Ungrounded interconnects...help, please

[Suprfly2k]

I have tried, to no avail, to find a source for ungrounded interconnects on the world-wide-internet.

Does anyone know where I can get some or adapters to unground my current interconnects?

Why on earth would you want to un-ground your signal?

Do you mean un-grounded or un-shielded?

You can't un-ground an unbalanced cable. You need TWO conductors. If you just connect the hot leads, all you're going to get is a bunch of [size=x-large]BZZZZZZZZZZZZZZZZZZZZZZZZZZ...[/size]

x2. Makes no sense.

Only if you have balanced headphone cables will there sometimes be no ground. But if you use a shield, you want to ground that to pin 1 of the XLR which should be connected to chassis ground.

Hmmm.

I recently bought a source/input switch. When I introduced it to my system, I got a loud ground hum. By by-passing the ground on my headphone amp's power cord, I could make the hum go away. That is not an ideal solution. The maker of the switch and another member here suggested that I use un-grounded interconnects for the headphone amp. See this thread : http://www.head-fi.org/forums/f5/woo...estion-459042/

I actually should have said "interconnects grounded only on one end". Any idea where I can get this cable, or an adapter that would un-ground one terminal?

Thanks.

I think he means a cable which has the shield connected only to one end. But that's not going to help you out in terms of ground loop issues.

I assume you get no hum when you connect your source directly to the Woo without the switch box?

Also, how many sources do you have connected to the switcher? If it's more than one, what happens if you disconnect all but the one source? Do you still get the same hum?

Tara Labs has unshielded RCA Interconnects. I have a 6 foot set. They sound very warm, or dark actually.

This is yet another misdiagnosed ground loop issue. Get the Humx or an isolation transformer.

Ah, les mots justes.

Someone got it!

Aren't single-ended cables supposed to only have their shield connected on the source end?

DAMN IT! My pun detector was at the cleaners that day.

You mean have their shield connected only on the source end.

And yes, unless of course they're a coaxial design. It's called a "telescoping shield."

I contacted the manufacturer of the head-phone amp, and he said that there would be no problem removing the ground from the power.

If by that he means defeating the power cord's safety ground, that's a very irresponsible recommendation in my opinion.
