Chuck, forgive if this has already been mentioned; I didn't see it.
Why suffer the agony of losing some characteristics of sound that you love, forfeiting them for a different set of characteristics? Know for sure that you will lose several lovely attributes of sound quality when you lose the Maggies. It is not possible for other genres/tecnologies to replicate the sound attributes of a dipole.
Sure, you will get a new set of attributes, and some of them the dipole speakers cannot do. Be prepared for some let down and some excitement as you transition the system.
But why suffer? If you have the room and the means, own both! Have your panel and dynamic speaker, too! It's glorious to have different genres of speakers to swap out! Imo, best of all worlds in terms of speakers.
I sent you a message to discuss further, if you wish.
