First off, has anyone tried making their own? Using ground wire and connectors? is there something special about their ground wire?
Or where is the best place to find them. I just got a good deal on a used GC3 with 3 cables. I want diff/more of them.
The CAD website has a lot of info about their ground wires. At first glance it looks like solid pure copper with good quality ends. Whether these are the best is unknown to me. I have only used CAD’s.
The Xangsane site has silver ground wires with banana ends and standard spade and RCA connectors. These are considerably less expensive than CAD’s.
Donald might shed some light on the Chinese knockoffs. I think he has them.
Yes, I have been using Xangsane brand silver cables with Xangsane grounding boxes, but not with CAD. These grounding devices (I use four) make noticeable improvement in the streaming chain.
When I used Puritan Routemaster and Grandmaster grounding devices, I heard a slight improvement in smoothness and quietness when I replaced the green cables with Xangsane’s. But it was nothing dramatic. I do not know if more expensive grounding cables will make more improvement or not.
Not to change the subject but had the mother ship landed? (Diablo 333)
So do they all use the same connectors? So I can buy the Xangsane cables and use in the CAD?
I believe so, they fit in Puritan devices just fine. CAD apparently use the same banana end too.
Paul, UPS here usually arrives at late afternoon. But it is on their delivery truck so it will be here today. I shut down entire system 30 minutes ago. I even have a bottle of champagne ready for dinner tonight🥂
I’m excited for you @dchang05 and @brian.fitterman for the new to u Cad.

I have several GC1 and tried Russ Andrews ground wires with them for a while. I find them easier to manage behind the rack.
After a few months I went back to original CAD wires, that are stiffer and pretty flexible but ugly in my opinion, because of the shape they look once connected.
The CAD wires seem to be more effective to my ears. I mean, don’t expect audible differences but I’m pretty sure they bring more quietness and blacker background on the table. You can hear that when your remove them more than when added to the system.
If you go for the GC3 read the manual, do not connect chassis and signal ground at the same time. I prefer a single CAD for each component, easy peazy!
Thanks for that input. Scott of CAD claims best results with his wires but I never tested that.
Do you have the GC1.1 solely on sources?
I’m going to try them on the mono amps just to see what happens. I tried it on the PowerZone and didn’t notice a change.
Yes Greg, I have them connected only to sources, no amps or regens/conditioners. As you say, I guess a GC1 is ineffective for bigger components like amps. Maybe a GC3 or the bigger one, can’t say.
I bought all my cables from CAD. I think the most expensive one was $325. That seems cheap enough.
I hate to ask this but do grounding cables have a sound?
In my experience with CG 1.1 it’s not a sound but a blacker background and a lack of noise.
Huh?
With the cad you asked how do grounding cables have a sound and I answered something completely different so disregard and I apologize. I hope you get a proper answer. 
No need to apologize Paul! We use grounding systems to achieve blacker backgrounds/lower noise floor exactly as you said.
That lower noise floor gives better resolution of low level, inner detail, hence better sound.
I guess somehow grounding cables could possibly improve the efficiency of the grounding system.
