It is almost always advantageous to create a central, common, grounding center. The most logical place to do this is at the power distributor. This is why we provide ground lugs on most of our power distributors.
So yes, connect all power distributors together and use this as a common point to connect other equipment.
Some amplifiers, especially tube amps, do not like to be grounded. They may hum. So it is always best to try each and every component individually when creating a grounding system.
Use large gauge wire or ground braid to make the connections. Twelve gauge wire would be an absolute minimum size to use. If the ground wire lengths are long - over 2 meters - be sure to increase the wire gauge size.
