Recently, I acquired an Apple TV to serve music wirelessly to the ps audio dl 3 dac. When it works, I have no issues. Even the delay/lag problem I was having just stopped occurring after I restarted the macbook air. Perhaps there was a buffer issue. I didn't need to buy and 3rd party software. It works on any kind of audio/video file. However, every time I try to select the Apple TV in sound settings on my MBA, it kills the wireless router. The only way to fix it is to power cycle the router
