About the HA-6A
The Cayin Audio HA-6A is a high-power, transformer-coupled Class A tube headphone amplifier with selectable Triode (TR) and Ultra-Linear (UL) operating modes, impedance-matched headphone outputs, and both single-ended and balanced connections. It supports EL34 or KT88 power tubes and includes selectable low, medium, and high headphone-impedance ranges. The HA-6A is distinct from the newer, separately designated HA-6A MK2. Available product listings and Cayin-related documentation identify the original HA-6A as an established model, while the MK2 has appeared as its successor; however, the available sources do not provide a definitive manufacturer statement that the original HA-6A has been officially discontinued.
