I don't think your SC1 center is going to match well with the ML. In fact, I don't believe in center channel at all. I found that in most rooms, even you use three identical speakers across the front, the surrounding of the center channel is so different from the two front speakers that it is impossible to achieve a perfect match. Unless you have a very large room, I perfer to just turn the center off. It sounds more natural to me.
In terms of multi-channel amp, I had used a Theta Dreadnaught (5x200w) to drive my SL3 with great results.
