I usually name the Mixing and Mastering the SOUND ( of an album).
I'm a bit of audio enthusiastic listener, and this is not record I would pick up to play someone as really good sound.
Ok, it's fine, all instruments are quite good balanced, bass more audible, BUT... it sounds flat, sometimes a bit muddy and misses the aspect of full, reach sound. And drums. ...hm, very weakly recorded, they have no 'body', sometimes no presentation, no spark.
I better don't compare it with sound of previous DT albums, I pick one sound of progressive metal album that etched to my memory as great:
DOMINICI: O3 Trilogy pt 2
