Could anyone who has owned/heard both iems please point me in the right direction? Maybe listen to the track below on your NM2+? This track has super phat ear-massaging bass, so I'd love to know how it comes through on the NM2+
This may not directly answer your question, but...
In some cases, I'd recommend the TRN BA5 for Psy-Trance. It's actually my top performer for that genre. As long as it's not too bass-heavy. It's more of a treble performer.
That said, I tested your track with the BA5. It actually kind of does have 'ear-massaging' bass. But it's not as clear-sounding as what I'm used to with that IEM. Soundstage with this 'E.V.P.' is pretty good, the positioning of instruments is, well it's amusing.
The bass is sounding kind of muddy. It's not thumping or slamming with the BA5, and the texture is a bit barren. So the BA5 is not terrible with this, but it's not the star either.
I then tried it with the V90. Surprisingly, the bass was not more 'ear-massaging' near the same volume, and only somewhat more thumpy. There was a greater overall bass presence. The BA5 was kind of 'flat' with this track, the V90 kind of incoherent. I am surprised. Maybe I should try the TFZ No. 3, that's supposed to be a bass performer.
V90 did get to 'ear-massaging' when I turned up the volume [and I have a higher-impedance cable on it], but I don't like to listen at that level. Still a kind of coarse sound.
BA5 is good for synthy stuff sometimes - BA5 owners, check the first one out:

and basic trance:

and bass-moderate DnB:

BA5 vs V90
Interestingly, I think the V90 handles the following tracks better than BA5:
If we want to talk psy-trance, the V90 grinds, snaps and thumps nicely on this track:
BA5 is more clear with this track, and makes more phat sounds, but the bass is not as thick or diverse. Synth noisemakers are more prominent, vocals more clear, and bass beat is tight, but I think it isn't digging as deep in the bass. Bass information not as diverse.
So I don't know if this provided any data for your question, but it seems to me that DnB and especially psytrance can teach us about BA5 vs V90! Seriously though, the NM2+ is probably good.
I learned that BA5 and V90 could be good for DnB and Psy-trance, but not consistently good [other tracks were not always up to par.]
