Thanks for that link.
If you've got lossless content in iTunes, you'll get lossless content at the Airport Express.
So, as I understand it, with my current set-up of having the Airport Express connected to the pre-amp with RCA cables, the digital to analog conversion is happening in the AE? Does this affect the lossless data file or does the AE send lossless data over the RCA cables also?
If I connect the AE to the pre-amp with an optical cable, then the conversion will be done by the DAC in the pre-amp, correct? I assume that would be a better option?
