Hey guys, im a tech guy but i was never really into audio stuff, i dont know to much about the good sounds investments etc. If anyone here can help me a bit i would very much appreciate it. I have the Xbox one and an LED vizio (dont know if that means anything for audio help, it does also have an optical port). Im looking into getting those Sonos Hifi speakers, im looking into the sound bar, as well as what they call the play 3 speaker (2 of them). Anyone know about the sonos speakers? are they worth the money? Also, whats the whole thing with the 5.1 and 7.1 sound, i see alot of talk about it but i really have no clue about what they mean. If anyone can help me it would be awesome, thanks alot!
