It is a matter of finding a scenario that you
are happy with. It would seem that the differences within the HD518/558/598 family are mainly in aesthetics and casing (drivers and cables are apparently identical).
So I may well feel good about having the HD518, knowing that the world of exotica will still be here tomorrow.
Re specifobsession not yielding true comfort: agreed.
Where is that perfection we all seek? Is it in finding the perfect amp to fit the perfect headphone? Is it in the moment when the experience of music fits one's yearning? Maybe the former is a vague promise of the latter.
Re high-impedence 'phones demanding significant amp upgradage: agreed, again.
Re the HD5x8 clan sharing identical electronics: that may miss some detail, like the HD558's full-body transducer tuning and its internal spatial reflector, meant for soundstage enhancement. (Hmm... that felt
Re leaving some exotica for the path ahead: Oh, yeah!
