alfredo, I would hope that you could listen to the Rotel RB-1090 and the Aragon 3002. On paper the Rotel looks to be the better amp for the big Paradigm front speakers..but does is sound better? I can't answer that, I hope someone else that has tried both with your speakers can give you a little help. After you decide between these two..pick the five channel amp of the same brand IMHO. I would also have dedicated circuts installed for your system.
