Let me elaborate on what I meant by the 2.7's sounding "congested". First of all, my comment said it was congested on "complex musical passages". Specifically I'm referring to large scale orchestral music. The resolution of individual instruments in an orchestra is better on the 3.7's. The 3.7's simply handle this kind of material better without sounding strained or congested, probably because its dynamic range performance is superior. But that's what you are paying more for.
I should repeat that I listened to both the 2.7 and 3.7 in the same room with the same electronics, so those variables should be mostly eliminated in comparing the two speakers.
It is possible that there was something wrong with the particular pair of 2.7's I auditioned, but I can only report what my ears heard. I'm guessing that if you really like your 2.7's, then you will absolutely love the 3.7's. I do also agree with one of the comments already made that the 3.7's really need a larger room to "bloom".
