I would recommend you get a Sony STR-DA997 for several reasons. First of all, it's $ 349 at Bhphotovideo.com. Second, it has 7.1 capability, so you can upgrade later as you see fit. Third, unlike Kenwood and some other brands, the middle line Sony receivers last forever so you can move it to a bedroom if you decide later to get a new receiver way on down the road. Fourth, they are very easy to operate and fifth, of course, is that you can use any or all of the Sony remotes on all their other pieces of equipment without any addiitonal programming. Wives usually appreciate No 5.
You will get very good sound and reliability at a budget-friendly price.
