Need Help With Building DIY Grounding Cable

I have built 3 ground boxes. 1 each for my speakers with subs built in and one for my system power conditioner. I have them posted on my virtual system. I have noticed an improvement using them.
I connected my main ground box to my power conditioner’s ground lug spade to the ground box with banana. My speakers are connected spade to banana.
You can connect individual components to the box directly as well using one open rca or use one component (Amp) as a component hub connecting all components to the amp then only the amp connects to the ground box. Some use alligator clamps on open rca input but I feel rca connectors stay connected better. I soldered my rca’s to outer ground connection. I have not needed to separate digital and analog. Good luck with it. Fun stuff.

Check out this link very helpful ground box info. I own one of his RF Router for my HT system. Also, search agon thread on ground boxes.

@tksteingraber Thank you for your response. Yes I am going to connect the bnana plug to the shell/-ve of RCA plug leaving the center pin as it is.  I saw the photos and desription of your ground box, it surely looks nice.

Just remember signal ground and chassis ground are not the same. If you components are balanced be very careful. Typically the neg on the RCA or the outer circle is the only thing connected to ground as long as the components are not XLR/ balanced. 

@hsounds my components are not balanced and I am not using any balanced input to attach the ground box, it will be only to the unused unbalnced inputs on DAC and integrated amp. Thanks for the caution.
