Precisely Crafted Amplifier with Vintage Vacuum Tubes
A carefully engineered circuit with five vintage NOS vacuum tubes, CA-2A sounds stunning. Expect rich detail, a wide soundstage, and effortless musicality along with the unique mellow timbre and warmth of vintage NOS tubes.

Specialized Single-Ended Class A Tuning
Cayin's engineers created a single-ended Class A design to take full advantage of the characteristics of each vintage tube. In every step of the design, component selection, and final wiring, preserving the character of the tubes was carefully considered.

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.
