It might be logical in your head Jeff but it makes zero sense to me or anyone else that I know.
Here's the thing Jeff. IF you can hear the difference than it CAN be measured!
Even things like separation, dynamics, whatever it is that you feel has changed can be measured.
Any modification that you feel has changed the output of your amp going to the speakers will have made changes to the electrical signals feeding the drivers. I think even YOU have to agree to that. Without changes to the signal feeding the speakers there will be no change in the sound.
Now how to test? Record a song before modifications and record the same song after modifications. Levels must be precisely matched and the recorded signal should be taken directly from the speaker terminals. Now invert one of the recordings and add them together. At this point, two identical recordings will totally cancel each other out and the output will have no signal at all. If there are differences in the signals, only the differences will be found in the output signals.
This is very much like what Bob Carver did during the "Carver Challenge" presented to him by a major stereo publication. He took one of his SS amps and voiced it exactly like a very expensive tube amp. Pissed a lot pf folks off. He simply compared the signal going into the tube amp to the signal coming out. The difference he dubbed the "Transfer Function". He built a simple filter in his SS amp to emulate the "Transfer Function" of the tube amp. All in less than 24 hours in his motel room at a big trade show.
It was A/B compared to the big expensive tube amp (Conrad Johnson I believe) by a panel of audiophiles selected by the magazine at the trade show and to the magazines credit the report was published. Like I said, it pissed a lot of folks off when some fairly inexpensive SS amps could be voiced exactly like some top of the line tube amps. Now there is a man who is an audio legend, like him or not.

So tell us again how paralleling resistors messes up the signals, so far you have answered me several times and have just danced around it.

Jeff, any outlandish claims that you make WILL be questioned.

There are folks new to audio that read this board and they need to build there knowledge on a firm foundation, not some outlandish claims that can't be substantiated other than by "I can hear it, really I can folks!".
