....I'm looking to put together my first home theater. I have a few questions for you guys if you don't mind. 1. What's the added benefit to seperate tuner & amp? If the benefit is good enough, what receiver should I get with upgrading in mind? 2. 5.1 vs 6.1 vs 7.1? Not looking for a huge debate, more just your preference. And what brands? Thanks for the help guys.
