I have the LRS’s and am using a Kinki EX-M1. Maggies sound far better in the sweet spot, therefore Im not sure they work well in q home theater application. Also, if you are just worried about 1 person sitting in the sweet spot, you don’t need a center channel.
I think Bryston would be a good match for magnepan. I really want some 1.7i’s after living with the LRS’s for a few months. I really love the maggie sound!
