The Cayin HA-3A Tube Headphone Amplifier allows you to enjoy your favorite music on your headphones with the best sound quality. It combines top-notch engineering with the exquisite vintage design of a classic tube amp.
The amp offers various switching options – for connecting the source, balanced on XLR connectors and unbalanced on RCA inputs are provided. Moreover, if necessary, you can connect two sources to the Cayin HA-3A and switch between them with a toggle switch on the front panel.
For headphones, on the front panel of the device there are not only a 6.3 mm unbalanced jack, but also balanced outputs on 4.4 mm minijack connectors and a 4-pin XLR. Pointer indicators of the signal level give the component a special charm.
The input stages of the Cayin HA-3A amplifier are made on two ECC82 double triodes, and a pair of 6V6S tubes work at the output. The power supply uses a 22DE4 diode. The amplifier is capable of driving headphones with a nominal impedance of up to 600 ohms. To select the load resistance, a special three-position switch is provided on the front panel of the device.
Sales of the Cayin HA-3A tube headphone amplifier have already begun. Now the amp is offered only in black, but the manufacturer plans to add a silver version over time.
