I like my N05xd and was torn between it and MSB Discrete. I have a bad case of "what if". I bought the N05xd based on getting to try it in my system and price, once I added the needed USB unit and extra power supply the MSB package price got up there.
MSB is the least digital sounding digital playback I have personally experienced. I regret not being more persistent in trying to get an in-home audition with the Discrete just to know I made the right choice for me. Usually at the show I hear the. entire MSB set up, it's like being in love with someone you know you can't have. I need to hear how the MSB does with other than show type music. I listen to a variety of music including Rock. I can say the N05xd provides the dynamics and detail of Rock without becoming offensive and that's even with neutral studio type speakers like mine. In the back of my mind I always wonder, what if.
