Bluetooth or WiFi - Computer to Stereo

[garyleif]

I found a couple of posts about this question, but I didn't really see the answer I'm looking for...

I'm wanting the ability to transfer music from my MacBook Pro to my stereo, without any wires.

I see there are systems out there where you plug into the computer and it transmits to the stereo.

But what I want to have this without plugging anything into my computer. So using Bluetooth or Wifi or ? I want to transmit to the unit (plugged into the Stereo) straight from the computer. I see headphones that essentially do the same thing, except I don't want headphones, I just want a plugin that I could plug into the stereo?

Any help would be appreciated...
