...between buying Onkyo's HT-S650 and Onkyo's HT-S760. Due to the layout of my room, I don't have a good way to hook up any third rear satellite - so I'm thinking I only need a 5.1 system really. I understand you can 'turn off' the third rear satellite on the 760. However - for the money (only about $65 more) - I can buy the 760 instead of the 650. I've got to think there's other features/benefits to getting the 760 instead of the 650 - but maybe I'm just assuming too much. Better speakers ? Better receivers? Better inputs ? Should I just save the cash and buy the 650 or are there compelling reasons to go up to the 760? After reading here for awhile - I know this is the right place to ask. Thanks much.
