Overview 1 ● ● ● ● HPA-3B is a new member of the M-Stage series headphone amplifier, which is a full-balanced design  headphone amplifier, supporting both single-ended output and differential output, using the adaptor plug to be used in a single-ended input mode, maximizing the performance of the headphones.

Full-band of THD + N less than 0.0003%, SNR up to -114dB, bandwidth not less than 140k at -3dB gain, 0.4Ω  

Three gain level options to fit for different impedance and sensitivity of headphones

Excellent structural design to quickly dissipate the heat of power tube via the shell, full symmetric circuit layout, fully differential signal path amplification, driver stage is the precision constant current source, the precision quad-unit potentiometer volume control

All the above features provide an extended dynamic range and detail compared with a single-ended headphone amplifier.

Every component was carefully chosen for the HPA-3B to present the perfect sound as well as stability and reliability.

These include customized ALPS volume potentiometer, WIMA and NICHICON audio grade capacitors and NORATEL toroidal transformer with precision non-inductive resistance.
