Thank you all for your responses and advice.
(1) TBG, Gregadd, and Rex--I respect all of you replies and will investigate/research your ideas.
(2) AvGuyGeorge--I noticed no difference in sonics with the amp connected to the wall outlet vs. monster unit
(3) Darrylhifi--I don't know why some reputable companies make power cords with removable ground pins: It must be that under certain conditions the ground pins are not necessary. I think you have to be careful not to conclude that since they are removable they are not required. I'm too ignornant to know what would be appropriate electrical conditions to remove the ground pins. Will do some research here.
(4) Warnerwh--My toaster has 3 prongs. Maybe I have some "electrical ground phobia issues"?!
Gregadd has a very important point: Respect electricity. I need to understand with 100% certainty that a ground manipulation is safe, and will continue not to use cheater plug until then. Is it worth it to put yourself and family at risk? As an audiophile, I have gone though extraordinary measures to improve sonics for the quest of stereo nirvana--but we all have to be careful and knowledgeable about the electronics.
Respect Electricity.
Thanks again,
Rob
