what brand of amplifier for my situation?????

I suggest haunting a few Audio/HT merchants in your area and see what you like. It is very pricy, buy McIntosh has a great six channel amp out there that demands a listen.

Yeah McIntosh is good with your speakers. Also, Parasound HCA1206(not 1205), Classe, Aragon 8008x5(older), B&K(ok), Anthem, and other slightly soft on top amps, with warm body. The above mentioned are than. Also, the Pass X5 should do fine also I think, if a little more refined.
Otherwise tubes will do the trick all around.
Also, if you have reflective surfaces, you should consider making sure you have more controlled focused speakers, like Plannar, Horns, Dappolito's, THX, etc. Still, a few panels here and there would help you. Why not?!
