Project ground for billionaire audiophile.
The Earth's core is thought to be iron. Iron is a pretty good conductor.
All that is necessary to reach it is a ground rod about 3000 miles long (and a big hammer). This will be an excellent ground but will probably melt because of the high temperature down there. So you will have to keep on hammering.
Perhaps more practical...
1. In another topic I suggested a separate earth for audio system circuits to remove earth loops with other circuits powering noisy equipment
2. If ground is dry around your ground rod, water it every few days or install a drip feed.
