That is the whole point of my post we all get so obsessed with it being natural that we do not try to EQ to make it better.
Sound stage is a function of freq. Take the lcd3 or x. It does not have the sound stage that the he 6 has this is caused by the roll off of the upper freq . This is where we get staging cues. Try it and see. And using EQ is so much simpler then actual modding. And it can be played with till it is just right for your ears. Not everyone else's. .
Smartest post I have ever read in a long time. But remember...headphone "soundstage"...to try and emulate a speaker soundstage (which it is not supposed to) inevitably dilutes the purity of the tune.
