A big congratulations, Madfloyd. I remember vividly encouraging you to get these because I knew that it was likely going to be the only way that I would ever be able to hear the M Project in any setting, much less in a good friend's home system. I just never thought you would go through with it. So I jumped at the chance to help you uncrate them and watch the movers lug them into your listening room.
I agree with Madfloyd's initial impressions and will just add a few of my own. I understand that they will need 400 hours or so of break in and that the initial positioning is not yet ideal, but with those caveats, I have to say, hearing these M Projects has been sort of an epiphany for me. Today was the first time that I have heard symphonic music through a stereo system sound remotely like what I have heard at the BSO or the Vienna State Opera. The scale was huge and the sound was completely effortless and natural. Specifically, the sound was ultra coherent, seamless and tonally balanced. All I heard was the music, no system, no boundaries. Dynamics, macro, but especially micro were better than I've heard from any system, including the Q7 and Wilson XLF, both of which were in purpose built super demo rooms.
Madfloyd wrote of energy. I spent four days listening to rehearsals at the Vienna State Opera from the edge of the orchestra pit - full orchestra as well as individual solos. I also listened to cello and piano sonatas in a private living room four weeks ago. I have never heard that sense of pure energy exploding out of a speaker system before. It was startling, very realistic and yet relaxing. Absent was any sense of glare or harshness or discontinuity. Incredible detail, yet absolutely no fatigue. Very clean, smooth, detailed with vanishing levels of distortion, just music. Clean is the one adjective I would use to describe live symphonic music. This is what I heard today.
I should add that from initial impressions, the M Project is voiced to sound more tonally neutral, like the Q series rather than the slightly warmer and impactful bass of the S series. It seems to have a more extended and smoother bass than the S5. And the tweeter, which has gotten some attention, is truly extraordinary. It, too, is very smooth and extended, yet one is hardly aware of it, because it does not draw any attention to itself.
My previous two favorite speakers are the Mini 2 and the Q3. Both are extraordinarily coherent and tonally balanced with great dynamics. If set up properly, they can sound very natural and convincing, but compared to the M Project, they just sound small and medium, respectfully. The M sounds HUGE by comparison, with even more resolution. It was an experience I will not soon forget. I can't wait to hear them again after they are more broken in and positioned on their footers.
These impressions are early and based only on listening to acoustic music on vinyl. No digital, pop/rock or amplified music.
Great choice, Madfloyd. What an incredible speaker.
