I agree with you. I do not know how to read audio graphs but I will tell you how its like in plain english for avergage joe viewers.
First, the HSU hits you with a bam with the huge soundstage. Thats where you go "wow" because its so large and full, its not like neutral speakers. You think home theatre audio set-up, and in the shallow aspect of things, its a no brainer you would start wanting a Theatre-like sound. But the bad thing about this is, can you really live with theatre sound 24/7? Some sounds like sports and normal broadcasting you want a LIVELY sound. And if its full and the soundstage is huge ADDED with warmth (Hsu) then itll be like watching live television in a theatre. I think eventually you will get sick of it.
The HSU's are a closed system speakers.
The more laid pack and neutral speakers (CBM- 170SE) does not wow you at all. It somewhat puts a smile in your face instead
With laid back speakers (CBM-170SE speciafically), I figure since the fullness and the wide soundstage is somewhat replaced with airiness and openness the speakers emphasized on detail and clarity. I dont think you can have much clarity plainly speaking with warmth. All the voices and tones are DOWNTONED, so ofcourse its not going to be as detailed clear.
Warmth of sounds always has a little bit of BUZZNESS addedd to the tone, therefore, detail will get comprised as well as clarity.
Clarity can only come with openness. And vice versa, you cannot have warmth with openness (airy).
I think for a person that watches T.V once or twice a week and strictly movies, the HSU's will be perfect, otherwise one should look into the Acsends instead.
The WOW factor the warm, big, forward speakers bring will be gone after the first few times and eventually youll be with a closed system without much dynamics.
