Since this amp is advertised as most beneficial for IEMs; what sort of IEMs are we talking about here?

From the look of your IEMs now, I would get a high end Universal or a Custom IEM before I got an amp.

The Hawk will drive any IEMs. I have one and use it on my ER4S.

I use my Livewires and my Koss KSC75's with a 75 OHM resistor with this amp. Have not found a reason to upgrade and have has this since they first came out.
