No, I bought the Magneplanar 1.7s and couldn't be happier. I have enough listening space to have them about 4' out into the living room. I took my wife with me for final auditions and we played one of her favorite pieces, the opening to Mendelssohn's cantata, Elijah, which has full orchestra and a chorus singing 8 different parts. She could easily differentiate the inner voices on the Magnepans but not on the Triton Sevens. That settled it for us, and the imposing 19"x65" panel size didn't faze her at all when it comes to the music. She's a keeper.
I have heard the Regas several times, however, and they have a very natural presentation and good in-room dispersion.
