In a nutshell, WAVs are the same thing when they are at 16-bit 44.1Khz stereo. I think CDA is closer to AIF than WAV, because that's what I automatically get when I drag files off of a CD on my Mac (no conversion/transcoding is taking place to the audio). Anyway, rip your files as WAV and there you go. Same damn sound with no difference from the original CD. I can't believe you haven't figured this out.
