Very High Sound Quality,
Absolutely mint(like new) no scratches.no marks,not even a fingerprint (minimal use)
comes with manual,remote,accessories  / power cord,in box (original packaging).
When this is unpacked by a prospective buyer they will think this is a new
unit ,it is that good.
Power Supply : Auto sensing 110~120v to 220~240v
Can be used in USA or Canada/or any country with these voltages.This is in the specifications and confirmed to me by OPPO in a email
Inputs:
USB DAC,Bluetooth,Mobile,Optical,RCA,Balanced,coaxial,AESVariable and fixed output’s. Graphical Volume control
Large color display (dim completely if required ),a versatile component with Superior sound quality.
Balanced XLR and RCA output at the same time(very handy to connect to a sub wooferand a amp at the same time

Can Ship anywhere/you will not find a more perfect HA-1 in the World

HIGH PERFORMANCE AUDIODiscrete Class A Amplifier
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 discrete design allows us to hand-pick and match the best parts to build the HA-1.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.Fully Balanced Design
The internal analog audio signal path of the HA-1 is fully balanced. For digital audio, the signal runs in balanced mode all the way from the DAC to the output jacks. Balanced analog input is kept intact, and single-ended input is converted to balanced at the input buffer. All single-ended outputs are derived from the balanced signal as well. The balanced design provides better common-mode noise rejection and improves signal quality. The balanced headphone output provides twice the voltage and four times the power of the single-ended output, enabling the HA-1 to drive the most power hungry headphones. It also provides better channel seperation by eliminating the common ground return path.ESS Sabre32 Reference DAC
The DAC is one of the most important components for digital audio playback. The SABRE32 Reference ES9018 from ESS Technology is the worlds best performing 32-bit audio DAC solution targeted for high-end consumer applications and professional studio equipment. With the ESS patented 32-bit Hyperstream DAC architecture and Time Domain Jitter Eliminator, the SABRE32 Reference DAC delivers an unprecedented DNR (Dynamic Range) of up to 135dB and THD+N (Total Harmonic Distortion plus Noise) of -120dB, the industrys highest performance level that will satisfy even the most demanding audio enthusiast. To learn more about the technologies behind the exceptional performance of the SABRE DAC, please read the SABRE Technical White Paper.
