Got this to stream music from ITunes on Labtop to remote speakers of stereo. Just have to say that set up was easy. Set back was that after it was installed I found out that the connection is skipping since upgrade to ITunes 8. Problem is with ITunes and the company does not provide any support for this issue. With music dropping in and out this set up is not working any longer.

For a bit over $100, I extended my wifi coverage and distributed an audio signal substantially better than any sound card I've ever had (lots).

I've had the AX for a year using wifi. My signal was too weak (distance and walls) and I was getting the inevitable dropouts at times.

I just changed it to a wired WDS approach to provide ethernet to the other side of the house and provide a good quality audio signal to our reference system.

The DAC is solid and provides a much higher quality signal than whatever is in my computer and an M-Audio sound card. The improved wifi coverage was substantially better than with a Hawkings amplified antenna could deliver.

Setup was not the simplest. I first attempted it in "Expert mode" (Airport Utility) and, while everything worked I was getting three different error messages. I then reset my AEBS (worked on a DI-624 as well) and AX back to factory defaults and let Apple's auto configuration tool do the work. Everything worked, no error messages. Then I went back in Expert mode and set some static IP's I need.

For the money, a really product and good execution by Apple.

This is a November update (installed in October): After listening to the Airport Express via the analog out and comparing the same radio station streamed from a Squeezebox, we realized although it is better than our soundcard, it leaves room for improvement. We added an outboard DAC. Although at least doubles the price, the addition of a DAC is highly recommended to those who value sound quality.

The setup directions are almost useless, not unusual for consumer networking devices no matter who makes them. The most important thing to keep in mind is it takes time for the unit to connect to your router, just restarting after being powered off is slow. So don't get impatient.
The instructions included in the review by C.P. Cavafy are very helpful and will get the job done just follow them and allow time for the device to connect.
I use it to connect a Slingbox as well as the Air Tunes feature. It's perfect for both and is easily the most stable wireless access point I've used.

This product is listed by Amazon for over $200 yet the current Apple product is less than $100. It is extremely disappointing that obsolete products such as this are being recommended by Amazon.

Be an informed buyer. Note that M9470LL was first available June 14, 2004!!.

Be sure to get the newest version (Apple part number MB321LL/A) which has 802.11n and NOT this item (Apple part number M9470LL/A) which is 802.11a/b only.
