As a (amateur) musician i love my MSB dac. It's the dac that tells the story of music to me. Many other DA converters I have listened to are reproducing notes in a technical way. If I study my teacher sometimes tells me: you're playing vertical notes instead of musical sentences.
I have learned using a good cable with a low impedance is key as the output impedance from the MSB is rather low. Matching with the "wrong" cable does affect the result. But i assume that matching gear and it's connections isn't an unknown here. Also important is to make sure you have the connections right. A MSB dac is fully balanced and when connected to a single ended design trough it's balanced output...it will perform mediocre.
Warranty and product support from this company is extraordinary... and that also has it's price. If you just bluntly say it's expensive and promote another brand...it gives true credit to MSB for making exeptional gear.
Enjoy the music.
