Audiophiles should tell Beck to shove it. 
Beck can do what he wants. Morning Phase has a very dense atmospheric soundscape, not the kind of sound that lends itself to dynamic extremes. This is folk music for the EDM crowd, not large scale symphonic music or big, punchy rock & roll. The limited dynamic range is an intentional part of the production.
It's a highly processed recording, but I find the sound of the album fascinating. His voice is multiplied and chorused at various intervals with long, sustained reverb trails spread across the sound stage. Even when singing intimately and directly, his voice is tightly doubled.
