I have a friend looking to get into home theater. He has a total of $2000-2500 available to spend, so I'm thinking $500 for receiver, $500 for sub, $1000-1500 for speakers. He does not have room for a 7 channel set-up. He knows he needs to go out and listen to his options, but I'd like to give him a place to start, as far as brands and models. I am a fan of Paradigm and JBL, and I am sure there are online options too. Thanks for your help.
