I did not miss it, and I am happy for Madfloyed that he finally found his bliss, but this saga was a bit strange one from the begging. Everyone that was in his place thought that they sounded awesome from the get go, but he did not (and that is perfectly fine, that is not the point). And didn't he liked the S5 in the same setup? The MPro are more efficient and easier to drive so why should it be an issue? All I am saying is that we are all very susceptible to all sorts of influences that have nothing to do with the sound of the product. We also get used to certain sound, and when presented with something unfamiliar, even if better objectively, we may reject it.
I actually suspect that that is what happened to Madfloyed, he just needed time to get used to greatness
Interesting theory, but I don't entirely buy it.
It's certainly true that having come from ported speakers (like you, cannata) there was some getting used to a sealed cabinet, but as a bass player it didn't take me long.
I wasn't totally happy with my S5's because of what I perceived to be a bass problem. I had noted that when I turned up the volume that the tonal balance changed and that the treble got louder than the bass (i.e. it wasn't linear). I wondered if this was normal for a sealed cabinet (since I hadn't owned one before) and started a thread asking about it. I am a lover of many types of music and could not play many types of rock/pop. Even the latest Mono box of the Beatles (highly acclaimed) was pretty rough at 90 db. I added a subwoofer and re-positioned the speakers to get the most bass I could. I came to the conclusion that with my somewhat open listening environment that I needed larger speakers. I wasn't interested in anything other than Magico. If only they had an extra 10" woofer I thought... they should make an S7! Meanwhile most of the time I was content and the only times I wasn't was when guests were over that liked to listen to rock/pop fairly loud and I found the sound to be less than stellar.
Incidentally, one friend (a woman) would comment that there wasn't enough bass and that she liked my previous speakers better (Wilson Alexias).
Well.. Magico came out with M-Projects and me not knowing that they would follow up with an S7, I robbed a few banks and took a leap of faith.
The M-Projects may not be as lean as the Q (which I've never owned) but I think they are leaner than the S series. At least with an underspec'd isolation transformer denying them full power.

At one point I switched back and heard how much warmer they sounded but also heard the differences in quality of the midrange and treble and knew that I could never go back to the S5 - that I had to find a way to make the M-Projects work.
Anyways, most of you know that I had an electrical problem that has since been solved. That helped tremendously. I still wasn't entirely happy until I made some other changes and I'm about to start a thread on that, but suffice to say that I am now really enjoying my system and I don't see myself ever parting with these speakers. They are capable of doing justice to all genres of music and that is very important to me because I listen equally to classical, jazz and rock.
I still have the S5's (anyone want them?) and I feel I should try them again (for fun) since I've never heard them with proper electrical power, but I can't stop listening to the M-Pro's... I am truly addicted.
