You do not want to be using an amp with high output impedance with a sensitive IEM or headphone. Especially one with cross overs. It will screw up the sound. Always opt for a portable amp with less than 1 ohm and a low noise floor. As I had said the UHA4 or UHA6 MKII will do this for you.

BTW, where do you see the spec sheet which tells about the "90Hz/ 180Hz" hum?

Its not in the spec sheet, E7 was tested on a test bench which reviews a slight hum caused by E7's power supply. Actually low impedance design is much more commonly seen in studios these days since a lot of equipment have the output to support for low ohm phones.
