Having read all the reviews and posts on the forums I am now sold on a sonus system,but which one? All my music will source from an imac.I have 3 zones which comprises 1 upstairs bedroom and two rooms downstairs one of which which incorperates an open plan kitchen. my main question is do i have 1 play 5 in each room downstairs an 1 play 3 upstairs. or is it better to have a pair of play 3s as a stereo pair? Or combinations of both. I have budget of around £1000. All ready have ipad2 so controller is no problem(although my ipad doesnt always come home with me but thats an issue for another day)
