Hello i am new to this forum and not quite sure how it all works. with saying that if anyone has any tips on how to post better and clearer please let me know. My largest issue i have is i keep wanting to upgrade my surround sound and stereo Currently i have an onkyo Tx-sr506 receiver which sounds fairly decent but i want to upgrade to something that will be able to run the audio through and hdmi audio return. I am currently running optical audio from the tv to the receiver and i feel it is loosing sound quality from when i run it directly from my Playstation 3 and my U-Verse box, there are two optical inputs but i like to use one of them for audio from my laptop. I am primarily watching my movies on Netflix but i notice the audio is much clearer from blu rays on my playstation. My speakers currently are Boston Acoustics MCS 160 5.1 And i have a VIZIO E420d-A0 42 inch led smart tv however i also have two sets of bose 301 series IV and a set of series III 201 i am a college student so i have a fairly restricted budget but i am also willing to sell some things to upgrade my current system any advice?
