I have almost made all the parallel port module DACs, and they are really good for application in the audio field. The warm and retro sound makes you unforgettable for a long time. They are too difficult to obtain. This is a 3-year project. I have been looking for an SP9380-18 that can work properly since three years ago. Because in the 18 bit module, only AD1139 can be compared to it. AD1139 has an unattainable price. And SP9380 is indeed very rare. But recently I found him. And make it. 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
