Well after letting the iem card burn in for approximately 24 hours and conducting a track by track comparison with my SE5 here are my findings:
- The iem card has as much punch / good dynamics as the balanced card with the SE5. So I doubt it will lack power for any iem.
- It adds A LITTLE BIT of space / air vs. the balanced card
- I was wondering why something soudned a bit off / fatiguing with the iem card, and I found out...the mids have a tendancy to become sibilant with the iem card, in quite a significant way
Overall, I prefer the balanced card with the SE5, mostly because of this sibilance issue. Therefore I will stick to it. I will do the test with my NT6 when they get back from reshell, and maybe with the Roxanne if I ever get them, otherwise the iem card will go on the for sale thread.
