Just in case folks haven't seen it, here is my home-made signal grounding system:

It's wires are connected at the component end to the negative (-) leg of the RCA plug. This plug goes on an unused RCA jack on my pre or DAC (could also be phono stage). The other end is connected to a copper split bolt, and the nut is tightened down on the wires. The bolt just hangs in the air over the edge of my audio rack.



It took all of seconds to hear the improvement: this grounding "embodiment" seem to makes music sound notably more...natural, lifelike, and involving. There's also increase in "perceived loudness".

Cost? About $6.

I call it "Usain".

I have been testing various groundings using Triton's CGS/SGS posts (eg, DAC, amp, clock, network devices(switch hub, router)). What I found during these experiments is ... as more and more components and devices are connected to CGS posts, it is true noise flooer is lowered and stage is widen with more resolutions. But, at the same time, I found that the sound lost dynamic and became flat. I mean...it feels like losing high and bass. or it sounds like all the sounds converge to the middle. (sorry for my poor English.. it is not my mother language)

Is there anyone experience the same thing?

* I used OCC copper and silver wires
* Connections
- Components' RCA terminals (analog and digital) to CGS
- Network devices' chassis to CGS
- Network devices' dc plugs to CGS (like ifi groundhog)
* Multiple connection wires are connected one CGS post
(Around 10~12 wires are connected to 4 CGS posts)
* I use CGS posts of Triton v3 and Alpha a12
(I wanted to separate power distributors between audio components and digital devices)

Thank you.
Could it be the cables you are using for ground? Shunyata offers the Venom, Delta, Alpha and Sigma grounding cables so I would believe they make a difference at every echelon. Also, Synergistic Research also offers different grade of grounding cables for better performance.

Stephen, do you think in your experience an amplifier with no ground pin can be grounded by this method? My amplifier is a Yamaha CA-1000 (1974) with an upgrade IEC socket but in those days they were using cord lamps as power cable, and, no ground. By still some companies do not use ground on some device. Cambridge Audio, Rotel, Yamaha comes to mind. I don't know if by grounding such devices would cause other problems.

If your modded Yamaha with the new IEC socket actually connects to chassis ground and is plugged into a grounded power distributor, then you should be fine.

If not, then you can connect via a chassis screw to a system like the Shunyata Chassis Ground System ground posts.

The method shown above is for Signal Grounding, not Chassis Grounding.

Do you think this is a better way of signal grounding (copper bolt), than connecting to the ground post on the conditioner??

Yes. Because the ground post on the power conditioner is for chassis grounding. This is for signal grounding. They are different things.

I'm sorry... I'm not sure that I understand... Does it mean that by just hanging the bolt in the air, the noise is just dissipated in the air?
and.. according to your picture, it seems to be ok to connect multiple ground wires to the one bolt. Am I right?
