That is a valid point. A good preamp for anything you record acoustically would probably be of more benefit, sound-wise, than converters. I am hard pressed to hear a difference between my two modern tascam units, unless I really listen and even then, there is a lot of confirmation bias. Once you reach a certain level of sonic competence, that last 5-10% is slicing pretty thin bread. Still, unless I'm recording more than 2 instruments, I always use the 7000. ;-)
