I recently purchased an AirPort Express base station to take advantage of the AirTunes Wireless Music Streaming feature. Sound quality is essential, I have ripped my entire iTunes library as AIFF 1411kbps, and I was under the impression that AirTunes / AirPort Express could stream full lossless audio. I have it all setup and working, but I'm not convinced I'm getting full lossless audio. When streaming a track, I check the output speed on the iStat widget and it varies between 116kbps and 152kbps, which I assume indicates that the streaming quality I'm getting is equivalent to a 128kbps MP3/AAC track, far far away from the 1411kbps I was expecting. Is this normal or is there something amiss here? An A/B test between the Mac's 3.5mm LineOut and AirPort Express's LineOut corroborates the above, with the later sounding slightly more smeared / less focused than the former.
