Isolated Ground causes ground hum.

Do I have to remove all the ground rods I already planted is in the ground? Is there any issue if I keep them there? Its kind of hard to remove those rods now.

No problem with leaving them there. I would remove the ground wire from the rods from the inside of the house. Cut it off outside the house or bury it in the ground outside the house.

One major thing I've learned over the years of reading the Audiogon Forums is you never can go wrong following the advice of jea48, gs556 and several others that I have not mentioned. Thank you to all those prefessionals...

"I only connected it to the ground post on my Shindo Aurieges preamp. "

Isn't the purpose of that grounding lug as a place to ground your turntable or phono preamp?  I assume the chassis of the preamp is already grounded.

lak,

Thank you for the kind words.

I put my system back to normal. Thank you for talking me out of the dangerous isolated ground gentlemen.
