This HD58X is hackable. Look at this, simple modifications will bring HD58X to have the same sound profile as HD660. https://diyaudioheaven.wordpress.com/headphones/measurements/brands-s-se/hd58x-jubilee-massdrop/

By the way, have you done measurements how the sound changes when you remove the grille foam?

Yes, no change at all, just like when the grille & foam is removed completely. magenta = stock, cyan = grille & foam completely removed (open backside)

freq res won't show, is like open back and closed back could have the same freq res but totally different sound. CSD is what u should look at, and yes when the grille & foam is removed completely it sound a lot different.
