VU header draws:

DCP-1KMKII circuit is derived from the classic differential push-pull output form, Sound schooling is very important. We spent nearly a year on sound schooling, from the selection of transformers and transistors, to the setting of static currents at all levels, and the matching of capacitance and resistance, all of which are targeted, and finally achieve the desired effect. The overall sound of DCP-1KMKII: The background is dark and quiet, the resolution is high, the details are rich, the charm, the emotion, the three-frequency connection is very smooth, the low frequency is soft, and a certain frequency band is not particularly prominent. The higher the sound source and headphone level, the more it can reflect the potential and due strength of the DCP-1KMKII.
