I would have to agree with what a lot of people are saying though. The amp adds some bass, increases the sound stage, and helps with separation. I'm using it with the T51 and Um3Xs and I love the sound I'm getting. I have to EQ the mids, and bass down, treble up a bit but I love it.

I think what you are finding is that the Rx (a very neutral amp) is restoring the frequencies which your portable source cannot spit out when hooked up the the JH13Pro. There tends to be a hump in the treble and a mild roll off in the bass with just about any portable and the JH13Pro. Restoring treble with EQ means you prefer the hyped treble when in unamped state.
The Rx is fully neutral and it will even the boards with any iem - if you're not used to that sound signature, though, then you will have to get used to it.
