I think your tolerance for treble is insane. That's where I find the EX1000 a mess and unlistenable. The 7550 fixed that issue but doesn't produce the whole sound of the H3 for me. I can hear that its consumer oriented sound but for someone with stricter preferences, it hits all the areas. It might not be for the purists.
So vwinter likes flaming hot daggers in his ears while pouring a be bottle of Louisiana Hot Sauce
down them too? And that's describing the EX1000's treble mildly....
