Trust me when I tell you that V0 kept more of the music intact than 320 did, I can show proof if you want it.
If possible I would like to know why, thanks
The 320 had a hard cutoff at 20kHz, with a totally empty spectrum above it, it threw away completely all frequency information above this point. The V0 kept some of this this information, due to the use of a bit-reservoir. It saved bits on partially silent pieces of the music, so it didn't need to throw away that last 2 kHz of bits.
