@twiceboss what you might be hearing is the emphasis of the mids and midbass over sub bass. There's no tick up in the midbass to balance the treble, so you're ending up with what sounds like cluttered mids or emphasized midbass, but what is actually de-emphasized sub bass.
EQ can work in two directions, either by adding the desired frequency or the removal of those around it.
There are two other possibilities to consider. First, I've heard the Estats require more power than standard BAs. I don't have any underpowered sources here to test. It could simply be a matter of feeding your IEMs more power.
The second consideration is that the stock Fearless cable is terrible, and I know I seem to harp on this a lot, but it is really REALLY terrible. Replacing my S8P cable with a higher quality cable lifted the veil and increased performance noticeably. The replacement just immediately started cutting out. The Roland cable was faulty right out of the box, and, just like the S8P, a replacement made everything better.
