I don't need to introduce SONY company too much. He is the creator of SPDIF. I am unable to obtain the first generation CX890 from SONY. Because people who own CX890 are unwilling to sell. I can only purchase CX20017 or CX20152. Currently, few people in the world make fully balanced CX20017 or CX20152. You can feel different here. He is a truly balanced structure. At the moment when the sound was playing, I was attracted to him. The sound is very clean and full of musical sense. These chips will take you back to the 1990s.Now share with everyone.You will get his PCB at a very low price. But he is in China.If you are a friend of the European Union. Please provide the IOSS number, which consists of IM and 10 digits. The mailing time is about 10 days. All PCBs consist of four parts: audio input board, format conversion board, DAC decoding board, and power board. You can play app content through a Bluetooth chip (purchased in China, manufactured in Shenzhen), or use CS8412 coaxial to play CD content. COMBO384 can also be used to connect to a computer for playback, and there is also an external input IIS interface for connecting to Philips turntable playback. I will provide Taobao product connections. You can use Taobao's overseas warehouse to purchase. If you need assembly instructions and BOM list, please send an email: 410746700@qq.com，My store address: hikvocal.taobao.com
