I am using Recordnow Max to extract songs from my CDs. Does anyone know what "type" is best? WAV / MP3 (96 kbps) / MP3 (128 kbps) etc. I have tried all of them and they sound the same to me, except the WAV and 320 kbps create a much larger file. Is the sound supposed to be better on the larger file?? or is it just a waste of disc space?? anyone know for sure?? Thanks.
