Discrete Class A Balanced Headphone Amplifier

Asynchronous USB DAC Up to 384 kHz and DSD256

Stereo Pre-Amplifier with Home Theater Bypass

Compatible with iPod/iPhone/iPad and Bluetooth

Uncompromising Audio
built with the latest technology

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 hefty toroidal power transformer, and 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 fully balanced Class A power amplification section uses hand-picked and paired discrete components to ensure symmetry, and a motor-driven precision volume control knob allows for both manual and remote control volume adjustment while keeping the audio in a pure analog audio path.

Class A Headphone Amp and Pre-Amp
Fully balanced analog inputs and outputs, purely analog volume control, and an adjustable headphone gain switch.

Toroidal Power Supply
A custom OPPO transformer provides clean power with plenty of energy reserves.

Mobile Device Support
Bluetooth with Apt-X codec for high quality wireless audio and a USB input for mobile phones and tablets.

ESS 9018 Sabre³² Reference DAC
High resolution performance with extremely low noise and distortion.

High Definition Audio Support
Numerous digital inputs including coaxial, optical, AES/EBU, and an asynchronous USB DAC input that supports PCM, DSD64 and DSD128.

Display Driven Interface
Physical volume and source selection knobs frame a 4.3-inch display for easy operation.
