I have .7s. I also have a pair of MMGs. I'm still tuning this system so I can't make a judgement yet but Stereophile magazine rated the LRS as class B one grade up from the .7. So it seems the little LRS is perhaps a good choice then if you want you can move up to a 1.7 or preferably a 3.7. But the key on any Magnepan is to get you ear on the center of the panel.
