IMHO we must accept all strong opinions about this type of device (not only the Tripoint) without any astonishment. Their designers intentionally keep secret of all the basics and fundamental, not only the technical details, because they want to avoid any dangerous technical debate on them. There is a price to pay by this desire to keep people in the darkness - we all debate with the the same level of knowledge and the same inadequate arguments, but no one is above being debated.
The DIY people and competition spies are just an weak argument. Many designers know from experience that technical debates in free open forums are dangerous for marketing. Some times they enter it and are asked to retire by their distributors ...
I am currently using the Nordost QRT Qkore grounding system. I have listened to its effect in my system, but still do not have the faintest idea why it changes the sound like it does. But in reality it changes it!
