I feel the leaness is coming from AC cycles. I checked with a guy I know and he agrees with me.

When using he 1070 to decode movies, the sound of the vocals and dialogue now using the digital coax out is unacceptable. Since i just had my vaunted Denon modified, I can use that now to decode movies and the sound of voices and dialogue is vastly superior now when it used to be inferior before the modification. The 1070 makes the special effects more dynamic.

When using music that I am intimately familair with, I am gettinmg a leaner sound and that has to be the AC causing this.
