It's almost as if these were a high-tech version of putting your gear in a timeout for bad behaviour.
It’s like a luxury “I’m not going to actually do anything but make you think I am” device. If only grounding boxes came with a magic wand and a tutu, then maybe buyers could do a little dance and actually make the sound quality magically improve, whilst their bank account shrinks.
They work wonders for imagination. Suddenly, every small improvement heard becomes the product of the grounding box and not just a figment of audiophool dreams.
