCA outputs. The upgraded XMOS chipset features 16 cores to power the digital engine, while the updated clock circuitry reduces jitter, which provides 20 dB of better noise reduction. Audiophile components are used throughout�including C0G capacitors from TDK�with Panasonic OS-CON and ELNA Slimic II capacitors completing the design. The ZEN DAC Signature V2 includes MQA technology, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording.
The ZEN CAN Signature 6XX Headphone Amp uses completely balanced analog circuitry to drive a wide variety of headphone models and offers ActiveEQ, a customized EQ curve designed to complement the Sennheiser HD 650 and MassDrop x Sennheiser HD 6XX headphones.
Power supplies, a stereo RCA cable, and a USB cable are also included.
ZEN DAC Signature V2
- The ZEN DAC Signature V2 is a pure DAC and benefits from true-differential balanced circuit design to take performance to the next level. It has upgraded circuit components and short, direct signal paths for optimal signal purity.
- The unit delivers bit-perfect PCM (up to 32-bit/384kHz), native DSD (up to DSD256), DXD and MQA.
- A pair of RCA sockets allows for single-ended connection to an amp, plus a balanced 4.4mm output is also provided. When connected to an amp or active speakers equipped with a balanced input�either a 4.4mm Balanced input, or stereo XLR inputs via a 4.4mm-to-XLR cable�the full benefit of the ZEN DAC Signature V2�s balanced circuit design can be heard.
- Its outputs can be switched between variable and fixed.
ZEN CAN Signature 6XX Headphone Amp
- The ZEN CAN Signature 6XX improves the sound quality of the original ZEN CAN and adds a unique feature, a custom EQ setting called ActivEQ; this combines active and passive components to create a specific EQ curve to suit the Sennheiser HD 650 and MassDrop x Sennheiser HD 6XX headphones.
- ActivEQ can be switched off to make the most of all manner of headphones and in-ear monitors. The amp also features XSpace, an analog processing mode that compensates for the in-head localization effect that can occur when using headphones to listen to music that was mixed using a pair of speakers.
- Four gain settings in six dB steps are available: 0 dB, 6 dB, 12 dB, and 18 db.
- 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.
- The amp offers stereo RCA and 3.5mm single-ended inputs, plus a 4.4mm balanced input. A 4.4mm balanced output is also provided. The unit also has a 1/4" output for headphones that have a standard single-ended connector and a 4.4mm balanced output for headphones offering a balanced connection.
4.4mm Balanced Cable
- The iFi 4.4mm balanced cable employs heavy OFHC continuous cast copper and silver matrix conductors with a total thickness of 14 AWG for the best signal transfer.
- A perfect addition to the ZEN Signature Set 6XX, this audiophile-grade cable will give you maximum quality balanced signal transfer and minimum interference.
- The cable construction is a custom helix design, minimized both in capacitance and inductance. The intrinsic shielding provided by minZ helix construction protects the cable from RFI and EMI noise and provides the cleanest transfer medium possible.
- An RoHS compliant, super-soft (60P) HD polymer with 1500V AC spark resistance and excellent dielectric properties further insulates the cable.
