Different cables, different measurements?

[pogo]

I think we have several effects playing in here. Where are your room modes, for example?

yeah, this is why i share 2 videos

It shows the measurement method is wrong.
There is no question you hear differences but the measurements only seem to confirm your suspicions.
10dB narrow band differences cannot possibly come from cables, not even EQ is that narrow band anyway.

- I've done each test multiple times to confirm the results using pink noise (the resoults were exactly the same every time)

Did you test multiple times each cable of A and B in sequence of

1) ABABABABABABABAB
or
2) AAAAAAAABBBBBBBB
?

For example, I see that curtain shows different light slot through the windows in 2 measurements.

Without exaggeration, I repect this kind of curiousity. But really expensive cables for GHz measurement show only 0.? or 0.0?dB variation DUT by DUT. If copper and aluminum could result in 10dB difference in kHz range, I think world could be really chaos.

Ahh! -This is the explanation for why the world is indeed chaotic.

I'm suddenly persuaded....

Oh boy do we solve much grander things than HiFi issues on this forum!

Plus we don't know how accurately the operator is placed in exactly the same position for each measurement. I very much doubt he could get that very precise after moving to change the cables over.

First step is to minimize variables.

Second step is to make only one change at a time.

Third step is to have a "Baseline" that is 100% repeatable.....
