Have you listened to the K10? It is hard to imagine the difference betwen the two with just their respective graphs. Encore is more neutral and detailed. K10 has a more elevated bass, perhaps v-shape sound. Both are equally good, one is more analytical, another more 'fun'.
I agree with your general assessment, but I wouldn't say the K10 is v-shaped. Far from it, actually. I find the K10 quite mid-centric, in fact. It's definitely one helluva fun IEM.
