Fidelity is also a factor, and while I know the X1 is probably amazing, I'm sure it isnt a D7000, LCD2, SR407, ESP950, etc. in terms of refinement. I have had a good taste of higher end cans, and I can tell if something is lacking. I'll treat the X1 as it should be treated, a mid-fi can with a sound signature that ticks many boxes.
The Kingsound will apparently have both the electrostatic refinement as well as a sound signature suited to my tastes.
