The Edition XS, ... is...... much like the HE1000, but with less veil in the mids- upper treble.
The HE1000 is the warmest of the HE - Series, and the XS is much like the original He1000s sound, yet, with the Stealth magnet option that codifies the treble response regarding the micro detail layering.
Ive been listening to $4000 Stealth's for a few days, just relentlessly, and i took a break, came back to the music with the Edition XS just to evaluate the headphones vs the Stealth.
Well. right away the XS sound good. They are not thunderstruck by the Mighty Stealth's. In fact they only sounded different, but never did they sound anything but good.
The Stealth's really have a monopoly on crystal clarity and instrument separation, but that is compared to any set of headphones.
