It is also a bit better than the NM2+ when passages become extremely complicated. It doesn’t sound as compressed.
That's an interesting observation about the NM2+ - because that's my biggest complaint about the original NM2. One thing I had been wondering about was whether the NM2+ displayed similar traits.
I like the NM2 a lot for albums that are solo and/or acoustic. However most of what I listen to is rock music that can be complex/fast/energetic, and the NM2 doesn't fare as well for that type of music, at least to my ears.
