    The HA-1 is a high performance headphone amplifier, and it doubles as an asynchronous USB DAC, a stereo pre-amplifier, a digital audio dock for mobile devices, and a Bluetooth audio transport. Its fully balanced design and numerous inputs ensure the best in fidelity and versatility.

    The HA-1 sports a classic design with contemporary elements. It is a desktop component housed in an aluminium chassis, and the familiar volume and source selection knobs are aided by a 4.3-inch screen for easy operation. Depending on your preference or even the mood of the music being played, you can choose between a classic VU meter, a modern spectrum display, or a simple informational summary on the screen. A supplied IR remote and a smartphone app via Bluetooth provide complete control and convenience.

    The analog audio section of the HA-1 is a fully balanced design with an emphasis on keeping the audio signal in the analog domain once it leaves the DAC. The HA-1 is anchored by a beefy toroidal power transformer. Linear power regulators and filters with custom made capacitors ensure that the headphone amplifier has a clean power source with plenty of reserve energy. The power amplification section uses hand-picked and paired discrete components to ensure symmetry.

    A motor-driven precision volume control knob enables both hand adjustment and remote control while keeping the audio in a pure analog audio path. Users have a choice of using the 4-pin balanced XLR or the traditional quarter-inch headphone jack. Line level analog inputs and outputs are provided with both RCA and balanced XLR sockets. Built-in monitoring and protection circuitry guards against any mishaps such as short-circuiting, overloading, and DC offset that could lead to degraded performance.

    The HA-1 is especially suitable for high-resolution digital audio.

The same ESS 9018 Sabre32 Reference DAC and output driving stage used in our audiophile Blu-ray players ensures extremely low noise and low distortion performance. It is easy to connect the HA-1 to a computer via USB and enjoy jitter-free music using your favorite playback software. OPPO is also working with a leading smartphone and tablet manufacturer to certify the HA-1 so it can pass the required authentication and take digital audio from those popular mobile devices. For additional convenience, the Bluetooth audio transport with high quality Apt-X CODEC sets music in your mobile phones free with a performance boost.
