My guess, no great controversy, is that option 1 would be the best move of the three. But are the restraints pushing you to bookshelves financial, aesthetic or space-driven? If you think there's any chance you might go with floorstanders later, like the M60s or M80s, then I'd give more serious consideration to option 2, with M2i's all around for now. (Although what the heck, having an extra pair of M22s if you upgraded would be sweeter than having an extra pair of M2s I guess.) I'd love to hear an all M3is set-up also. But your upgrade path is harder from the M3is to M60s ... and so option 1 seems better.
Just curious - why are you xing the sub over at 100 Hz?
