>soundstage is more akin to perceived spaciousness, not actual sound localization
tell that to VR ear speakers. you can optimize driver positioning and signal processing to achieve a variable sound stage with pinpointable precision at the cost of incompatibility with 2ch music.
what you're spending money on for soundstage in headphones is driver positioning and high frequency fidelity. same shit speakers use in combination with surround processing and crossfeeds (that you can still use with headphones, you just have way fewer drivers) to get perceptually further out instruments.
