Wireless to my audio system ?

Another common way to do it is to stream to an Apple Airport Express then connect the mini-Toslink digital output from the AE to the optical input of an external DAC. Even a used 802.11g previous-generation AE is plenty fast enough and can easily be found on ebay or craigslist for under $50 if you're interested in keeping the experiment inexpensive.

Of course you need to have a DAC or a player of some kind with optical input, which can cost anywhere from $50 to many thousands of dollars.

As suggested, an uncomplicated approach is the Squeezebox Touch.

A very simple way is the use an Air Port (AE) express and itunes as Sfar recommends but you can connect it directly to one of the inputs on your pre-amp and use the DAC in the AE. The DAC of course isn't the best on the AE but does a pretty decent job for what it is. You can then evaluate if you want to go further expense wise. I currently stream Radio Swiss Classic using an AE to my stereo system and it works great.

Many thanks to you folks.. regards, Dave

I use a Mac Mini connecting to an Apple Airport Extreme (you use about any wireless router). Then I have a Thecus NAS wired to the router. I store my music on the Thecus and have ITunes pull the tunes wirelessly from the Thecus. This is a little pricey.

If your Mac has means to connect to your preamp, amp or dac,and has wireless capabilities, you can use just that and connect a wireless router to your cable modem.\
Does that make sense to you ?

Nixeus media player is superior to SBT.
