Hi guys 
I'm an electrician and has basic knowledge of audio, I've spent the last 2 years building my dream home and I'm not sure what audio to put in my house, I want 4 in wall speakers in the lounge + (sub?), 2 in kitchen (reason I say in wall and not ceiling in limited space and bedrooms above.)
then a full media room setup
also outdoor speakers
I currently have a lot of Sonos stuff and was going to buy the Sonos architectural in wall speakers, I went into the listening post in Christchurch they didn't rate them that much and were pushing me more towards the Origin Acoustics Composer C67

Im after a non-biased opinion on what I should go with a budget of around 10-15k 

Welcome along Nikki. Some background: Ive spent 40 odd years building up my system to where it is now and would love to have your budget to spend on gear !. I have no personal knowledge of the type of system you are talking about though I have been to friends places where they have Sonos and I would rate those systems as being OK for background type listening but not the sort of thing I would sit in front of for enjoyment. I fear you may be in the wrong place LOL.

I assume your media is all streamed ? Hopefully someone else with some knowledge of the type of system you envisage might pop along.
