Ive looked at the apple tv but this seems overkill as the laptop is in the same room so would want to control the menu from the laptop and not a tv, the squeezebox seems a bit expensive and again a bit overkill, the airport express looks like a good deal but it looks like it only has a 3.5mm jack but i would want to go optical into my dac... Also i would want to stream spotify aswell as itunes, would the airport express stream spotify aswell?
