Could the issue have anything to do with her not being in studio? I am sure the CNet engineers have her set up with a decent mic, at the very least...
I'm not even going to comment on the whole Molle thing(Bring her back!).
But please. Could you get Natalie a proper microphone? Her voice is fairly loud, which makes for quite unpleasent listening when she seemingly isn't using more than a normal desktop microphone.
Tom and Jason are chrisp as hell, and doesn't make me have to turn down the volume. But when Natalie then speaks, I have to turn it down, due to the high pitch.
