I just noticed an article @ BBC about Goggle and their Chromecast Audio gadget, which for £30, will stream music (using apps etc) over wifi to your old hifi via 3.5mm jack or RCA connectors. It looks like it's a cheap alternative to Sonos and such like and if it comes with a digital output, a very handy gadget indeed.
