2. No. It's like tires. Do you care if there's 2 Dunlops and 2 Michelins? But the catch is two-fold with speakers. All speakers have a voice of their own. Mix, and you'll have different voicing at different locations. Does that matter? Not to me, I've enjoyed it like this for years, and I've HAD matched 5.1.
The other side of the "All Five The Same" is that in different locations in the room, you'll get different sound at the listening position. So if you have rare / vintage mains, don't feel like you have to scrap them to get good HT.
