well I was using sonic stage to backup my cds in hi-sp(the most important ones) then i decided to record Madonna´s American Life through optical on the same md i recorded Ray of light through Simple burner. let´s say there was obvious difference in the sound quality between the two. My question is if both were digitally transfered wouldn´t they have to sound the same in terms of quality? or is simple burner offering a poorer digtal copy on purpose? any Ideas why this happens? I remember once i read someone posting that he found transfers Through usb better than optical I beg to differ cause this is not what i am experiencing. thx for your time.
