Technokid, the mids on the HE-400 arent bad, and i never wanted to imply that. But they are recessed. By "how much" is subjective so no point going into that at all.
My strongest gripe about that recession is some games where i miss a specific part of the music that is clearly pressent with my speakers (anywhere from my laptop speakers to my Z-5500 logitech).
You can still "hear" those sounds, but they are greatly overshadowed by the bass and treble, and the action feels a lot less Epic or Dynamic if you know what i mean.
I mostly noticed this Mass Effect 2, and while its not something that is constant or even happens often, its certainly something that i notice.
In other words, the Signature is not "exactly" what I want (but it is quite close).
I never said you thought they were bad I was just stating how I felt about them.
