Teeshot,
I used to own the M5 speaker and I have listened extensively to the Q3 and Q5. If it was me, and you have a larger room with top notch amplification, I prefer the M5 to the Q3 (anD perhaps the Q5 to the M5). While I agree to some degree with Peter, I find the sound of the Q3 to be a little lean sounding in the lower midrange and mid bass in comparison to either the M5 or the Q5. After longer listening sessions I found that not to be to my personal preference. The M5 to me was overall the better speaker.
