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

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!
Following is from the Magnepan site.

If you want to climb to an even higher level of performance, you can move up to a better model at a Magneplanar dealer in your area for up to a year. Depending on the model you purchase, you can receive up to full credit from Magnepan for your MMGs.
The trade up program is not available for the 12's, you have to go up to the 1.6's. BUT, there is a 60 day(I think) window were you can return them for a full refund.

Buy the MMG's save for a couple of months and then if you want to upgrade just send the MMG's back.
The MMG's deliver a lot of bang for the $$. The MG12's do the same but give you more of everything. I own the MG12's and am still smiling. IMHO the Mg12's are woth the extra $$.
