Check your signal chain. If there are major differences between the 'lossless' formats, maybe there is another player here. ??
My brief experiments with FLAC, before going to Apple Lossless showed no differences. The reason I ended up with the Apple system is that I went with a MAC, junking out the Windows machine. My player before was WinAmp, which features native FLAC support. With the IMac, the intent is to use the wireless feature with an Airport Express, using the optical out to an external DA, in the form of my CA 840c. An eventual goal would be the IpodTouch as remote.
