best way to play/stream music through a house?

[Robert Godridge]

I'm just curious, what would be the best way to play/stream audio
throughout the house these days?
Does anyone know of any accesseable wireless speakers for example, or
streaming servers that can be used with them?
I'd rather not have to use i-devices but my wife does have an iphone.
I'd like to play flac etc too...
Just curious...
