Cayin HA-2A Tube Headphone Amplifier

The new HA-2A from Cayin sets new standards in audio performance as a balanced tube headphone amplifier featuring selected NOS tubes. This masterpiece combines the unique warmth and smoothness of vintage NOS vacuum tubes with state-of-the-art technology to deliver a breathtakingly detailed sound with a wide soundstage and excellent musicality. Equipped with a pair of selected Amperex 17BF11 NOS double pentodes and a matched pair of Amperex ECF82/6U8 NOS for power and voltage amplification, as well as an RCA 17AX4GT NOS rectifier tube, the amplifier promises an incomparable listening experience.

Thanks to the innovative single-ended Class A amplifier circuit developed by Cayin's engineers, the characteristics of the tubes used are optimally utilized. Multi-stage filtering, low-noise FET voltage regulation, and the specially developed EI output transformer with a Z11 core guarantee perfect control of headphone loads and produce a balanced, warm sound with rich harmonic characteristics.

The HA-2A offers three settings (High/Mid/Low) to optimally match the headphone outputs to the impedance of the connected headphones, achieving a high output power of up to 1000 mW per channel. The transformers play a decisive role in the amplifier's performance, with the high-quality, wide-bandwidth EI transformers being specially developed for the HA-2A. These deliver ample power with high efficiency and extremely low distortion.

Versatile connectivity options, including three headphone outputs (two balanced and one single-ended) as well as two analog inputs (XLR and RCA), offer flexibility for a wide variety of audio devices. All Cayin tube amplifiers are hand-built using point-to-point wiring, which guarantees the shortest signal path and improved detail.

The HA-2A fits seamlessly into the Cayin i-8 series, allowing for visual integration with the iDAP-8 digital streamer and the iDAC-8 DAC to form a compact desktop system. Despite its compact dimensions and a weight of just 10 kg, the HA-2A offers exceptional audio performance and harmonic aesthetics. With an extensive metal finish and a resin seal, the amplifier remains in top condition even after intensive use. A power-on delay circuit minimizes clicking sounds during activation and ensures that the tubes are optimally warmed up before music playback begins.

The HA-2A is an unbeatable combination of price, performance, and craftsmanship for a highly rewarding, musical listening experience.
