Magnepan MMG or something else

I had MG12's in my 13 x 14' room and I initially drove them with a modded Dynaco ST 70. Excellent sound. I wanted more power and detail and I purchased a Moscode 300 and AVA Super PAS3i (VA design not Dyna) and the results were excellent The MG12's opened up and the sound was better than I ever imagined. The MG12's were about 41" from the back wall and 22 inches from the side wall. So the speakers were nearly in the middle of the room. Not good! But once I hit that sweet spot that wonderful midrange, tight bass along with sweet and smooth highs the sound made me smile. I had several audiophile friends tell me it didn't get much better than that.
I then added 1 Dali Suite 12" acoustic suspension model 1.2 subwoofer. This gave me more much deeper soundstage than I expected. With the sub in place the midrange opened up tremendously. And since I didn't have to deal with boomy bass I added another Dali Suite 1.2 sub. At this point you couldn't pry the Maggies from my room until one day I need more space in my room My listening room was now my office and I needed more space. I purchased a pair of Spica TC 60's to compare to the Maggies. They were so close in the their presentation of sound but the subs blended oh so wonderful. I contacted JB (designer of the Spica speakers) and he assisted me in setting them up. Once that was done things were pretty even and the Spicas gave me much more space than the MG12's. I ended up keeping the TC60's because of space limitations and I sold the Maggies and the Moscode. Spicas are Tri Wired which gives me a wider and deeper sound stage and it adds a level of refinement that is scary.
With that said the Maggies simply played louder and with more power but the TC 60s were at that time only the thichness of thin wire behind them at that time. They don't require a big beefy amp and that had alot to do with my decision. I added a VTL ST 85 to the system and it's sweet.

I would suggest that if you are adding a sub,get two.Many will argue that only one is needed,but the other will add more separation and more uniformly load the bass.Akin to a true full-range set of speakers.I don't believe the claims of non-directional bass below 100Hz-there are left-center-right ambience cues in the low frequencies.

Shortly afterwards I bought a 2nd Dali Suite 1.2 sub and I was in hog heaven.

I purchased a pair of Spica TC 60's to compare to the Maggies. They were so close in the it's presentation of sound but the power with the Maggies was better. I contacted JB (designer of the Spica speakers) and he assisted me in setting them up. Once that was done things were pretty even and the Spicas gave me much more space than the MG12's. I ended up keeping the TC60's and space limitations were the reason. The Maggies were more extended on top but with the right wire they were wonderful. I ended up with Vampire Wire 12 gauge hookup wire for the speakers. My Spicas are Tri Wired and gave me additional refinement and depth in my little room.

With that said the Maggies simply played louder and with more power but the TC 60s are only the length of a wire behind them. But they don't require a big beefy amp and that had alot to do with my decision. I added a VTL ST 85 to the system and it's sweet.

I have 3.6's, and had the MMG in the same room. Spring for the difference, get the 3.6, it is better in every way except price. The MMG was too small sounding and not detailed like the 3.6.

I had a Fiat 500 in my garage, not nearly as good as my Ferrari though both made in Italy.
