Cayin - HA-2A

Cayin ensures reference-grade craftsmanship in the internal design of the HA-2A by utilizing point-to-point wiring techniques in vacuum tube amplifiers. The detailed wiring process is done by experienced professionals who meticulously hand-wire the entire circuit to provide the shortest signal path and meticulous attention to detail. Every aspect of the internal circuits, from tube connections to resistors and capacitors, undergoes soldering and careful routing using premium internal wirings. This approach aims to enhance signal transmission speed and minimize interference throughout the circuit. To elevate your listening pleasure with the Cayin HA-2A, it incorporates a 60-second start-up delay circuit that safeguards the amplification circuit. This circuit reduces the pop noise when switched on and guarantees the vacuum tubes reach optimal warmth before playback, enhancing your overall listening experience.

The Cayin HA-2A tube amplifier showcases Cayin's expertise in crafting tube amplifiers with their in-house developed wide-bandwidth transformers. The transformers, crucial for tube amps, are custom-made with high-quality materials and precise winding techniques. They reduce interference and deliver efficient power with minimal distortion. The output and power transformers are meticulously designed with high-quality Z11 EI-type iron cores from Japan and Cayin's precise hand-winding process. The transformers are housed in fully enclosed metal casings with resin sealing, ensuring ample power delivery, high efficiency and exceptionally low distortion due to reduced magnetic field interference. The Cayin HA-2A also equips a multi-stage filtering system and a low-noise FET voltage regulating circuit, combined with the specially developed Z11 core EI output transformer, to achieve perfect headphone load driving.

The Cayin HA-2A features optimized headphone outputs, allowing you the freedom to listen to music with your preferred headphones. It equips a 4-pin XLR connection, designed for high-output demanding headphones. The 4.4mm connection is provided for easy connectivity with high-sensitivity portable headphones. The Cayin HA-2A offers high output power of up to 1000mW per channel and three impedance-matched headphone output settings: High (251Ω ~ 600Ω), Mid (65Ω ~ 250Ω), and Low (8Ω ~ 6482Ω). These settings result in natural sound reproduction with well-defined bass in your music. Moreover, the HA-2A features two analog inputs (XLR and RCA), making it compatible with CD players, DACs, portable players and other audio devices with line-level output.

The exquisite design of the Cayin HA-2A showcases aesthetics, aligning with Cayin's signature design language witnessed in the Cayin 888 3-piece suit. They form a compact desktop system that delivers exceptional audio performance while maintaining a symmetrical visual appeal. Despite its compact and lightweight construction, its dual VU meters with white backlighting add a retro, dynamic flair that catches the eye. The chassis undergoes a meticulous 14-step metal finishing and painting process to achieve a bright, uniform colour with detailed contours complemented by a high-density molecular protective film to maintain its premium shape over time. Above these, the Cayin HA-2A features a vacuum tube protection cage to safeguard the tubes, reduce interference and prevent accidental contact with the heated tubes during operation. It also features an anti-vibration and anti-interference reinforced chassis base to minimize microphonic ringing impacts, vibrations and external interference on the vacuum tubes.
