Hi Peter,
Again, continuing with the thought in my reply to Davey, I think people hone on what they like and find realism in... There is something about speakers that have a single driver across the entire range. If you are used to that sound, everything else sticks out. Tastes are learned. Obviously, people readjust their tastes with new experiences. Coca Cola tastes Weird to someone first trying it - until they learn to like it. And remember the looks on the faces of freshmen who are new to alcohol in the first few weeks of college. That grimace is gone by spring, as they embrace the bitter taste...
Unfortunately, these musings are irrelevant to the question of the Mini II sound coherent or not.
I listened to the mini and q in the same room, and I am familiar with full range stats... Ack maybe right about the incongruities of the Q, but I think it's much better than the mini...
Here's the truth:
1. The Mini II, when expertly set up as Peter did, sound very coherent (I agree with Ack).
2. The fact that you heard the Q3 and Mini II in the same room is, in itself, irrelevant. Speaker set-up is everything, and obviously there must have been problems. One speaker may have been set up well, and the other not. And if you drop another speaker in the same position as the first one, and expect miracles, this is often wrong. What may be an optimal position for one speaker, may be a sub-optimal for the other. Near the top of the list of audiophile mistakes 101.
(And if both speakers were in the same room at the same time, instead of removing one from the room while listening to the other, this would be even worse.)
