Cayin HA-6A | Desktop Tube Headphone Amplifier

Cayin HA-6A Brings Music to Life in Any Space


Transformer Coupled, Balanced Vacuum Tube Headphone Amplifier
Features 4-Pin, 4.4mm, and 6.3mm Headphones Outputs
Easy tube rolling and selectable output impedance for endless tonal options


Dual Operation Mode: Triode and Ultralinear
Change your sound signature with the flip of a switch, optimizing the presentation for different moods or styles of music. Triode mode offers a smooth sound with rich harmonics and lush, holographic imaging. Ultralinear Mode improves the dynamics and punch, with a clean authorative sound and enhanced extensive on both ends of the frequency spectrum.
Just Roll With It
HA-6A is built for tube rolling. The included EHX EL34 were hand selected by Cayin's engineers, but you can easily change the sound with different types of tubes to fully explore your tonal options. Combine easy tube rolling with selectable impedance for headphones ranging from 8-600 ohms, and the tonal options are endless.
Key Features
Impedance Matched Headphone Output: choose from Low, Medium, or High impedance to match your headphones
Optimized Headphone Outputs: the 4-pin XLR will provide the maximum power while the 4.4mm output allows for compatibility with high-end IEMs and more sensitive options.
60 second start up delay circuit: Protects your tubes and minimizes noise related to the warm up cycle of the amplifier

Incredible Craftsmanship and In-house design
The entire circuit is hand wired using point to point wiring, rather than a circuit board. Point to point, shortens the signal path and improves the efficiency and conductivity. Cayin also uses power transformers designed and wound in house, to ensure that the shielding and output is up to their standards. HA-6A's power transformers are a matched pair for further power and efficiency in the design.
