I have recently starting to use dBpoweramp to rip a few of my most favorite CDs. I tried ripping one CD about three or four times using ultra secure mode. Each time the rip is not accurate based on a comparision with other rips of this CD in the data base. I have been able to rip other cds using the same drive and set up. So what to do? Does this mean there is some defect on the CD? Need to buy it again?
