No can do on the wire. It's the slack I need for the sliding keyboard shelf.
However you might appreciate this attempt at decoupling.
The lower piece is probably a 1"x2" African Mahogany frame with the middle filled in with some sort of high density composite rubber that hockey players walk on on the way to the rink. The top is a White Birch cabinet door. The blue stuff is an actual acoustical product. I might dress up that edge but if you're in a position to be looking at those little holes and the blue latex foam ... that stuff is the last thing on your mind.
