Advantages of the board:Boot no current impact sound, high fidelity no static noise! Sound quality super good – treble delicate, soft, transparent, no obvious harsh; bass strong, full, powerful, retractable. Recently, a small number of customers reflect the board a bit noise, mostly power problems are not resolved. After testing, with more than 12V2A battery or 12V30W transformer power supply no noise, if the use of switching power supply or other variable power supply, due to poor sound may produce low noise.
