Romy, this is very interesting indeed. I'm assuming that the sonic difference between these two files is in line with the sonic difference you hear between bad and good 'electricity' days when you're just listening to music, with no recording chain involved? If this is indeed the case, then what you've done here is astonishing - a clear indication (to me at least) that what we're calling 'good/bad electricity days' are a bigger determining factor in the final sound than probably the hardware itself.

Surely the root cause must now be explored. You've mentioned before that these differences exist even when the PP2000 is in battery mode (i.e. totally isolated from the AC mains). So can we confidenty eliminate electricity from the equation?

Although I don't want to propose a strong hypothesis right now, can I just say that I seem to experience a similiar (although somewhat smaller, I think) effect by using a 'Schumann Resonator'. Maybe I should repeat your experiment with the SR on and off - I suspect the results might bear a striking resemblance to yours...

Yes, Mani.

The result is very interesting and sonic difference between the file is very auditable after the best first note. In real life the difference would be much higher as at good day and bad day the playback truck will be performing differently. What I captured was just the recorded part, which is fracture of the full difference.

If I knew that he difference would be so visible then I would do multiple tests, with PP2000 is in battery mode and a few other. Now to do it I need to wait another good electricity day. I do not have too much motivation to continue this, I have more interest to address the problem generically instead of continue to study problem. What annoys me is total indifference to the problem by the people who are trying to deal with problem proficiently. They make some kind of devises that work good enough to generate sales and they do not go for a full, global, deep addressing of the problem. I do not knock in the door of PS Audio, PurePower, ExectPower, Acuphase, APC and many others. I juts saying that the similar and much deep research had to be done years and years back and very much not at my armature level.
