Connecting the ground wire makes music less lively


Friends,
Lately for some strange reason I heard hum from my TT setup. When I connected the tonearm ground wire to the phono the hum was gone. Thats the good news. The bad news is, when I heard the music with the ground wire connected, it sounded less lively, less palpable. Some vitality was taken away. When I remove the ground wire the life in the music is again back, just that the background hum is audible during silent passages (thats irritating). Has anyone else heard this effect ? Is there a solution to this problem ?

My phono stage is very heavy and can't be moved around. I have to say this problem is quite disturbing because either way there seem to be a serious compromise which is not really the fault of the components.

regarding the ground I would try both either ground the Garrard at the motor bracket and also on the cable or just the motor, or just the cable. You should find out which works better at your system. Also check if there is ground going from the arm....
What exactly does it mean by ground the Garrard motor ? Please advise since I am a total novice at DIY.
do you have 3 wires on the Garrard power cord? Means is there ground wire attached at the motor bracket ? if not try to use separate wire to ground it there...
The Garrard motor has only two wired terminals. But my upgraded pc has 3 wires. The ground wire is just left taped and loose on the motor end. Should I connect this ground wire to some area on the motor ?

Congrats on your Garrard. Phono hum is a nasty. I have been pretty unsuccessful in removing mine. Hope you have better luck. Do share your experience.
