Grounding

cold water pipe in the place i live is plastic and so sewage. one way is to drop ground inside sewage such as drop it in toilet tub, but be careful not to do ya thing when there's thunder or you can loose ya things...
sewage and waste is much better conductor vs. water.

First, I'm not sure what it is that you are referring to that you want to connect to an external earth ground point. Are you talking about grounding the chassis of the equipment, which would normally be grounded anyway via the AC safety ground pin of the power plugs (assuming they are 3-prong plugs)? Or are you talking about connecting the signal grounds/circuit grounds of the system to earth ground?

In either case, though, I agree with Ralph/Atmasphere that if your equipment is properly designed you are unlikely to be accomplishing anything constructive by adding extraneous ground connections. In addition, you would probably be introducing a code violation, and possibly serious safety hazards as well. See the upper part of page 8 of this paper.

What? PLEASE nobody do any of this! Not sure if this is
for real, but don't do it...

What Ralph and Al said is correct.

Specifically i am using a Denon 395 with a Ground terminal on the rear panel. I am not referring to a power cord.

What i may do is get a 10 Gal dirt filled pot and sink the wire right into it on a tent stake or something.

Thanks for replies....R

The ground terminal on the back of the Denon DRA395 is for a turntable, not a chassis ground. You shouldn't need to ground the unit itself?
