Precisely Crafted Amplifier with Vintage Vacuum Tubes

A carefully engineered circuit with (x5) 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.

• Matched pair of Amperex 17BF11 NOS dual pentode composite tubes for SE Class A power amplification
• Matched pair of Amperex ECF82/6U8 NOS high-gain pentode / medium-gain triode composite tubes for voltage amplification
• Single RCA 17AX4GT NOS rectifier tube for pre-amp stage plate power supply

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.

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 Startup Delay Circuit: Protects your tubes and minimizes noise related to the warm up cycle of the amplifier

Reference Grade Point-to-Point Wiring: Cayin vacuum tubes are point-to-point wired to ensure the shortest signal path. The entire circuitry is hand-wired by skilled, attentive to detail craftsmen using premium components.

Exquisite, Refined Aesthetics: seamlessly integrates with the Cayin portfolio and features dual retro VU meters, Vacuum Tube protection cage, and premium chassis finish with uniform color and fine contours.

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.
