    I'd bet carbon and piezo minerals are in the box like the others.

    These high priced grounding boxes are ridiculous, I need to make my own and sell them for reasonable prices like my cables. And they will have proper ground cables.
    Agree. DO IT!

    I'm glad that you have has good luck with potentially poorly designed equipment.
    But I still wouldn't connect an insulated RCA jack to an AC power Safety Ground.
    The check for poor designs is the John Windt 'Hummer Tester'.

    Maybe once I get the speaker done!

    I also have amp and preamp designs, I need to make clones of myself...

    Try an SR Ground Block. Much less expensive than Entreq and it was very effective in my system.

    Here's a 2nd review of the Gutwire grounding cables - the reviewer has used the SR Ground Block:

    Having read this thread with a somewhat open minded, what do all these boxes themsleves connect to. What type electical delivery system to the propery is used can make a big difference.
    All earth (technical earth) is to the ground we walk on, but have you had the impedance from your property to you suppliers earth point tested, this can depend on what system your wired to, if like some in the UK use the TT system it becomes dependant upon where your earth rod is positioned and the dryness of it's surroundings, then if on the PMT system, then every trid property on the phase your on injects their mush from computers, line adapters for baby monitors etc.
    So we need to look for the noise coming into our propery from others and isolate this, thus a balanced mains transformer along with dedicated earth rods within your garden well soaked regualy then listen and hear the difference.

    'technical earth' often comes with a very technical specific definition.
    However the connection to Planet Earth, the ground we walk on is only there for safety during high voltage emergencies and to keep the Neutral's potential near Planet Earth's.
    The earth rod connection has nothing to do with day-to-day AC power quality.
    Planet Earth does not act as a sink or sump for bad electricity.
