I think susceptibility to noise by the components and the noise in the environment is the biggest driver of will a ground box work at all.
I get Lee is a Shunyata fanboy. I am a Torus fanboy. Being as such, I highly doubt he would tell someone to stop at 1 if you heard a positive affect. I doubt he would say stop at a entry level cable. I would assume he would follow the official Shunyata speak that says the more the better and the higher quality the ground cable the better. And then you need to plug it into an Everest for the highest effect. That is what all the users I have talked to tell me. They find better cables give a more pronounced affect. They find multiple boxes are better than 1.
Look, Entreq and other are the same. You don't stop with one box. Its a rabbit hole. Similar to how Steve went down the Schnerzinger hole. Its like crack. Accept the first wack ain't free. But once your on, you want more and more.
You can pitch it from any angle. If it didn't work, you need more to make it work. If it did work, you need more as you have issues and really need to repair the system.
Its sort of like, why half Auu it. Right. If your going to do something, do it right. And in the end, you spend about $17,000.
