I'm new to the whole HT experience. And I have been looking at different receivers and the whole experience is overwhelming with THX, DTS, 6.1, 5.1, 7.1. I'm lost. Can somebody help me with what I should look for in a receiver. All I want it for is movie watching. I have Bose 301 older version. Any help will be great as i am moving to a house soon and want to get a good receiver for my HT.
