Looking at our new HPA-01, you won't need a magnifier to notice the spitting image of the multiple award-winning HPA-21.
We daringly disassembled the HPA-21, condensed and simplified details, carefully redesigned and reduced it to a more budget-friendly version. But don't get us wrong. The transcendental soul of HPA-21 remains untouched in the HPA-01. Sharing the same core technology, namely our SATRI Circuit and unique current driving method, the HPA-01 delivers unmatched precision and power to the most demanding headphones.
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.
