If the preamp's chassis is grounded to the AC ground then you could connect the chassis of the DIO to the chassis of the preamp. Myself, I simply ran a wire from the DIO chassis to the screw on the AC outlet. I noticed a nice improvement, as many have.

I do think this will vary from system to system. In my case, both my integrated and transport had power cords with a lifted ground, so in essence all the chassis in my entire system were floating. By connecting a wire from the chassis of the DIO to the AC outlet I created a ground reference for all the chassis, which created drain for noise. All the components are connected via interconnects, which are connected to the chassis (chassis ground) of each component.

Some have reported the type or size of wire matter when grounding the chassis, as well as where to connect it to the chassis, i.e. a screw, laying loose under the chassis. Give it a try, you might be surprised.
