I have a pair of 3000s and I like them, they have the best high mids I've heard so far. I'm also listening to Piega with coax ribbons but the 3000s ribbons have much more body, the Piega sound is thinner, more detailed and extended but the 3000s ribbons have such a nice body, I guess that's because of their size. As for the mid-bass driver, it can be better. Maybe the bigger cabinet of the 7000s are helping the woofer but in the 3000 it's not that great. They need a high current amp or better, two amps.
