Love the content, do not like the narrator

Because I have always been a fan of the print mag, I thought listening to the news would be equally enjoyable, but the narrator's monotonal style is irritating and his variations in volume are distracting. I would like to know the name of the narrator so I can avoid him, but I see no listing of narrators for these mags! (why is that?)
