I have had the good fortune to listen to the MSB Reference DAC a few days ago, as part of my quest to select the front end for a new system.
It was fed by a proprietary music player hosted on a NUC, and played on YG Sonja loudspeakers through a solid state pre and a stereo power amp, pre-production pieces from a new manufacturer.
I listened to a variety of music I know well of various resolution, at quite a low volume setting.
I have been blown away. It has been a long time since I felt so moved by reproduced music.
The sense of cohesion, transparency, resolution, depth and spaciousness of the soundstage has been unparalleled. I am comfortable to attribute most of it to the Reference, as there has been clear differentiation between different tracks.
The thing is, plain redbook recordings sounded like I have never heard them before, and high resolution well recorded tracks were unbelievable and as I have never heard them.
I am deeply impressed by MSB technology and what they have produced.
best,
