Wife and I are currently building a home (walls are framed). Our anniversary is coming up shortly and as a surprise gift I'd like to have a whole home audio system installed... I think? Kitchen, living room, patio, and master bed. The biggest hurdle at this point is that I have no idea what people do these days because I'm disinterested in most tech. Are systems still hard wired? Is everything blue tooth off from some kind of hub? That type of stuff. Not looking to break the bank but would be will to spend a few thousand dollars if it makes her smile. Any direction/help to at least get me up to speed on how this stuff is done would be greatly appreciated.
