A Gorgeous Amp That Sounds as Good as It Looks

A five-time winner of The Absolute Sound  Editors’ Choice Award, the hefty Cayin HA-1A amplifier is meant to drive the highest-grade headphones to their best potential. Its eye-catching design leaves a lasting impression, with a window on the front plate that provides a view of the 12AX7, 12AU7, and EL84 tubes inside. So the amp can be perfectly matched to your headphones, it features an impedance selector switch that ranges from 6 to 300 ohms. Plus, it can be used as an integrated amp for passive speakers and features an output of 1.2W x 2 (RMS, triode) or 2.2W x 2 (RMS, ultralinear). 

Note: This drop is for the original Cayin HA-1A amp (not the MKII version) in black or silver. Quantities are limited to eight units of silver and four units of black. Because it’s only available in 230V, members in the US will need to use a voltage adapter.

The Reviews Are In

Head-Fi user Ferbose says, "It can sound as good as other headphone amps I have heard below $1,000 USD, delivering an open, smooth sound with the tonal purity one would expect from SET topology. It can drive any low-sensitivity headphone with ease, but using it with high-sensitivity headphones would require some attention to choosing low-noise tubes. In addition, it can perform satisfactorily as a preamp or a flea-power SET speaker amp, which makes it a really great bargain."
