Yes, something like this. This all common sense.  Make the main grounding bus with some kind of ugly, very low Ga (1-6) wire with no isolation. Make sure it is copper, so main grounding bus should be a LOT of copper. It should be connected to amp’s chassis in one location, the RCA for the amp input would be the best. If you have think enough main grounding bus then the locations where you connect to it different devises will be less relevant. Ideally you would like to connect all devises to the input ground, in a single point. It is not practical however. A good thick main bus terminal will make it more convenient. I am not a reference in circuits assembling but using the techniques above I never had any ground loop problems in the circuit
 
The connection to the main’s ground is a tricky question. It should be connected of cause, not the last reason is the electrical code demands and the considerations of safety. The really is very different and would be contingent upon many factors: quality of your main grounding, the type and the grounding topology of electrical proxy devises you use, specifics of your particular intentions and many others. So, wire the main’s ground to the amps and it is highly like that you will eventify lift it by using a cheating plug. I did it with each single playback system I had.
