All who want to go wireless with their "old" AVR or stereo receiver music without sacrificing quality, are in the right place. I had long been looking my laptop (Win 7 and iTunes) to wirelessly connect with my old, but still very good denoch Yamaha stereo receiver. Had already two effective systems tried, but every time they went back by return mail. Not so with the AirPort Express. Configuration time were about 5 minutes and the result is great. I can not tell the tonal difference between the AirPort and a normal cable connection. However, it should still say to that one on the Apple website still has to download the "AirPort Utility" to configure a good piece on Windows PC or to connect to existing WLAN allow.
