Those who do not know how audio sound during the Super Electricity Days they do not know. I do know and I wonder: are the Super Electricity Days have own after-mark. I kind of pissed that it did not hit me early as I might wait for net Super Electricity Day who know how long.
So, what I would like to do is to do a recording during a Super Electricity Day. Let play an PL and output the preamp output to the Pacific’s 88K. Then in a few days what the electricity is regular to do the same recording of the same LP to another 88K file. Then to compare two 88K files. There is a remote chance that it will be difference between those two files, and if it be then I would like to see what the difference would be. That might be very interesting experiment.

Ok, I did it and the results are superbly illustrative I did not even expect that it will be so obvious. Also, it is a first attempt to look at the objective data about sound of electricity that I ever seen. I am sharing all data for you; you make your own research and conclusions. First of all what it is. I made 2 weeks ago a recording. I did not use LP as I initially intended but decided to use a CD as it gives more stable, repeatable result. So, it was a very good electricity day (not the Super Electricity Day but still very good day) and I recorded a file from my CD player. Today was bad electricity sound and I recorded the same file again. The path was the following:
CEC TL0 -> Bidat DAC -> Placette Preamp -> Tape Out -> Pacific Microsonic II in Master Mode ->Linx 16 -> Wavelab 6 at 88/24.
There was no editing or processing of files done of any kind and there was no change of equipment of any kind done. Pacific was working for a couple hours before recording. All equipment, including DAW was running from one single PP2000.
Below are both files recorded during bad and god electricity days. The file sound dramatically different.

The visual comparing of the file also indicate that difference is VERY dramatic. The file above is from good electricity day and below is from bad day.
Here is the 3D diference from 20Hz to 20.000Hz
The data above proves that it is perfectly possible to develop a sonic text that will objectively, without any BS or excuses for deafness or ignorance to measure SONIC performance of electricity. The test might be loaded from USB flash card and measure how suitable given electivity for Sound.

PS: It would be interesting to do it again with and without PP2000. I am sure the amplitude of the differences would be MUCH higher. Now, how to make the difference do not exist?Rerurn to Romy the Cat's Site
