I'm throwing in a third option. I briefly considered the Sonos 5.1 system when I agreed to give up discrete separate speakers after moving to a new house, but was put off by the fact that it can only decode dolby digital 5.1. My TV can send 5.1 over optical as well as Dolby and DTS lossless over ARC. I decided to stick with a wired system. I first tried a Vizio S5451w-C2 54" 5.1 soundbar but was ultimately dissatisfied with it after a year of use. It sounded decent but lacked clarity in the voice channel and dynamic range, as well as a shrunken soundstage.
I had kept my receiver, sub, and speakers in mothballs all last year. In the spring I acquired a Definitive Technology Mythos SSA-50, so brought out the receiver, sub and two satellites. The soundbar itself is 5 channels and generates a soundstage equivalent to my old LCR speakers, as well as some surround effects. The satellites I use for surround back channels in a 7.1 configuration like I used to have.
Now, back to the point at the beginning of this reply. There is a palpable difference in the sound of DD 5.1 and DD-True HD lossless. I also have the option, which I am experimenting with, to take advantage of Atmos soundtracks. I have heard the Sonos 5.1 system demoed at a friends house but I much prefer the sound and flexibility of my semi-wireless setup. The soundbar is wired to my receiver but the subwoofer and rear sats are connected to my receiver using Rocketfish wireless kits.
The system I setup can be put together for far less than the Sonos 5.1 system. Well under $1000 if you are judicious. I got my soundbar on ebay for $350 for example. One could get a good mid-range receiver either new, used or refurbed for $300-$400, as well as your subwoofer and satellites for a few hundred more. You could always spend much more but you don't have to. Incidentally, I do have two Sonos play 1's that are excellent speakers in their own right. The only thing I don't like about them is, as someone else mentioned, the necessity of using the Sonos app.
