I assume you're criticizing my over-generalization in using the expression "Audio-Technica" house sound -- fair enough.  But in broad, sweeping terms, I was just trying to get rid of the Grado house sound, so inasmuch as it's not a Grado, there you have a house sound.  So, to synopsize:
 
ESW-9:HF-2::all A-T's:all Grado's 
 
...meaning it doesn't have the Grado forwardness that the HF-2 does, which admittedly, it doesn't as much as other Grado's. 
 
Better?
