sHP-100 is a combined USB DAC & high performance headphone amplifier.


The unit supports USB, Coaxial, Optical and Analog line input and has headphone output as well as analog line output.


As for DAC function of the unit, there is Line output select switch on the bottom side of the unit, you can set the analog line output to the variable line output or the fixed line output. If you set to the variable line output, you can connect the unit to Power-amplifier and control the analog line level by Volume control knob on the front side of the unit. If you set to the fixed line output, you can connect the unit to Pre-amplifier or Inti-amplifier.


As for headphone output, you can control the output by Volume control knob on the front side of the unit, and set the output impedance of headphone by Headphone impedance select switch on the bottom side of the unit.


Also, the unit has 3.5mm stereo line input jack on the front panel so you can use the unit as a headphone amplifier or pre-amplifier by connecting the unit to your smart devices or portable audio player.


The unit use AK4113 DIR chipset of AKM for Coaxial and Optical digital input and supports 24bit/192KHz playback. For USB input, it supports 24bit/192KHz PCM and DSDx64, x128 playback through multi core RISC processor by XMOS and also USB audio class 2.0.


All digital input sources translate via CS4398, Flagship DAC of Cirrus Logic to analog signal and output via LME49720 & TPA6120A2 of TI which are one of the best audio OP-AMPs & headphone amps. Also the unit minimizes the distortion of audio signal by the volume control circuit using exclusive audio variable resistor of ALPS.


For the high quality power supply, ULNR(Ultra Low Noise Regulator) is used for digital&analog circuit. Extremely Low Jitter Oscillator and Active Noise Canceller is used for clock circuit which is the most important part of the DAC module, these technics prove making the best sound among any same level devices.


The unit doesn’t need the extra power supply since it can run via USB power only, but with mBS-d2s(battery power supply), they will perform better, make a much beautiful sound and be a great matching system visually.
