really? .89c ground lifters?

On my system the solution is open the IEC Oyaide (equipment end) and lift the ground.

The reason to not do this at the wall is that would leave the ground as potential antenna into the equipment. This method leaves the wall plug ground pin in place which helps secure connection, especially for heavy AC cords.

All that being said, care must be taken when lifting the ground on any piece of equipment as the potential for shock is greatly increased.

it's like being visited upon by the gods when you weigh in, Albert. Seriously, thank you for taking the time. Very much appreciated.

To clarify, you're opening up the IEC connector and dropping the ground there?

And is it generally the amp (or one of them) that's best left grounded?

sorry, I glossed right over IEC in your post.

No definitive advice on what components are best grounded and which best ungrounded. Over the years that answer has changed, dependent on individual components and even RCA versus XLR cable terminations (maddening).

Ground is one of the most misunderstood and difficult issues in high end systems. Get it right and everything sounds better and you obtain that nice black background that everyone wants. Get it wrong and you chase hum and buzz around via various sources.

I've had my share of this in my own system even though I run star grounds and dedicated lines for every piece in my rig.

As for the cheap ground lifters, I find them invaluable for testing, no sense in permanently lifting the ground on a AC plug just to see if that helps. The lifter lets you know where to work and then you can make it permanent.

Thank you but that does not apply to me. I do post a lot but as with most things in life, you get back pretty much what you put in. I can't count the number of time another Audiogon member has posted a comment and I cannot add a word, because it was so perfect.

Soundgasm,

JMHO if you are going to lift the ground do it on all the three wire cord and plug audio equipment.

Make damn sure if multiple dedicated branch circuits are used the circuits are all fed from the same Line, leg, of the electrical panel. Use a volt meter to confirm.....

The object is to not have anything within arms length that is grounded. If a ground fault current path does not exist there cannot be a difference of potential for an electrical shock to happen.

Now of course if the floor is bare concrete or any other conductive surface lifting the ground would not be a good idea.
