If you really are in a place where there aren't any sources of interference and the devices are within range of each other the wireless should work great.
I've tried an Airport Express both ways and there was only one problem with going wireless, when I turned on the microwave in the kitchen, the music stopped. I hardwired it to avoid that, even though it was only an occasional problem.
