answer:There are a couple factors at play here. The burn speed would be a factor here, but usually the bigger factor is what quality the CD was ripped at. Generally you find mp3 or AAC files. Both of these are lossy file types (you lose quality when ripping like this) If you do go with either of these file types you want a bit rate of 256kbit/s or above for MP3s and 192 kbit/s or above for AACs. Ideally though you would want a lossless format like FLAC. sorry I couldnt answer this better, I dont know a whole lot about audio quality with ripping. I generally do get files in mp3 but always go for 320kbit/s or above and never really have any loss of quality issues.
