Standard version use (three Nikon electrolytic capacitors + Siemens thin film capacitors +evox thin film capacitors +elna non-polar coupled output capacitors)
Upgrade version use (two elna electrolytic capacitors for analog power supply + Panasonic fc electrolytic capacitors for digital power supply +wima Weimar film capacitors + blue silver mica capacitors +ero green film capacitors + Nijikon green non-polar coupling capacitors)
Features:
1. Using double 9038q2m for left-right channel decoding brings higher separation and low distortion
2. The USB part uses a high-digit digital isolation IC to reduce the noise introduced by the USB power supply and ground wire
3. xmos or amanero module can be used for USB part
4. The digital main power supply uses LT1764A fast transient response, low noise LDO voltage regulator IC, 9038q2m DAC uses low noise IC power supply, analog power supply uses domestic Changtel 7815 7915, can use ON Semiconductor 78m12 79m12 Please find customer service remarks
5. With digital volume control, support volume adjustment, use TFT screen long life without burning screen, use Apple infrared remote control
6. Dual power supply, digital analog separate rectifier filter power supply
7. The analog part of DAC uses optical and acoustic in-line resistors and in-line capacitors
8. The board supports Bluetooth interface iis input
