To get the best sound quality of your headphones, an external headphone amplifier is needed. In collaboration with degreed engineer Frank Blöhbaum we developed the KHV-200. It was designed that almost every headphone could be driven with the best sound quality. Beside a 6.3mm headphone socket it also has an 4 pin XLR socket for the connection of high end headphones.
