I thought they did a lot better than many other IEMs I've tried. What IEMs do you reckon given you an impression of soundstage, out of interest (if any)?
Found a nice combination just now: Audioquest Dragonfly powered via an Aurorasound USB BusPower Pro to the 200s. The effect rather reminds me of a rock/pop concert sound system (though it has been a while, so I could be talking out of my rear a bit here).
TF10's, Senn IE7's...even the X10 present a better soundstage than the 200's to me. To aggravate things, the 200's have a harsh overtone to some female voices I do not hear with the other IEMs so it's like a grating sound coming from right in the middle of your head! Fatiguing. Going back to my T1's puts the vocals back in front of you where they belong with no harshness.
