China is one of the up and coming of good quality but affordable high fidelity equipment. Case in point is the Xiang Sheng USB DAC-01A. Before we continue, for those who don’t know what is a DAC, its an acronym for Digital-Analog Converter. In this case, it converts the digital signal from the USB port to analog signal and passes to an amplifier. The Xiang Sheng USB DAC-01A is an affordable box, but packs a punch in features. I won’t attempt to go into every feature, but just the cool ones that made me throw down the cash to buy one.
