dbpoweramp is not suitable for ripping because it doesn't provide error reports or support offset correction

so you can never make an exact audio copy using dbpoweramp, and if there's errors while ripping... you might catch them by ear, because there's no other way with dbpoweramp!

as for ape, I agree. I believe it is like what rar is to zip. only prob with ape is some strangeness with the new version communicating with shntool/tlh.
