So you mean I can reduce the music file from 128kbs WMA/MP3 to 64kbs WMA/MP3 and I still wont hear much difference. I am a little confused. Would you please explain this to me in a bit detail please. What you mean by MP3pro, I had never heard that before, only heard of mp3. And did you mean that VBR will be more suitable for me? By the way, I am using the dBpower AMP Music Converter right now. Please explain this to me in detail. Your help is appreciated. Thank You,
