I use a PC with AppleTv and Airport Express at home, Im going to demo some amps & DAC's tomorrow and have Borrowed a MacBook pro to use as a source with iTunes and some of my lossless audio on it.
Is the Optical out from the Headphone/Optical Jack on the MacBook bit Perfect was going to Hook up my AE but if the output from the mac is as good I can simplify things a lot.
