Comparing rips


I did an experiment and the results are mystifying to me. I ripped the same track with three different programs:

iTunes (error correction on)
dbpoweramp (free version) - AccurateRip verified
Exact Audio Copy - AccurateRip verified

I ripped them all to WAV.

iTunes and EAC returned the same number of bits (there are all "size on disk" numbers):
191,135,744

dbpoweramp returned a slightly larger file:
191,172,608

I then converted them to Apple Lossless files using the encoder in iTunes.

Again, two of the files matched the number of bits, but this time it was EAC and dbpoweramp!:
85,237,760

iTunes returned a different number:
71,892,990

I then ripped the track directly to Apple Lossless from dbpoweramp and dbpoweramp (EAC doesn't do this) and the results were as before:
iTunes: 71,892,990
dbpoweramp: 85,237,760

What is up with this? Has anyone seen these kind of results also?

Thanks for your help.

could it be the track information? The reason I use dbpoweramp is because it works at attaching the library track information for wav... others I have used had problems.
