vibrato

Am I the only one in the world who thinks vibrato can "hide" the voice? I mean, I like it...but I think I like it in moderation. If there is too much of it, I think it can really hide that true quality the voice possesses. If there is only a little, even no vibrato, I think it focuses on the quality. Sure there's the immature sound that comes with no vibrato, but I think a voice can certainly sound mature without vibrato as well. I listen to recordings of straight tone pieces of choral music, and I can tell that adults are singing. I can tell when solid children are singing as well. I may be wrong, but I still think that vibrato can cover up someone's true voice...something to be studied, I guess.
