I experienced quite bad audio drop-outs when I first connected up the AE to DAC to Amp and played iTunes wirelessly, I tried all the suggestions on this forum, on the Apple Support Forum... soft AE reset, hard reset to factory default on the AE, different setup methods, reinstalling all Apple Airport Utility software, turning off Windows Wireless Zero Configurator, manually setting IP addresses, giving password to the speakers in iTunes, choose both computer speakers and stereo speakers... everything. Still had drop-outs......
Then I found the answer staring me right in the face in the guise of the wireless network activities icon on my laptop. I used to run a wireless G network here and I checked and noticed the drop-outs occurred when the wireless signal strength and transfer speed dropped. So I upgraded to wireless N setup and kept everything else the same, VIOLA! No more audio drop-outs!! Happy man now, but wondered why no one advised checking signal strength on the Apple Support Forum, it is obvious now with hindsight!
Hope this helps others as I previously spent HOURS trying to get rid of drop-outs without success.
