Looking at options to get rid of all my 5.1 speaker wires. I have an Onkyo TX-NR709 AVR running to 5.1 surround speakers an LG 55EC930V Oled TV, with inputs from a Bluray Player and a Freesat box (plus a now obsolete iPod dock). I also already have 2 Sonos play 5 speakers that I use in other rooms. I have a feeling I'll find out my AVR would be made redundant by a sonos 5.1 set up but I wonder if I should leave it filling the gap in the furniture that I had custom made for my set up, and feed the output from that to the playbar/playbase instead of having everything go through the TV? Is there any sound quality advantage? The other thing I was wondering is that this might allow me to still have my existing powered subwoofer instead of getting a Sonos sub (no need for long wires on that one). I was then also wondering if I could keep my centre speaker in the cabinet under the TV too for an even fuller front sound, but that may be a bit daft. The AVR seems to have a baffling array of capabilities that I don't understand, but I'm wondering if there might be syncing issues if I keep the sub and the centre and also feed to the sonos 5.1, or if I even can do this in the first place? Final question... I almost always stream music from my mac or iPhone to my existing play 5s. Would I need anything else to bring the sonos 5.1 set up in for music from these devices in the full house set up? Forgive my sketchy understanding - trying to work out my shopping list for the house move and what, if anything, needs to go.
