I've been using Airport Express for this purpose for several years now without any problem. My AE is one of the previous generation (802.11g) models, set up to join a wireless network controlled by an Airport Extreme base station (802.11n). I stream from both my iBook (802.11g card) and my iMac (802.11n) on a regular basis. I also stream occasionally from my older swan-neck iMac (802.11b card) without any problem. Audio files involved include ALAC, AAC, AAC iTunes purchases, MP3 and AIFF (including, recently, high-resolution AIFF -- up to 96kHz/24bit). Airport Express copes with all this flawlessly. Later this year I plan to get rid of my old iMac and my trusty old iBook, replacing them with the soon-to-be-announced new MacBook complete with 802.11n. I will upgrade to the latest AE at that stage so as to be completely 802.11n. Jim MacCormaic Dublin, Ireland
