15 Tracks Ripped Accurately
Further, I was able to bit compare (with foobar) the extracted htoa from the pioneer with the extraction from the matshita in my previous post above and they were bit identical.
So it appears that perhaps my htoa test disc may not have burned correctly, but both the pioneer and matshita extract bit identical data when ripped with dbpoweramp r13.
I tested with the following discs:
queens of the stone age - songs for the deaf
songs in the key of x - various xfiles compilation
blind melon - soup
All 3 were bit identical between 2 drives using r13.
I also tested with sister machine gun - burn, but the disc is apparently slightly scratched enough where I can't get bit accurate extractions.
