I also agree with Preproman in saying that the Emotiva is a very aggressive amp, very engaging, but not relaxing at all. I think the dynamic range is pretty explosive in the bass and treble which might give the impression that it has a v-shaped curved because the treble and bass sounds like they're hitting hard and fast, but in actuality they're not more accentuated. Hard to explain.
Oh yeah I also agree about the extension. This amp is definitely not rolled off in any direction. Hits you from very high and also very low, also giving the impresson that it might be v-shaped, but it is not v-shaped. Hard to explain, but yeah it sounds neutral to me, just aggressive and revealing.
