The principle of the ground box is to form a potential difference through tourmaline white crystal, and use the pure silver wire to lead the static electricity and radio frequency interference in the system to the ground box for consumption, making the system more pure. The background will be quieter, the subtleties will be more prominent, and the soundstage will be deeper. But it doesn't change the tone of the system, it's just icing on the cake.
Thanks for your looking .
