Looking to get set back up with at least 5.1 surround sound in my home theatre. At the moment, things are pretty simple - Almost all video&audio going from my Roku to my TV using the built-in speakers. I also own a set of 5.1 Boston Acoustic speakers that sound amazing. The receiver I used to use to drive them died a couple of years ago and I also no longer have any speaker wire. So... do I invest in a new receiver and set up the perfectly good (really, more than good - the sound is awesome) speakers I have now in a wired set-up? Or, does wireless win? Sonos seems to be the leader here?
