Thanks shahkhan, Electrolite, annasoh323, and DavidA for the messages. Much appreciated! Great to know about the sound stage. It's been a while since I've used the 990s, so even if the soundstage is noticeably worse comparatively in games (both competitive and, of course, BOTW!) or certain recordings where stage is emphasized, I'm sure they'll still be a major step up compared to my current headphones! Their imaging is supposedly superb as well from what I hear. I'll have to check out AutoEQ, I appreciate it! I'm almost certain that I'll appreciate the high half of the "V" not being as pronounced with the 58x's. Would you say that the bass is noticeably lacking with the 58x's in comparison? I'm by no means a basshead, but I do appreciate a bass that you can feel when the music calls for it (especially the sub-bass). I'm coming from a pair of HyperX Cloud 2's (not exactly an audiophile's dream cans!), so as long as the 58x's bass is closer to the 990s than it is to my current headphones, I'm sure I'll be more than satisfied!
