I heard the Q3s at CES and was stunned. Excellent speakers in every way. I've heard a variety of Magicos at shows over the years, and these were the most impressive given the price. A vast improvement over the V3s, which I think are great speakers.
The Mini Qs were in a side room, not playing, and they're not as visually appealing as the Mini IIs but I'm sure they will sound much better.
I own Dynaudio C1s, which I love, but the Magico Q3s are in a completely different league.
