Problem is, dbPoweramp doesn't let you enter your own commandline for flac or lame.
CDex allowed that, but 1) CDex hasn't been updated in a long time, and probably never will be again, and 2) It likes to crash frequently on my system - error in ntdll.dll. It might not have been an easy method to learn, however, CDex did use an effective way of passing parameters from the CDDB info to the encoder of your choice - FLAC in my case. I just like being able to set customer parameters for the encoders - I don't mind if it takes a long time for each song, so I like to set them to the absolute highest quality that they can manage, while still getting good compression ratios. The drop-down menus just don't give that functionality.
CDex also keeps the original directory structure, negating the need to re-sort all your files.
