In the brief trials I did, the files ripped by db sounded much better than those ripped by EAC. Don't know or care why - the imaging/soundstaging of the db files was just better. Doesn't cost much to try! (BTW, I was trying this w/ WAV files only)
So I try db first, but for discs that don't rip well w/ db, I bring in w/ EAC.
