Amp for Magnepan 3.1 speakers

A friend of mine is asking my advise on what to get for his Magnepan 3.1s. He uses it mostly for home theater. Tubes are not an option. I want to get him a neutral amp w. decent body and high power that will be "turn key" for his use. A preamp is needed as well. He has rear speakers but they are not Magnepans. He needs probably a preamp / processor of some sort and an amplifier for the front. His budget for amplification is probably close to $2000 and he likes to buy used. I know what to recommend in terms of tubes but to find SS that is neutral with enough power anything I think of is too much money. Any help would be appreciated.
