Hello, I want the best quality in my music so If you can answer these questions it would be helpful: 1. What has better sound quality at 320 kbs? Variable Bit Rate or Constant Bit Rate? 2. Will my mp3 audio be lossless of it's current data when I convert it from 320 vbr into 320 cbr? 3. Will I have better/restored sound quality if I converted a 128 kbs into a higher number like 320 kbs? 4. Is there anything else I need to know about MP3 sound quality? 5. If I rip an album into .wav and then convert the .wav into mp3 will I lose quality compared to ripping to mp3 straight from the cd?
