Welcome to Cayin - Headphone amplifier CAYIN HA-1A

Cayin - CD100i CD-Player

Universal: the Cayin HA-1A can be used as a headphone amp as well as an preamp or even an integrated amplifier. The 2 x 2.2 watt in ultralinear mode should be sufficient for high efficiency loudspeakers. The EL-84 tubes can be switched into Triode mode. A switchable impedance from 6 to 300 W allows a perfect matching with your headphones for maximum sound quality.

"The HA-1A may be the best thing that's ever happened to headphones...champagne sound for beer-budget bucks." Sam Tellig, Stereophile, June 2006
