Although I have no experience with the Q3, I have owned the Mini II, and am very familiar with the Magico sound. It is a good speaker with very distinct character. However, after some time I found the speaker to be colored and fatiguing (Halcro and dCS gear). I found complete hapinees with the Vivid speakers. Very natural and realistic presentation. Even the small speaker, the V 1.5 is a world class speaker.
