iFi Zen Can Signature 6XX Headphone Amplifier

The ZEN CAN Signature 6XX builds upon iFi’s acclaimed Zen Can amplifier, introducing enhancements in circuit design and a tailored EQ setting for optimal performance with the popular MassDrop x Sennheiser HD 6XX headphones. Drawing from the flagship Pro iCAN’s Class A discrete balanced circuitry, this amp delivers power, precision, and versatility for various headphones, including high-impedance models.

Key Features

Powerful Output

• 15.1V at 300 Ohms provides ample power to drive challenging headphones with ease.
• Delivers 1600mW into 32 Ohms, ensuring dynamic performance across the spectrum.

Class A Circuitry

• Derived from the flagship Pro iCAN, it includes a discrete output buffer and Op-Amp OV2637A for ultra-low distortion.
• Features a FET input to minimize volume control loading, ensuring clean signal integrity.

Versatile Gain Settings

• Four selectable steps: 0dB, 6dB, 12dB, and 18dB.
• Unity gain (0dB) suits sensitive in-ear monitors, while higher gains power demanding planar or high-impedance headphones.

Inputs and Outputs

• Inputs: RCA stereo, 3.5mm single-ended, and 4.4mm Pentaconn balanced.
• Outputs: 4.4mm balanced headphone, 6.3mm single-ended headphone, and a balanced 4.4mm line output for connecting to power amps.

ActivEQ for Sennheiser HD 6XX and Beyond

The ZEN CAN Signature 6XX features ActivEQ, which customizes the frequency response for the MassDrop x Sennheiser HD 6XX headphones. This analogue-domain EQ enhances bass and treble balance while preserving the renowned midrange quality of the HD 6XX and compatible models like the HD 650.

• XSpace Mode: Expands the soundstage, creating a more speaker-like listening experience by mitigating the “in-head localization” common with headphones.
• The EQ curve can be toggled on/off, offering flexibility for use with other headphones or in-ear monitors.

Performance and Specs

• Signal-to-Noise Ratio (SNR): 122dB (Balanced) for ultra-quiet operation.
• THD: 0.0066% (Balanced), 0.0058% (Single-Ended).
• Frequency Response: 10Hz – 200kHz (-3dB).
• Output Impedance: <2 Ohms (Balanced), <1 Ohm (Single-Ended).
• Weight/Dimensions: 1.87 lbs; 6.3" x 4.6" x 1.4".

Dynamic Duo with ZEN DAC Signature

Pairing the ZEN CAN Signature 6XX with the ZEN DAC Signature creates a cohesive, high-performance desktop setup for digital and analog sources. The ZEN Signature Set includes both units plus a premium 4.4mm Pentaconn cable for balanced connectivity.
