I love getting broke on music improvements! Please tell us more. How would you describe the differences to the M8?
Does th M30 deliver the same level of musicality / engaging sound as the M8? (higher number is often but not always "better")
Where would you say it excels?
I really like the general concept of the M30. Since I have two M8 of which one replaced my former "big" digital solution, M30 might be an even better replacement.
Mobility is not an issue here. But it needs to be at least on the musical level of the M8.
I have just been listening to the M8 and the M30 over the weekend. Let me consider it from the perspective of an IEM. I am using the FitEar DC which is pretty tough to drive. I think the M30 has a more spacious sense to the sound signature while retaining the musical and emotional slant of the tuning on the M8.
