- Class A Headphone Amp & Pre-Amp
A Class A amplifier conducts signal over the entire range of the input signal cycle. The output transistors are biased to operate in their most linear range, and there is no crossover distortion caused by switching the signal between two push-pull devices. The HA-1's power amplification circuit for the headphones is Class A built with discrete transistors. The amp includes fully balanced analog inputs and outputs, purely analog volume control, and an adjustable headphone gain switch.
ESS ES9018 Sabre 32 Reference DAC
The SABRE 32 Reference ES9018 from ESS Technology is the world’s best performing 32-bit audio DAC solution made for high-end consumer applications and professional studio equipment. With the ESS patented 32-bit Hyperstream™ DAC architecture and Time Domain Jitter Eliminator, the SABRE 32 Reference DAC delivers an unprecedented DNR (Dynamic Range) of up to 135dB and THD+N (Total Harmonic Distortion plus Noise) of -120dB, the industry’s highest performance level that will satisfy even the most demanding audio enthusiast.
Toroidal Power Supply
A toroidal power transformer offers superior power efficiency and much lower exterior magnetic fields over traditional laminated steel core transformers. The HA-1's toroidal linear power supply provides a very clean and robust power source to the audio components.
High Definition Audio Support
The Oppo HA-1 has numerous digital inputs including coaxial, optical, AES/EBU, and an asynchronous USB DAC input that supports PCM up to 384 kHz 24-bit and DSD up to 12 MHz (DSD256).

Made For iPod, iPhone and iPad
The HA-1 passes Apple's "MFi" certification and is compatibile with the latest iPod, iPhone and iPad so that it can be used as the digital audio output accessory of these devices. By tapping directly into the digital audio signal of these devices and converting the audio to analog using the high performance SABRE 32 Reference DAC, music from your favorite portable device will sound brilliant.
The HA-1 is placed in a brushed aluminum chassis. The Class A amplifier naturally consumes more power and emits more heat than other types of amplifiers, so the HA-1 is designed with emough ventilation and built with the finest materials to ensure long term stability and performance. At about 6kg, the HA-1 is a solidly built desktop headphone amplifier.

" Oppo's HA-1 is a very flexible headphone amp and home theatre DAC/pre-amp and about spot-on for the money."
" The Oppo HA-1 headphone amplifier is definitely a slam-dunk for audiophiles."
" Worth auditioning at this price, but it needs to deliver more energy and excitement for the full five"
" I think the HA-1 is good enough to use as a reference, and in fact, because of its preternatural neutrality, it makes a good reference indeed. But more than that, I just plain enjoyed listening to music on the thing. And I enjoyed it frequently. I also enjoyed looking at it."
" Nothing on the market has a price to features and performance ratio like this. The HA-1 is in a class all by itself. Housing the 2nd best audio clarity in the price tier, Oppo has achieved something few others have and I seriously doubt anyone is going to offer another DAC/amp in this price tier that offers this level of clarity as well as 1up Oppo with even more features. Oppo shot for the moon and ended up on Mars, but the amp isn’t without faults, although it still outscored nearly every other sub $1500 DAC and amp I’ve ever used."
" If you have a good pair of headphones, you owe it to them (and yourself) to pair them with a good amp and DAC. And the Oppo HA-1 is a very, very good amp (and DAC). Highly recommended."
