I agree the MMG. I'm driving my MG12's with a modified Dynaco ST 70. I have also owned the Titus. The Titus is fast and sounds very good but it was more forward sounding in my system than my MG12'2 ever were. I kept the Tituses for about 3 to 4 months and they were gone. My Spica TC 50's were so much better than the Titus. But, my MG12's are even more special. Big sound stage, clear and musical.
I have had speakers that cost as much as $5000 and I still prefer the MG12's. The MMG's and MG12's are cut from the same cloth and will have a similar signature. Actually the 1.6 is from that same cloth but everyone says it's the most dynamic speaker Magnepan has. Since you have a sub already have you thought much about the wall mount Magnepans meant for Home Theater? The only go down to about 80 Hz and the sub can handle everything down' below.
