Power Cord with removable or no ground

I'm trying to replace the PC on my pre amp however I have one without a ground plug.
The only ones I know that are out there for brands would be the PS audio with the removable ground ($$$) or I contacted Frank at Signal Cable and stated he could lift the ground and do a custom order.
Is there any other manf that make these types of PCs? I honestly haven't see any others and was wondering if anyone has this or just normally uses a cheater plug....
I kinda like the PS audio one as that way if I switch pres I don't have to get a different PC (and not sure how many people would want to buy a aftermarket PC with ground lifted).

I got my PS Audio from ebay which can have them pretty cheap some times. Even their budget most power cord has the removable ground. You could always make your own too and save a bunch of money.

I've seen IEC PC's sold without the ground, search the web a bit. I can't remember the designation for that style of IEC, but they do exist.Source: Bluesound Node 2i - Preamp/DAC: Benchmark DAC2 DX - Amp: Parasound Halo A21 - Speakers: MartinLogan Motion 60XTi - Shop Rig: Yamaha A-S501 Integrated - Shop Spkrs: Elac Debut 2.0 B5.2

Look here: I thinks it's the C18 type....http://www.powerstream.com/IEC-features.htm

Couldn't you use any upgraded power cord and if you needed to lift the ground,just get a 2 buck cheater plug ?HT SYSTEM-

Yeah, I think they both accomplish the same thing.

Cheap cheater plugs degrade the sound and defeat some of the advantages of a higher grade power cord. I don't know of any audio grade cheater plugs.Proud and loyal citizen of the Digital Domain and Solid State Country! -

Would be nice to have a high quality cheater plug that can have a tight grip with gold plated connectors. Or maybe more companies should make the ground pin removable like PS Audio. -

That may or may not be true, and if it is, your back to the old arguement of the wires in the wall not being of higher audio quality either.HT SYSTEM-

Ray, did the stock power cord on your VPI 16.5 have a removable ground pin? Mine comes off. Unless of course it is a manufacturing defect.
Sorry for the derail it's just this sparked a memory cell. -

The quality of wall wiring, and even the power company's wiring all the way to the generating plant, has been addressed many times on the forum.
The water pipes in our homes are not the most hygienic. Municipal water systems are not sterile systems. Some municipal water systems provide "adequate quality" water that has objectionable tastes or odors. Still, this water is certified by the authorities to be of adequate quality suitable for bathing, drinking and cooking.
Why bother with water filters in the home when the water has traveled though miles of un sterile municipal water pipes?
Why bother with getting a clean glass every time you want a drink of water? A dirty glass that has been sitting in the sink or dishwasher for a day or two probably has no more germs than the water coming out of the tap that has traveled through miles of decades old piping, right?
Just as the taste and smell of municipal water can be improved by using water filters and drinking out of clean glasses, the quality of electric power can be improved by using active and passive power filters and by choosing power cables and connectors that shield against environmental noise and which do not significantly add noise of their own.Proud and loyal citizen of the Digital Domain and Solid State Country! -

the stock cord does not have a ground pin and I was adv to use it this way. -

I don't remember. The original power cord is in the 16.5's box in the attic. I'll take a look later today.Proud and loyal citizen of the Digital Domain and Solid State Country! -

Don't bother Ray if it's a hassle thanks for the offer though!:) -
The power cord that came with my 16.5 was just a generic 18 gauge cord with no detachable ground pin.Proud and loyal citizen of the Digital Domain and Solid State Country!

Hmmm! Mine is a very heavy cord I don't know the gauge. I wonder if the ground pin just got pulled out by the outlet? I just pulled it out of the socket and pushed it back in. It had a retaining groove towards the inner end of the pin. -

YUK!
Thanks for the "wake up" on the water.
I like the comparison though it's apples and oranges.
Chris, How about a power conditioner to cure that issue? It's the obvious call here OR did I just miss something reading it for the 5th or 6th time? My tiny little hat holder doesn't function well at times. -

Why do you say the comparison is apples and oranges?Proud and loyal citizen of the Digital Domain and Solid State Country! -
Two different sources. I understand the thinking and I do agree.
I don't think I'm over the "tap water" though. LOL!
I use bottled water for everything except my coffee that I'm drinking now and I'm envisioning the coffee path and all it's "passengers". -
Hey Chris, what was the reason you were told for sticking with a power cord that has no ground?
The stock PC on my BDP-51FD has no ground, however I use a SignalCable Digital Reference PC (that has a ground) and have no issues with it. Just wondering...
Cable on left is the SC PC, PC on the right is stock.

Does the female IEC input on your pre have a ground pin? If not, would it matter whether or not your PC has a ground pin or not at the male end?
My Marantz DV-9500 has a female IEC jack with only the two pins, no ground pin. I've used both a Signal Digital Reference (with ground pin on male end) to no ill effect, and obviously no grounding connection has been made.Jay

well when I bought the unit the told me its recommended to use it without the ground pin with PCs. I once tried using one with a ground pin and it caused a lot of buzzing into the system. The outlet I check and it is properly grounded ect. I removed the cord plugged the old one in and it worked like normal again.
I do have a ground pin on the back of the amp for the IEC socket part. There are 3 pins in the back.
