really? .89c ground lifters?

if i understand correctly (and I'm guessing that I don't), only one component in a given system should be grounded.

so does that mean that all you guys with your GNP-level systems, plumbed with bazillion dollar power cords, are using a bucketful of home depot-style ground lifters? I'm having a hard time wrapping my head around that. Is there some source for solid-gold cryo'd ground lifters I have not found?

How is this problem addressed? My searching skills are failing this morning...there was a lot of chilean and argentinean wine involved last night. thanks.

I have never had to lift a ground. Long ago, in an amp i put a switch to cut it when just fooling around, but it did not matter anyway.
The only ground that has mattered is the ground wire from a turntable.
I just have never had a ground loop. And I run interconnects all around back and forth... just no problem.

I use a piece of teflon plumbing tape to cover the ground of the IEC male inlet on the back of each component. Simple, effective, and no additional connections are needed. You can also use a piece of electrical tape.

Lifting the ground may lower the noise floor in some components. I also use a specialized external grounding unit that is a noise sink.

I really like the title of your thread! Very Glen Beck-esque! Really!

All the PS Audio power cords have a removable ground pin for this very reason. They seem to be well thought out plugs.

In previous incarnations of my system, it worked well to have just the preamp with a 3-prong plug, and the other components (phono stage, power amp) on a 2-prong plug. Putting a 3-pong plug on my old power amp yielded a loud BUZZZ. However, my new monoblock amps (maybe due to their balanced input stage) and phono stage are both doing just fine with 3-prong plugs as well.

Jea48,
Could you explain "JMHO if you are going to lift the ground do it on all the three wire cord and plug audio equipment."?
I didn't quite get it.
Thanks
