Hello, vv.
I do not have this unit, but its smallest brother had been on my short list a couple years ago until I tried out one of PI Audio's UberBUSSes. With this in my system, I knew I had what I wanted. Have you looked into these at all?
Some folks buy an UberBUSS and then plug either a DigiBUSS or one of Dave's smaller BUSSes into an UberBUSS depending on their system's components.
For approximately 1/4 or even 1/5 the investment, a silent, black background is achievable.
