I am looking for a newer surround sound system. I currently have a Sony STR-K790 HTiB that I purchased a few years back for around $150 (I know its terrible). My budget is around $500, I only need 5.1 and do not want a dvd player, the main use of the system would be for Blu-ray watching. I will be connecting it to my Panasonic TH-42pz80u, PS3, Xbox360, HD DVR, and maybe my pc. Do you think I would be better off buying pieces or another HTiB? Also my current set up only has 1 optical input, I would perfer atleast 2 unless hdmi audio comparable. If need be I would consider using the sub that came with my str-k790 for the time being and buying a new sub later. Any help would be greatly appreciated because I dont have any idea where to start. Thanx.
