High performance Headphones amplifier [ HPA-20 ]
Direct sales price : 200,000 yen






When it was compared with the power amplifier, there were many headphones amplifiers which it had the circuit which was a simple target it makes do with for so far.
We had the thought of "The power amplifier and basic structure don't change into the headphones amplifier as well." developed by the circuitry with no compromise in the place.
It is the high-performance headphones amplifier of this rank side.
Dynamic-headphones were compared with capacitor-headphones, and it was said so far that a resolution Noh play was inferior.
But, "HPA-20's" are the high resolution Noh play which is equal to the capacitor type, and the headphones amplifier which makes the powerfulness of the dynamic go together.

Attention: A high-performance DA converter is necessary to show the performance of HPA-20 fully.
