The HPA V100 was developped with the target to enable highest transmission quality for low- , medium- and high-impedance headphones.
Due to its specific, variable, low-noise and low-distortion circuit design especially optimised for dynamic headphones, the HPA V100 fulfils even highest demands.


because of low internal gain.
Therefore the self generated noise from the amplifer is not audible.

through 60 Volt internal operating voltage.
Therefore best suited for high impedance headphones.
Over 90 % of all headphone amplifiers in the market offer not half that voltage !! 

because of powerful amplifiers able to deliver much more current a headphone needs.
Therefore best suited for low impedance headphones and even magnetostatic cans !!

through lowest output impedance.
Therefore best suited for full control even over critical headphones with the garantee to have flatest possible response.
