You say that the dimmers are on PS3 line only. However, when you turned dimmers on, the PS1 And PS3 lines had "changed" sound that you are "not convinced" is inferior to PS2. First, how would the dimmers affect PS1 since it branches before the house line directly to the PP3000?

Do not forget that dimmers to a different degree affect all lines. The PS1 and PS2 lines are the same secondary of step down transformer on the poll with neutral acting as center tap. So, the events that took place on the one side of the secondary naturally propagated to another one. I did make a phone call to a transformer guy and consulted with him on the subject and it is a bit complicated how this penetration takes place.

Second, are you saying that both PS1 and PS3  were "changed" identically or in highly similar fashion compared to PS2 (ie PS1 and PS3 now sound the same albeit changed from what they sound like without dimmers on) OR do you mean that PS1 and PS3 both had "changes" to the sound but in distinguishable ways between them?

I would not insist in one or other. I do feel that it is not as direct and straight forward when PP3000 involved as it not only “fix” the problem by regeneration but it looks that it also equalize the condition by squirting into the dirty lines own noise. It would be VERY beneficial to hear the sound of open line with PP3000 plugged into the same line but do not power system from PP3000. This would give a lot of data to interpret the result but to dot I need to have a bypass switch in the PP3000. I have many components and to unplug them and then to plug them in different outlets is very unpractical and too troublesome.

Third, I assume you realize that the term "not convinced" implies a significant possibility that you will be convinced. Therefore, what were the nature of the changes that left you "not convinced" that Ps1 and PS# sounded worse than PS2 when the dimmers were on? Thanks for all your effort in examining these issues BTW.

Sure, everything is on the table. This is why I insist that at this point I do not have any even preliminary concussions. It would be very simple if I plug the PP3000 into the dirtiest like and had worst sound but it did not happen. So, it will take more efforts, more time and more methodological purity to figure out what would be optimum configuration.
