V-Vocal coloring vocals

When I use V-vocal on a vocal clip, it colors the sound, even on unaltered notes.  In other words, if I change one syllable, the entire clip has a very slight, but noticeable "robotic" or "hollow" sound.  It is especially apparent in breaths and consonants such as F's and S's.
 
Does anybody else notice this?  Is there a setting I may have missed to counter this?
 
(Please, no wiseacres with the "use melodyne" retorts--although I'm seriously considering getting it)
Cheers all!
