With the late success in my battle with electricity I was slowly reviewing some of my things. What I detected that in context of good electricity I can set up my Injection Channel much more aggressive, let seat 2-3dB more than I did before (not it is at minus 12dB).
This is of course a form of modifying the speakers while you are still in the process of getting used to the sound of the PP2000; it may be premature.

Irregularity in the AC waveform can be thought of to give the effect of frequency modulation to the signal. The distribution of this variable modulation can impact the audible band. Further, the recording engineers also had to live with this. Not only is it embedded as part of the recording process, but they may likely have compensated for this artifact in equalization.

This complex effect means that most likely using a pure AC source like the PP2000 will demand changes in equalization that do NOT result in a flat frequency response curve. It would be necessary to equalize the system like RIAA, of course not to this extent or in this way, but the idea is the same. As we must decode records made with RIAA response curve to get correct sound from the speakers, we must think about equalizing the system to compensate for the recordings made with bad electricity.

The nature of the curve is unknown as of yet. However, based on Romy's observations so far, the high and mid frequencies may need to be boosted in relation to the low frequencies.
