My 2Stepdance is dead silent until around 2 o'clock on the the volume with the iems I have tried which varies from Etymotic HF2 (low impedance), Etymotic ER4PT with 75ohm adapter (100 ohm) to Heir Tzar 350 (350 ohm). That said I never get that high on the volume so it's a non issue for me. 
 
Concerning radio interference I can confirm it's prone to that but so is a a number of other portable amps I would guess - also had the problem on the iQube when I had that. I find it's only a problem for me when I am close to people/my own phone run on the Edge network, 3G gives no interference. It's still very annoying when commuting by train.

 Was your 2stepdance set to low or high gain when you notice the hiss at 2 o'clock?
 
The radio interference can be so ignoring that I can not longer bare using it as a portable with iem..sigh 

sorry meant annoying, not ignoring lol

set to high
