Is this going to be your first ever system or have you already developed some "insight" through listening to even a normal run of the mill Home Theater or stereo ( or even Hifi ) system? Does the Sony A/V receiver have a subwoofer out ( LFE ) output or will one have to buy a sub with speaker input and output terminals ( not all subs have this ) to connect up a later addition of a subwoofer to make all that thunder and rumbling without which a movie is left wanting? What will the SAF ( spouse acceptance factor ) be regarding floorstanding or stand mounted ( stands cost money, maybe divert this cost towards better floorstanding ) speakers ....... We want to help you, but we need some of your biases and taste in music too.....What fun!!!!
