Wireless to my audio system ?


I would like to try using my Mac and streaming it to my audio system for music stations broadcasting on line. I have not looked into stream rates nor how this stuff gets from one place to another, verses sound. My question being... What products are out there, that DOES NOT cost an arm and a leg to get started to see if I even want to go this route. Currently I am using AR pre-amp and Krell amp. Thank you for any suggestions you folks may have.

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 ?
Yep, Apple Airport express plugged into an AC outlet near your audio system will do the trick. You can go analog out of the AAE or you can go digital out of the AAE using mini-toslink cable and connect to a DAC in your system.
From what I am understanding thus far, the word DAC keeps popping up. I have Air Port on my IMac, but from their just a Rega CD player, pre-amp and my amp.I would think that their has to be something from the Air Port comm. to my pre amp with RCA jacks. Which must be the DAC that is mentioned.. Correct?
