Noise reduction

It lives! We shall see later, when I can be bothered.

Yep that looks a fair comparison. Go for it.

None whatsoever. But since when did that qualify you to judge sound quality of Hi Fi.

Electronics qualifications and/or experience doesn't qualify anyone to judge sound quality, but it can educate them enough to understand what creates an earth loop, what makes an earth loop create hum, how to shield circuits from RF interference or magnetic fields etc. Understanding is what allows people to make dependable predictions, like "will this create an earth loop?"

It will do exactly the same job!!

Yes. I used an older plug so I could take the + and - pins out in case anybody was concerned. Only the earth can make any contact.

I hope only the earth side of that RCA is soldered to the earth wire. Having the centre pin connected to earth as well may cause problems depending on whether you plug it into an input or an output.

The effects of this device will depend to some extent on how the rest of the system is wired. If it is fully floating, it won't do much. If one component already has 0V connected directly to earth you will create an earth loop. If the two components are plugged into different mains sockets you will create a bigger earth loop.
Well-done on actually soldering something up to do practical tests, but it would be wrong to draw general conclusions from an isolated example.

Yes. Only earth soldered on the phono plug. Although you've made me wonder what results might be on an amp that had shorting plugs fitted.

Of course it will.

Safety is a given in any component - caveat emptor, and any mug can hear an earth loop so we can dismiss that from the equation.

Why are you trying to confuse the real debate about whether this cable can improve sound quality?

Are you saying that this device can't create an earth loop? Or that if it it does, it doesn't invalidate it or its price tag?
I'm not trying to confuse the debate. As far as I'm aware I'm debating what everyone else is debating - with the possible exception of yourself.

BTW, in my experience it's not true that any mug can hear an earth loop. On many occasions people hear a hum and assume its an earth loop. Often it isn't.
And I've heard many systems that hum where the owner is either oblivious to it or assumes that it's a price worth paying for the superior sound quality.

I'm not saying anything, remember I'm not an electronics expert like you. What I am saying is, if you evaluate it in your system and it creates an earth loop then it goes back as unfit for purpose at whatever price it is. It's not rocket science to hear an earth loop within 1 second.

Well please lets have that debate with me about sound quality.

Lets hear your argument for saying it cant improve sound quality given the understanding that it needs to be electrically safe and not create earth loops.

Carry on chaps!
I haven't laughed so much in years
