The MSB Technology Premium Quad USB2 Module for the Analog DAC
“As I listened to the Premium Quad USB2 / Analog DAC, I soon realized that sonically this was no small modification of the previous USB2 Basic 384. What I heard with the new module was a substantial improvement in sound quality relative to the older unit. The sound of the Premium Quad USB2 was more open sounding without the slight darkness heard with the USB2 Basic 384 module. Transient detail was better rendered with a greater sense of extension at the high end. The midrange of the Premium Quad was far more transparent and revealing compared to the older module with slightly more presence. Also enhanced was the background silence that allowed micro dynamic detail to emerge with greater clarity. I found the sound staging capabilities of the Premium Quad to truly excel. Thanks to the greater silence, orchestral details stood out in a superior front-to-back depth stage that simply seemed more natural than what I was hearing with the USB2 Basic 384. I felt that the older module had a more distant sound with a slight veil overlaying the music. While the bass attack of the former module was quite good, the new module seemed to be better defined and controlled. Quite frankly, after extended listening with the Premium Quad, I felt that I had evaluated a different higher quality DAC.”
