The HA-6A Mk2 is a headphone amplifier from Cayin, built with detailed per-connector, per-mode power specifications and a separate power-supply chassis. The HA-6A Mk2 brings Cayin's considered engineering to dedicated headphone amplification.
Key specs that matter
Maximum power via 4.4mm Pentaconn is 2 x 1,000mW in Ultralinear mode or 2 x 650mW in Triode mode; via 6.35mm it rises to 2 x 3,500mW Ultralinear or 2 x 2,300mW Triode - a distinctive selectable configuration allowing a choice between greater power and triode's characteristically warmer signature. Frequency response spans 10Hz to 26,000Hz within plus-or-minus 3dB. Total harmonic distortion is 0.3% at 1V RMS into 300 ohms. Signal-to-noise ratio is 104dB. The amplifier chassis measures 285 x 185 x 297mm at 11.2kg, with a separate power-supply chassis measuring 160 x 195 x 297mm at 8.2kg.
Sound and use context
Expect the warm, richly textured character tube-informed headphone amplification is broadly celebrated for, with the distinctive Ultralinear/Triode selectability offering the listener a choice between greater power and a more characterful triode signature.
Pairing
The distinctive selectable operating modes let the listener choose the sonic character to match different headphones or moods.
Alternatives
Cayin's own HA-300 MK3 offers a related flagship-tier alternative within the same broader headphone amplifier catalogue.
