The HA500H is a premium Hybrid Headphone Amplifier, DAC, Pre-Amplifier and Asynchronous USB DAC for audiophiles. It is equipped with two(2) ECC82 vacuum tubes and solid state OP Amp, which will work as preamp stage for the headphone section, and will work as out stage for the pre-out section, while solid state transistors are built in at power amp stage for headphone section. So, you can select one out of Tube and OP Amp according to character of music, your feelings and mood.
All music has its own character. Some music need to be reproduced clearly and dynamically, others will be better when they are played warmly and smoothly. The HA500H will be the best device that will let you choose different sonic signature in reproducing music according to your feelings and music character.
The HA500H offers impedance selector(High/Low) with which you can choose one of High or Low impedance, which suits better your headphones.
Equipped with two(2) Sabre³² ES9018K2M DAC(one DAC per channel), additional multicore microcontroller for high performance USB Audio DAC, completely isolated circuit design for analogue and digital section with customized SMPS and Toroidal Transformer and high quality aluminum enclosure crafted precisely by CNC machine with beautiful glass-sanding finish, the HA500H will be Reference Level Hybrid Headphone Amplifier, DAC, Pre-Amplifier and Asynchronous USB DAC for audiophiles
Dual ESS Sabre³² ES9018K2M DACs built in for right channel and left channel separately
Two(2) Sabre³² ES9018K2M DAC chips are built in for right and left channels separately. The world's best performing 32Bit audio DAC solution, the ES9018K2M offers unexampled DNR(Dynamic Range) of up to 127dB and THD+N(Total Harmonic Distortion plus Noise) of -120dB. As the HA500H is circuit-designed with two DAC chips allocated for each channel separately, its Dynamic Range will be far increased and much better sound quality can be guaranteed
Two(2) ECC82 Vacuum Tubes
Based on our exclusive technologies to match up solid state electronics with vacuum tube, the HA500H was developed to let audiophiles and music lovers experience mellow and enthralling sound adding warmth and depth to the music. A pair of ECC82 Vacuum Tubes are installed for preamp stage of headphone section and for out stage of pre-out section. It delivers a breathtaking sound enough to attract audiophiles' attention
Balanced Circuit Design
The HA500H is circuit-designed by fully balanced technologies for internal analogue audio signal path. The unbalanced(single-ended) analog input will be converted to the balanced at input buffer, and it will go into ADC. The balanced analog input will go into ADC as it is. For all digital audio input, the signal flows in balanced mode all the way from the DAC to the output connectors. All single-ended(unbalanced) outputs are originated from the balanced signal as well. The balanced circuit design surely helps to reduce common-mode noise and improves signal quality. The balanced headphone output provides twice the voltage and four times the power of the single-ended(unbalanced) output, enabling the HA500H to drive headphones which request lots of power. It also provides better channel separation by eliminating the common ground return path.
Isolated Power Source Circuit Design and Toroidal Power Transformer
To minimize idle noises and electrical interference, power source for digital and analogue section is isolatedly designed. Instead of cost-effective laminated steel core transformers, the HA500H applied the customized high quality toroidal power transformer which ensures unexcelled power efficiency and minimizes exterior magnetic fields.
Perfect Asynchronous USB DAC and Hi-Res Audio
For audiophiles and music lovers who use PC, X50D or X50Pro as source device, the HA500H will be a perfect Hybrid Asynchronous USB DAC, which will surely deliver a wonderful sound by using the high precision clock inside to drive the audio signal precisely and dual ESS Sabre³² Reference DAC chips inside to convert digital signal to analogue. The HA500H USB DAC Input supports MQA(Master Quality Authenticated), Native DSD64/128/256 and PCM signal up to 32Bit/384Khz
Wireless Playback via aptX Bluetooth
As HA500H offers Bluetooth receiver which allows you to play music files in your mobile devices wirelessly via the HA500H. It supports A2DP and AVRCP profiles and SBC(Subband codec), aptX, AAC and MP3
12V Trigger Input and Output
Ideally, it is best way to power on in order of a source device, DAC, Pre-amplifier and Power Amplifier when power on hifi audio systems, Of course, the reverse order is recommended when turn off the power. The HA500H offers 12V trigger output and input. When it is used as a pre-amplifier, its trigger output can power on the connected power amplifier automatically when the HA500H is powered on. If you connect its trigger input to the trigger output of the connected source device, the HA500H can be turned on automatically when the source device is powered on.
Selectable Headphone Out Impedance / Highly Adjustable Gain Setting
The HA500H offers the feature to select Headphone Output Impedance(High/Low), so that you could set to proper impedance for optimal sound quality and the best matching with your headphones' sensitivity. You may select one of High and Low.
The HA500H's volume can be precisely and seamlessly controllable via the bundled cute remote control. The headphone amplifier also provides separate adjustments for the impedance and sensitivity of the connected headphones, as well as different levels of the audio sources. This features allow headphones between 16 ohms and 600 ohms to be worked perfectly with the HA500H with wonderful sound quality.
The HA500H offers very high connectivity. As it provides Analog Inputs(Balanced and Unbalanced), Digital Inputs(Coaxial, Toslink, AES/EBU), I²S Input(HDMI) and USB Audio Input, you can connect various source devices to the HA500H almost without limitation. Especially, the HA500H can be connected to the I²S HDMI Output of the X50Pro and X50D perfectly to play Native DSD, MQA and up to 384Khz PCM with great sound quality.
