Cayin HA-3A Vacuum Tube Headphone Amplifier

Engineering meets Aesthetics
The HA-3A represents exquisite design accomplished by first class engineering – aesthetics backed up by genuine production quality. The HA-3A vacuum tube headphone amplifier is built so you can listen favorite music through your choice of headphones, and escape into a private, indulging retreat.

HA-3A might look compact and simple, but Cayin has devoted our renowned engineering and decades of audio equipment manufacturing to combine carefully selected, high-performance components to make it happen.

Clean Power with Minimum Interference
HA-3A users the renowned RCA 25AX4GT as a rectifier tube. The rectifier converts the incoming power souce to DC current and the RCA 25AX4GT does this while minimizing interference and providing clean power to the amplification circuit. Accompanying the RCA 25AX4GT Rectifier are dual matched JJ 12AU7/ECC82 in the driver stage, and dual EHX 6V6GT for the output stage.

Transformer-coupled, Balanced Drive
The 6V6 output drivers a pair of proprietary output transformers that support single-ended and balanced headphone outputs. The secondary winding of the output transformer provides the alternate phase needed for a balanced output, enabling balanced power from a single-ended origin.
