Macdadtexas,
I agree with getting what you like. My main point is that, in my experience, getting the same type and quality makes the sound more cohesive. There's a distinct sound to speakers, especially cones vs planars or electrostatics. The more similar the speakers the more they sound alike. And I think the resulting cohesiveness in tone and dynamics makes for better sound.
Chadnliz's system would probably sound best in HT with 3 Innersounds but that's not very practical or economical, which is of concern for him (them?).
By the way, I added a CC3 (with Magnepan 2.7s) and they work great together for HT. But all 3 need to be out from the walls to sound their best.
