Sorry if this is in the wrong section but I am never sure where to put hifi/ iPod/wifi qestions. I have just come accross an app for aifoil for my iPhone. would this let me play spotify and iTunes through my iPhone attached to a dock on my hifi if I buy airfoil for my pc? Just thought this could be a very cheap way of getting pc content to my hifi. I plan to get an airpot express in the near future as I can route it through my CA 740C DAC but thought this could be a good start.
