I was wondering, my speakers are not shielded so I have them away from the tv. Should the amp (reciever) be kept away from the speakers, tv, dvd, or any of the other components? Also, like everything is very close so I was just wondering if there are any other units/components that would interfere with each other, I'd like to find out before I have a problem, anyways, the other question is I think I need a surge protector but I think there might be one on the powerbar, assuming there's one on the powerbar is that one sufficient, or would I need to go and get a specific type or kind of surge protector? Also, is using powerbars, especially ones without protections safe? Thanks
