This worked a treat & allowed me to route the output of SRS iWow to my hifi via Airport. I'm now enjoying much-enhanced audio, and my sound system was no slouch to being with. Yes, there is a delay, but it's not a problem if you're simply looking to play music. There's some nice touches to the UI: automatically connect to a given target; hijack system audio (who needs HiJack? :-); link to system volume so you can control volume via routed apps or system controls. A well thought out app, well worth it if you want to patch in any audio enhancers to get the most out of your MP3/iTunes/etc. collection.
