The HPA-01 is a little brother of our award winning HPA-21. But don't get us wrong, We daringly disassembled the HPA-21, condensed and simplified details, carefully redesigned and reduced it to a budget-friendly version.
Unlike the conventional voltage driving method, the HPA-01’s current driving method achieves far superior driving precision, power and distortion level unmatched by any other available conventional headphone amplifiers.
Like its larger bigger brother, the HPA-01 also includes the latest analogue battery power supply technology capable of driving the HPA-01 at up to eight hours of playing time.
The HPA-01 is deadly quiet for extreme resolution. Ultra-wide bandwidth translates into the absence of subliminal fuzziness. Simply put, the HPA-01 executes the delivery of sound the way an amplifier should.
