YULONG HEF188 hi-end Headphone Amplifier

Experienced engineers on HEF188 R & D : “After the Audio test of the first edit of AD1865,I am fall in love with the classic nobler DAC. It is very difficult that the chip bring into full play perfectly. From year 2004 to now, we have developed and tested for a long time. We changed the circuit and the layout of PCB. We have made 8 models, after tested and amended for heaps of times. And now we are satisfied with and confidence for its performance and voice, so we show it with you who are funs of stereo system.”
