Precisely Crafted Amplifier with Vintage Vacuum Tubes

A carefully engineered circuit with five vintage NOS vacuum tubes

The amplifier has a stunning sound, rich in detail, with a wide soundstage and
excellent musicality. It also offers the unique mellowness
and warmth of vintage NOS vacuum tubes.

Specialized Single-ended Class A Tuning

Our engineers have designed an amplification circuit in single-ended Class A to
take full advantage of the characteristics of each NOS vacuum tubes

Through ingenious design and carefully planned wiring, we have preserved
the balanced, mellow, warm sound and rich harmonic characteristics
during the tuning processes.

Multi-stage filtering and low-noise FET voltage regulating circuit,
along with in-house developed Z11 core EI output transformer, achieve perfect
driving for headphone loads.

Critical Core-Competence in Making Tube Amplifier
In-house Developed Wide-bandwidth Transformers

Transformer plays a vital role in transformer coupled vacuum tube amplifier.
The design and implementation of transformers become an important part
of our product tuning.

The output transformer and power transformer use high-quality wide-bandwidth
EI transformers specially developed for HA-2A. They use Z11 EI type iron core
from Japan, and are wounded using Cayin's precise hand-winding process.

With a fully enclosed metal casing and resin sealing, these transformers deliver ample
power with high efficiency and extremely low distortion because the magnetic field
interference has been reduced to a satisfactory level

Fully Optimized Headphone Outputs

2 x Analog Inputs: XLR and RCA

Can be used with CD players, DAC, portable players, and
any audio devices with line level output

Reference Grade Craftsmanship
Point-to-Point Wiring

All Cayin vacuum tube amplifiers are point-to-point wired to ensure
shortest signal path and better attention to detail, the entire circuitry is
hand wired by skillful craftsmen.

The internal circuits of the HA-2A, from tube connections to resistors and
capacitors, are soldered and carefully routed using premium internal
wirings to enhance signal transmission speed and low interference
throughout the entire circuit.
