The MSB Technology Premium Quad USB2 Module is a new USB input module for the Analog DAC that represents a substantial improvement in the application of USB technology for this highly respected DAC. Both Michael Lavorgna and I have previously reviewed the Analog DAC (see Steve's review
and Michael's follow-up
) and found it to be an excellent sounding DAC that was characterized by a relaxed natural sound. At the time of my review of the Analog DAC in 2013, MSB sent me the Platinum Data CD IV Transport to be used in the evaluation of the Analog DAC. MSB Technology felt that this transport connected to the MSB Network input module had superior sound to the USB Basic 384 input module and would better demonstrate the capabilities of the Analog DAC. Although I could get somewhat close to the sound of the Platinum Data CD IV Transport with numerous hardware tweaks and software programs, I still found the Transport to be better sounding than using the USB Basic 384 module.
