You wanna talk depth? ....look at this screwy positioning, it’s got the real amphitheater depth!

Just a temporary thing till I get my cabinetry done for the entertainment center.

Seems to be a different definition of the terms "close-minded" and "open-minded" .........

Would you share your data, results? As you know, I don't care much about debates.

No, that is a misunderstanding. The threshold is usually defined as the point where 50% of the responses (to the experimental task) are correct.
A series of tests is considered to be a probabilistic experiment; humans aren´t machines, variables aren´t constant over time and so on.
So a series of tests will give results distributed around the real (assumed to be fixed but unknow) value of the 50% of correct responses level. The average is a good estimator (converging to the real value) for the mean.

I´ll try to come back with some further explanations tomorrow or the day after.

Again, been there did that. The problem is, some others with a bee up their bonnett will perform the tests badly using poor test methodology without understanding so as to try and prove themselves right. Pretty much what you did.
I have no desire to spoon feed you, as you won't learn that way.
Most important here is critical thinking skills.
Edit: and that is not meant as an insult, most people when forced out of their comfort zone w/r to knowledge, tent to stumble a bit.

It seems most here aren't aware of that? So, as someone said earlier, what's really going on here?

You can do sub-sample shift via FIR. http://home.agh.edu.pl/~turcza/sr/Sp...it%20Delay.pdf

Folks, it would be great if you could find a way back to a less hostile/agressive style of communication.

The entire audio chain is comprised of some very complicated stuff. Electronics which many here are excellent at, speakers...same deal, sources, testing, etc.

But there is a disconnect. A virtual soundstage requires more than just low distortion electronics. It is important to understand what compromises the virtual image.
Without understanding what is needed how does one control it?
Over the years I've tested the stability of both lateralization as well as localization on myself only. And in that process I've had to do a lot of research.

We have quite a few here that are very knowledgeable in human hearing capabilities, it is important that all discuss.
