Trust me...i too would love to get the full breakdown of every component...after all, i'm an audiophile and its fun to see these things. That said, i would be embarrassed to go bother a physician literally saving lives by saying...hey...what percentage of the uplift in performance was from this particular cable vs the power conditioner...and did you compare the Denali to the Venom, etc?
I wouldn't. My dentist was prior a mechanical engineer and the best dentist I ever experienced. He was into this stuff and great to shoot the **** with both in and out of office.
BTW, lest i forget to say it...i appreciate you are trying to be super specific about cables vs conditioners...i can respect that. But in a hobby/passion where sometimes we get NO scientific evidence at all...or very [very] suspect 'measurements'...i think it is a solid data point that these guys shelled out thousands of dollars on power cables [yes, yes...in addition to the power conditioners]...and i personally suspect the power conditioners did far more for the systems than the cables. That said, i am intrigued to see they also bought the power cables and have made them part of the standard set up for all their monitoring setups.
I'm a big fan of balanced power for noise reduction myself. I think that should be the first step in any system. Fully balanced from outlet to amp and everything in between.

I have heard that from a number of people...we had the option to put something between the 'power coming in from the street' and the part of the panel running to the system. Mainly for cost reasons, we did not do it. But we have the future option to do so...is that what you recommend?
I have multiple lasers in my factory and had issues with banding , variable output and beam quality until I installed pure sine wave ac/dc/ac inverters for them.

Pictures of the noise spectra of an Audio Research preamplifier, single ended output with volume at 65. top - with a cheap power stock power cable. Lower - using a Shunyata Mamba. Sound unit was an EMU, nothing was changed between photos except the power cords. A second run returned similar values with a difference of .4 dB between power cords. There is no absolute calibration, but a CD with 1000Hz at -60 dB shows -70 dB. In balanced mode the mains peaks would reduce significantly. All equipment was connected exactly as if the CD was playing.

there's some interesting hypotheses being posted.
All of which I suspect, are aimed at changing other people's minds.
This misses the point of the thread.

If that test was what changed micro's mind, why does that miss the point of the thread?
That is unless you are addressing your post only to those that still haven't changed their opinions that power cords don't make any sonic differences. If that had been spelled out in our OP, a whole bunch us that shared our opinion changing experiences need not have bothered to take the time out to participate.

As I've said before, I'm asking about what would change your current view.
So whilst it is interesting to read about the experiences that led to people's current view, that is specifically not what I'm asking about here.

People with a different opinion posted in this thread interesting comments concerning measurements and power cables. It is natural we debate them in the thread.

If course. It is very interesting.
And this thread so far has been on the whole, polite and respectful. I believe part of the reason for this is that the emphasis has been on discussion rather than anyone trying to change anyone else's mind
Tough one. No chart will change my mind and neither will an ABX given that I do measure and have conducted tests myself. I do think however that eventually my hearing will continue to degrade with age and at some point the differences will be so small or non-existent (no longer obvious) that I will simply go with the most basic requirement and that being that the system just works (like when my acoustics were so bad PCs were the last of my concerns). I will however continue to listen to music 'til I'm totally deaf or die, whichever comes first.

Thanks - the software could create screnshots and save them, but the whole system was laying on the floor and it was much faster just taking photos of the screen with my cellphone. All measurements were carried in SE, my ADC does not have line level balanced inputs. The second runs were just to confirm if it the difference in noise was not hazardous.
Actually this thread is not about anything being used as proof to convince others. It's about what would convince anyone individually. It's therefore not relevant if that individual's proof is not to the liking of anyone else
With all due respect, perhaps what you are seeking is not something that anyone CAN reliably predict or anticipate but only something that can be known or understood once it has actually been experienced? I have been putting systems together for over 35 years and used a vast range of equipment over that time and rarely have expectations been perfectly matched by experience.
