Ok, the idea of monitoring is to have accuracy.
So, to have accuracy you have to have neutrality,.... so that you are getting the sonic info delivered as its written instead of getting it as its rewritten by artifical design.
And with some headphones, such as the Senns we are discussing, they are not designed to be neutral, they are designed to supply more low mids and enhanced treble.
by "artificial" stereo, what im explaining is that headphones by design take the information they are fed by the sender and they place it more on the left and on the right, artifically.
This is by design.
This is why a really good headphone amp, ...like a Headroom Max,... will offer you a "blend" switch that allows some of the hard left/hard right headphone soundstage aspect to be a bit more center blended in your head as you listen.
See, you hear in stereo.
This means that your ears , say the left one......gets audio information from the right side and mixes it in with the left side info its picking up, and vise versa., as that is the way our ears pick up sound as processed by our brain. = all around = perspective.
In other words, the left ear HEARS and Perceives more then just the audio information that is on the left side..
This is the perspective that is lost when you use headphones, because a set of headphones is a closed audio delivery system.
In headphones, the true audio soundstage is marginalized so that your ears, which are each in a cup, are getting what the headphones are seperating as "left" or "right", which is not a true stereo aspect as you would hear it without headphones, and in this, you are getting artificial separation and thus not a true stereo aspect, when you use cans.
What really good cans and a good headphone amp do best is let you see deeper into music the small details which otherwise would take an extreme high end $$$$$$ hi res audiophile system playing in a perfectly tuned room to show you.
What you lose when using cans is some stereo perspective.
Its a fair trade for inner details, i think.....however, when it comes to mixing on cans......well
