I have the playbar and sub which I am quite happy with - output is PCM stereo out of connected external devices. Am contemplating 2 play1s to complete the system. My question which I have tried to find the answer to but to no avail is how does SONOS simulate the rear channels -ie is it simply taking the front channels and playing a bit quieter through the rear channels or something more scientific?
Also is there really much difference between the simulated 5.1 and actual 5.1. My tv is getting quite old anyway, so I envision I will upgrade it in the next few years anyway with one that will output 5.1 so am contemplating whether I should wait until I am done with my current tv.
