I need a new HT speakers

I would like to purchase a Home Theater System and I don't know what to buy. I hear that separate components are a better choice than a AV receiver. I have a budget of about five thousand dollars. I like receivers from Denon, Yamaha, and Pioneer in this exact order and speakers from Paradigm or from any another reputable manufacture.

I would love to buy a 5.1 or 7.1 amp and a good sound processor for a cleaner sound. Which brand should I be looking at? I need a HT that can last me for the next five to ten years.

Can someone in here put together a system for me. I'll be using my HT for 50% music and 50% video. I will appreciate any recommendation you can offer.

Thank you very much for your input.
P.S. I already have a sub (M&K V-125) and surround sound speakers.
