Hello everyone.
As some of you know, I signed up for making some measurements of the Entreq "signal grounding" box. If you don't know what that means, you are not alone
. It is a type of device where you connect it to the ground or negative terminal of your audio signals and it is supposed to improve the fidelity of the system.
I was given a loan an Entreq Olympus Minimus for this testing by the company founder, "PO."
The box arrived a few weeks ago but have been too busy to test it until now. From the outside, it is a nicely made wooden box with a single terminal out back:
The box is very heavy so clearly filled with something substantial. I was not allowed to open the box so my evaluation is limited to measuring it.
I had thought of measuring a lot of things but once I got to it, the reality set in. The box has only one wire going to it, not two. That is, there is no return path for any electrical signal. Think of trying to test a battery with a light bulb but being allowed to only connect one terminal! Obviously nothing will happen whether the battery is good or bad. Same here.
So right there, we are in a very small domain of electrical circuits. Namely, an antenna. That is the only construct I can think of where a single wire is connected to a piece of electronics.
I went ahead and made some measurements. The purpose of the thread is to get feedback on ideas/feedback from folks on it as I like to give it a fair trial. Once we feel good about the data, I will then post it on WBF where folks are waiting for the information.
