Definitely stay with planners, I say.
I've owned Mag Tympani 1a's, II's, and SMG's. But I've come to prefer Quads. I've owned ESL 57's, 2805's, and 2905's. The 2905's are the best, with an octave more, top and bottom, but they are no more musical than the ESL57's. If you're on a budget, ESL57's can't be beat, but make sure that they are in good shape.
