Double ground system (Tweaks)

Hello Stephan,

Thanks for the tip, grounding is very important as it can kill the good things in the sound completely if not taken care.

My signal ground is nowhere connected to earth ground except at one point taken from the system (the pre-amp worked best in my system). For the rest all housings and table is connected to earth working as a good RF shield.

Since 2 years I have a new earth with measures resistance of only 7 ohms (if I remember correctly) !

Having such a low resistance makes it sure that all floating current is directed away from the system to that earth (current is lazy and will only take the most easy way - low resistance!)

Mine went about 28m deep through very hard ground (the best for low resistance) which only could be done with a machine...

It did not cost too much either (around 300 Euro including labour) for a clean and safe ground! Normal earth is between 50-100ohms and called safe... :shame:

Cheers,

Bert
