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 ?
