I have two Sony recorders (D50 & M-10). I recently picked up a Zoom H2 as a back up to bring to places I didn't want to bring either Sony. If I'm using external Church Ca-11 cards and battery box will the recording from the Zoom be any less quality then the Sony decks? They are all digital recorders so besides internal mics and some functions is there a difference between decks recording quality? Thanks for any input
