Featuring three individually selectable impedance ranges – Low from 8 to 64 ohms, Mid from 65 to 250 ohms, and High up to 600 ohms –, the HA-300MK2 is said to be suitable for a wide variety of headphones with different impedances. Amplification on the output side is done by a pair of 300B Direct Heated triodes and two 6SN7 driver tubes. With that, the amplifier is supposed to be able to reliably output the signals both balanced, via XLR and 4.4mm connector, and unbalanced. The 4.4mm output is also said to be both lower in output power and noise.
The HA-300MK2 is powered by its own separate power supply, which sits in a matching housing. In addition to a toroidal transformer, it contains four NOS RCA 22DE4 rectifier tubes, which are supposed to drive the amplifier cleanly and without interference. The PSU is connected to the power supply via a silver-plated Teflon cable with copper connectors.
The HA-300MK2 is also said to be able to drive speakers, and carries speaker terminals on the back that can be activated by a switch and are supposed to drive speakers with 2 x 8 watts for this purpose. In addition to these, the RCA and XLR inputs are also located on the back of the device, and the front is rounded off by two VU meters. Other features such as silver-plated inner wiring, short signal paths, a 41-step ALPS potentiometer, silicone gel dampers and a start-up delay are also said to further enhance the HA-300MK2's performance.
The black version of Cayin's HA-300MK2 is said to be available now*, with a silver variant to follow in August*. The headphone amplifier is expected to cost around €5500*.
