HPA-3U Class A Full Balance Headphone Amplifier

HPA-3U is a new member of the M-Stage series headphone amplifier, who is the first one full-balanced design

of the headphone amplifier, both supports single-ended output and differential output, maximizing the

performance of the headphones.

Full-band of THD + N less than 0.0003%, SNR up to -112dB, bandwidth not less than 150k at -3dB gain,

0.4Omega, three gain level options to fit for the different impedance and sensitivity headphone, all of these

excellence performance improvements to be born the brand new HPA-3U!

Excellent structural design to quickly dissipate the heat of power transistors via the shell, full symmetric circuit layout, fully differential signal path amplification, driver stage is the precision constant current source, the precision quadruple potentiometer volume control, so that the HPA-3U has better dynamic range and details than a single-ended headphone amplifier.

The Alps customizes model of volume potentiometer, Wima and Nichicon audio grade capacitors, Noratel toroidal transformer, precision non-inductive resistance, each carefully selected components make HPA-3U not only presents the perfect sound, but also a more stable and reliable.
