Sonodore Headphone Amplifier HPA-1000 for high impedance headphones

This headphone amplifier is developed to expose and complement the unmatched
sonic characteristics of the Audeze LCD-4 and/or AKG K-1000 headphone.
Tonal balance, optimal transient response and ultimate transparency are the key
parameters for the HPA-1000. This result in a truly stunning sound.

The amplifier is optimized for high impedance headphones:
impedance higher than 100Ohm.
