As many have said, the MMG’s are one heck of a speaker for the money and otherwise. I surely agree. The same can be said for the .7’s, which, for me, are a considerable improvement. Sound stage is larger, especially side-to-side, with greater detail, clarity, a bit more depth, and better, more "effortless" bass response. I feel no need to augment them with subwoofers.
Overall, there is simply, for me, more "planar magic." I also found the .7’s easier to set up than the MMGs. As we all know, much in this wonderful, crazy hobby of ours is YMMV. In this case, I do think one gets what one pays for, and then some. Kudos to Magnepan, a great American speaker company.
I’m very pleased.
