iTunes Shared Library question

[Joony]

I'm curious as to if music played over the network is of lower quality? ie compressed further by the computer sharing the music before streaming it out. I did some googling without any luck.

But I do remember something about the Airport Express doing that?

It is played at the same quality as the source material on the computer you are connected too.

How do you know this for sure?
