I always wanted a speaker that i do not hear, it was supposed to put the musicians in my room and have absolutly no coloration or any box sound at all
I've noticed that Magnepan owners are the most satisfied of all speaker owners. I caught the bug a few years ago when I heard a pair of 1.6's in a showroom, and promptly went home and threw my $700 satellites in the garage (I already forgot the brand) because I felt violated after hearing those glorious 1.6's

To my ears there's really nothing to compete with a large planar for the breath and hight of soundstage. That being said; planars are not for everyone
I've heard close. Legacy Whisper, JMLabs Utopias, and a few Wilsons I've run into over the years. The Whisper in my opinion matched the big Magnepans the closest in terms of transparency, detail and neutrality, but the maggies have a much more vivid and extensive soundstage, and are significantly cheaper. That being said I steer most of my friends towards high value, nice sounding dynamic speakers like Athena FS2's, Ascends', etc.
