” Does the Quad USB input improve the sound quality? It sure does! MSB really hit the spot with this upgrade. I never expected this level of improvement with this input. It was like I bought a considerably better DAC. Analog Dac remains the best DAC I’ve ever tested/reviewed until now. It’s always a pleasure and a whole journey when listening to music with it.
