Executive summary:The first file pair I tested cancelled perfectly.
Do I need to go on?
Why am I not surprised? ;-)
I don't have experience with devices which don't work.soongsc said:
Only incompetent circuit 'designers' think of ground as a sink. All the rest regard safety ground as part of a circuit which only gets closed under fault conditions, and audio ground as a reference point from which signal potentials are considered. In fact, any talk of ground as a sink is a clear flag to warn us that we can safely ignore almost anything else that person says.
There are lots of bad circuits out there designed by incompetent people; some of them are quite expensive. Adding a wire to a box of dirt will not improve them, however much you paid for it.
All sufficiently linear circuits with sufficiently flat responses and sufficiently low output impedances and sufficiently high RFI rejection (etc.) do sound the same.
IME that statement is true for sighted evaluations, and false for DBTs.
Who is not surprised? ;-)
So what exactly is a sink? According to your definition (no circuit) it doesn't exist. And your neutral is bonded to dirt so ground is always connected to your power system not just in "fault conditions".
1 definition I found.
Current Sinking
When a load is connected to a device so that current flows from the power supply through the load and into the device, then the configuration is said to be current sinking. When current flows into the device, it is said to be sinking current.
An example of current sinking is when a series resistor and LED is connected between power (e.g. +5V) and a microcontroller pin. When the microcontroller pin is switched high (logic 1) then the current to the load is switched off. When the microcontroller switches the pin low (logic 0), current flows through the load.
And since the distribution transformer neutral is bonded to the dirt the dirt can be a return path and will sink or source current. Why is this so hard to understand?

Is this a rhetorical question?cbdb said:
Whose definition? What doesn't exist?
I'm not sure I am following this conversation. What has safety grounding of power systems (requiring two ground connections) got to do with connecting signal ground to an isolated box of dirt?
Just because current 'can' get back to neutral via a ground spike doesn't mean it ever should. It shouldn't. If it does you have a big problem somewhere.
I shouldn't add to the clickbait but just rarely this particular waste of electrons really annoys me.

I agree with you, soongsc. I believe in what I hear, and virtually all electronics sounds different to my ears.
Henry W. Ott wrote this rather technical paper way back in 1983:
Ground- A Path For Current Flow

I'm with you on both points.
One really interesting thing is being able to walk up to any system and change the sound of that system.
Fri night experiment was putting my filters throughout backline and PA/monitors.
The result of this pretty much final experiment was the cleanest, hugest, fattest sound ever, seriously.
Playback of the recording at a party the next night showed how good the live sound really was.
Music systems are about fun.

To almost any direct personal observation, yes. And yet most refuse to believe it. Why?
The curvature of the earth is plainly visible to the naked eye. Its always had me baffled why the spherical earth concept took so long to establish.
The most plausible explanation I can think of is the controlling influence of a third party we are not allowed to mention on this forum: being burnt at the stake is not the most pleasant of ways to end one's existence.

The spherical earth concept has been established in Europe in the 6th century BC.
In the middle ages someone produced a woodcut of the imaginary workings of a flat earth to poke fun at the few who believed Earth to be flat which is now taken as proof that everybody back than believed our planet to be a disc.
