As Kal points out, it will go to 24/96 via wireless, but NOT via iTunes. You will need to put your hi-rez music in a separate folder. In the Squeezeserver "Settings" window, choose the iTunes tab and check "use iTunes". Doing this will cause Squeezeserver to catalogue your entire iTunes library. Then go to the "basic settings" tab and go to the line that defines "music folder" - here is where you will tell Squeezeserver that other folder with your hi-rez music. It can deal with both iTunes and one additional folder in this way. I'm just assuming because you are on a Mac that you are actually using iTunes. If not, obviously you only have to deal with indicating where your music folder is.

Will a squeezebox touch play hig rez files sent through wireless router? I'm using a mac with the latest operatings system.
