Magnepan MMG or MG12?


I have enough to buy the MMGs now, but I am concerned that I will be left wanting and upgrade soon. Can anyone speak to the performance advantages and disadvantages of the MG12 vs the MMGs? Is it true that you get 90% of the MG12 by buying the MMG? I have the money for the MMGs now, but I will have to save a little longer to get the MG12. I will be driving them with a vintage Yamaha M-65 amp that is stable down to 2 Ohms...I think its rated at about 220 per channel at 4 Ohms. Thanks for your thoughts

Magnepan has a trade-up program. You would have a year to trade up to the MG12 if you aren't satisfied with the MMG. Check the Magnepan site for info on trade up options.

MG12 smokes the MMG, regarding the trade in program its only applicable to the 1.6's and up. Raising the MG12 6 inches with aftermarket stands also increases the performance.
I was in the same boat about 2 years ago. I didn't hear the mmgs but auditioned the mg12. Ended up finding a pair of used mg12s (about a year old) for about $750. I really enjoy these speakers!
