Oppo HA-1 Headphone (Pre)Amplifier/DAC
 
 

The HA-1 combines an uncompromising Class A balanced power amplifier section with the performance of the ESS 9018 Sabre 32  Reference DAC.

OPPO designs the HA-1 headphone amplifier with the same universal approach as our Blu-ray players. 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 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. Its digital inputs include coaxial, optical, balanced AES/EBU, and an asynchronous USB DAC that supports both PCM and DSD formats. The same ESS 9018 Sabre 32  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.
