I have owned the Sophias and now own the 7's/WATCHDog combination. I agree with Keithr regarding the 6 vs 7 comparison, but would add that the 6's upper bass was thrust forward in comparison to the 7's and the soundstage of the model 6 was much more central and less wide or layered.
In the context of my system, the 7's were demonstrably better than the Sophias in the realm of scale, soundstaging, micro dynamics, harmonic content and pitch differentiation. The improvement in these areas afforded by the 7's over the Sophias and 6's are not subtle, and were easily worth the extra money--to me.
And yeah, Ferrari Blue sounds cool....
Happy listening!
