Sorry I could not help you with your logitech problem in that last post. I had to cruise the internet to see how it worked.everything is set up ok but its still not working when i do a 5.1 test every speaker plays ok except for the center which is weird as the subwoofer works(If I'm not wrong they are on the same cable).
i am not an expert. maybe what murabi wants is a suggestion what you would buy with his budget. out of the 7k budget he is willing to spend 3.5k on speakers (not sure if that is including the receiver or not). you mentioned the onkyo receiver is nice. so maybe one of those w/o the speakers and then attach 8 speakers of what to it? 7 of the same and a subwoofer? onkyo or different speakers? maybe that what he needs - list the parts for it w/ model numbers - and he can see if he can find them and agrees with pricerange ???... I recommend just sticking with the standard home theater components, but thats just my own opinion.
You have a 7k budget, why are you looking for cheap hardware deals?
