Sonodore Headphone Amplifier HPA-1000

This headphone amplifier is developed to expose and complement the unmatched
sonic characteristics of the 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.

Although the amplifier is optimized for the AKG K1000, it is also very useful for other
