CD part of this limited edition set has catalogue number of VICL-62472. I assume that's the regular edition catalogue number.
Audio has fair amount of dynamic range, however, it appears to be just the overall range. Individual sound components (any specific instrument or the voice) appear to have very limited dynamic range of maybe just over 12dB. It's a good example of why it's impossible to tell how good something might sound purely by waveform analysis. It's fairly easy to tell if something will sound horrible by looking at waveforms, but the reverse is not necessarily true.
What a shame, because she has a wonderful voice. I know. I heard her live at Anime-Expo 2007.
