HE4xx vs HD58x does the 4xx sound noticeably better? particularly if I am looking for Airy Open Big Sound Stage Speaker Like Experience?

Can anybody here actually explain why rtings.com places the HD58x significantly higher in terms of sound quality over the HD6xx?

I read all the scores and the HD58x simply trashes the HD6xx in every department. Yet the HD58x is so much cheaper? how can this possibly be? shouldn't the HD6xx perform better if it costs so much more?

This has had be wondering if to still buy a HD6xx, but since both the 6xx and 58x scores mediocre in sound stage am just thinking of getting the HiFiMan Ananda since that is the second best scoring headphone on rtings when it comes to sound stage.

I am just suspicious of the longevity of the HiFiMan Ananda being Chi Fi, but at the same time the HD800s is just too expensive. Decisions decisions.....

I also wanted to get the HE 4xx But There is no review of it on rtings.com and I am not entirely sure if it is indeed a he 400i, it scores decently in terms of sound stage very decent actually as in WAY better than HD58x and HD6xx

I don't mind spending the $600 for some good Hifiman but the longevity of a Chi Fi Product like it has me very worried, which is why I am considering HE 4xx cause if it breaks well ooh well was only $130 but I don't want to buy the HE4xx and then be meh this isn't much better than my HD58x what a waste of money. You know?
