Best amp for my needs?

I have a pair of ML Aerius 1 and am planing on getting a ML center theater, and add two rears and sides. Any suggestions on what would be a good choice for amp that would both serve for music and home theater? Or am I asking for too much wanting both worlds? Suggestions both new or used would be appreciated.If possible give options say from $1500 on the low end, up to $3500 on the high end. Thanks for any help.I am told these speakers will do far better with certain amps above others.
