I have extensive experience with Magnepans dating all the way back to 1976. Yes, they are incredible and incredibly sensitive to their room. If you have a Maggie-friendly room there's nothing that can touch them even remotely close to the price. The best Maggie setup I ever had was a pair of MMGs (predecessor to the LRS) run in a perfect Maggie room off of a circa 1980 NAD 7125 receiver. That system wouldn't play headbanger loud, but at normal listening levels it was superbly balanced, threw a huge soundstage, and was just fun to listen to. If your room isn't so friendly, nothing you can do will make them work. If you can't get at least 3 feet on each side and 2 feet to the back wall (those are minimums, not optimums), then forget about Magnepans. I have my current .7s for sale, simply because I lack a suitable room. That said, If you simply want 'more' Magnepan, then the .7s will provide that, and the 1.7s even more.
You don't mention subwoofers, but I would also consider the REL t/7 or t/9, the SVS Micro 3000, and KEF KC92. Small fast, tight subs that blend well with Maggies. Finally, I would put them on risers, at least 6" to 9" to clean up any thickness in the lower vocal range and to raise up the soundstage.
