I just purchased the dBpoweramp Music Converter. It is a very nice CD ripper with an extensive feature list. The most important feature is the AccurateRip and provides a comparison from your RIP to all the other RIPs in the online database. If everything matches then you have a perfect RIP and can confidently add the files to your digital collection. An added bonus is the availability of cover art which is pretty cool. I have run into a few albums which don’t agree with the online CRC but since I am using the secure rip and the AR score is low I am not concerned.
