Ripping Techniques for Digital Audio Players

Ok,
I just got a wifi squeezebox and a while back, downloaded EAC (Exact Audio Copy). I have been copying my cd's uncompressed, which results in a .wav file. Is this the most preferred way (for best fidelity), or is Apple lossless even better?

Out of the box the SB is impressive when playing uncompressed files. Any tips on how to improve the sound? I see welborne labs has a nice power supply. Any experience here?
Thanks!
