I've know a number of people who have implemented this grounding scheme with great results and at a significantly less cost than Tripoint charges for their technology.
Finally had some time to read post 28 in that thread.
I'm afraid Danmyers has some common misconceptions about "ground."
Namely the misconception that "earth ground," i.e. a rod stuck in the ground, has some particular relevance to an audio system.
It doesn't.
Many people believe that earth ground is some magical one-way drain for noise and RF.
It isn't.
He recommends using a number of copper braid ground straps tied to your components and then brought to a single point that's plugged into the safety ground socket on your wall outlets.
This won't help in any way with regard to EMI and RFI.
Now, what it CAN do is help reduce noise from the single most common source of noise in audio systems, and that's interchassis leakage currents in the safety ground lead of the power cables.
Long story short it's due to capacitive coupling between the AC cord's hot lead and the safety ground lead.
The safety ground is connected directly to the equipment chassis and in many components, the signal reference ground is also tied to the chassis.
Leakage current flows through the safety ground leads and because those leads have a non-zero resistance, there will be a voltage drop across them. This voltage can then appear at the inputs of interconnected components.
By using the copper braid to connect the equipment chassis to the safety ground socket (and it's only about that connection, not any connection to earth ground), you're creating a lower resistance path for interchassis leakage currents and subsequently a lower voltage drop.
However while it can be effective, it's really nothing but a band-aid.
The real culprit is the safety ground.
And it's only required on equipment chassis that don't meet Class II (double insulated) standards.
The manufacturers of low- and mid-fi gear have been designing their chassis to meet Class II specs for decades, and is why you see none of it come with three prong cords.
However the so-called "high-end" manufacturers have yet to figure this out and three prong cords are ubiquitous, even on equipment which may well meet Class II specs. So instead they foist three prong plugs on everyone along with the problems they can bring about.
Sadly, if a high-end manufacturer did come out with a product that didn't have a three prong cord, many would perceive it as some sort of inferior product.
