Keep in mind that some speakers are designed to actually be more neutral with their grills on. Harbeths are a good example.
That doesn't mean some might not like them better with the grill off. That's somewhat the same effect as tweaking the treble control up a bit (back when most equipment still had tone controls.) The key is to remember you're the only one who needs to be happy with your choices.
