Yes indeed , too little cotton and that sound is noticeable, in the times I have under wicked , I can definitely hear that sound and instantly know. I figure though, that even when wicked perfectly, it's there, but very faint . I have been listening to this for a couple years, and when my wicks have that ever so faint hiss for a split second after, they seem to perform better then if they absolutely don't hiss at all, which happens with slightly more wicking material. I'm a freak, I know.
