Grounding boxes?

My own personal feelings of how these things may [or may not] work, and thus how in theory; could possibly have an affect on Audio systems, has changed somewhat since I first started researching them, well,,, I say researching, what I mean is, looking into them, and my current theory is this;
They are an Antenna, and like all Antenna’s they are tuned to receive/pick up paticular bands of frequencies, and since these devices are usually connected to the 0V of one’s system, where depending on how well the system as a whole is connected to each other, there can for arguments sake be spurious high frequencies present, thus the Antenna, and the frequencies it is tuned to react to and receive, may or may not be out of phase with the frequencies floating around the 0v of the system, and thus may or may not have a crude kind of cancelation affect at certain frequencies.
Just my ramblings!

kinda my take too..noise cancellation on occasion, and maybe sometimes making it worse or no effect

Going back to the antenna thoughts, if you like, you can just use a cable with an rca or xlr connector on one end and the leave the other end open or terminated with a 50Ohm resistor. To which you can cut down to a particular length, just like the ham radio guys do to perform a VSWR test to achieve the closest most desirable standing wave ratio of one for a given frequency. That would would help you with your thoughts of that one Anthony and can done for very little outlay plus zero vampire poo involvement. May take a little time to achieve the desired results but a cost effective way of trying out a theroy.

You could even use a CB vswr meter and some N type connectors however it may prove useful.

Maybe we should all go back to the days where all your hi-fi was in one nicely presented[ or not, depending on taste ] piece of furniture, where all the individual parts ie; Turntable,Tuner, and tape, whether 8 track or the new fangled Casette, were all on the same short ground or 0V, where there was lesser chance of these harmful frequencies [brought about by the use of seperates, joined together by fancy interconnects, and mains leads, cobbling everything together all at an average of 1mtr apart] to impede on our listening enjoyment of the latest trending artist of the day, yes, lets bring back,,,the Radiogram/Stereogram!

Why not indeed I remember the Bush stereo music center, radio, cassette and LP's spoilt for choice we were in them days

Plus zero vampire poo to boot

Right, except the "cancellation" part is just something audiophiles tell themselves to make themselves feel better. The increase in noise is easily measurable.

Here's a tid-bit, there's a company that makes RF generators you can place around the room. They say the "cancellation" bit but in real time we can barely do cancellation in a small amount of octaves for the audio band, just enough to make a pair of headphones slightly quieter to the outside world. What we can't do is real time RF phase cancellation - not even close. If we could we wouldn't use jammers as we know them today, they'd be totally different. You would be able to emit small cancellation waves of other WiFi networks so your signal would be better... none of this is possible with our tech today.

This is classic assumption that better sound = better measurements and it just isn't the subjective reality we all live in. But if you talk to someone not in the audio field they'll assume when you say something sounds better that it measures better... they just don't know.

MIilitary RF Interference Cancellation has been going on for some time

It isn't phase cancellation that leaves anything clean behind. Not even close. The frequencies are too small to be able to do that.

Be interesting to hear a bit more of your take on it Jeremy
