Mani,
I did find it was strange that you were getting from insulation transformer better result then from PP2000. They are very different devises with very different results. The difference is like to play a CD from an audio output of a consumer $50 CD/DVD player and from CEC TL0. TL-0 has some much more of everything that it would not be even polite to mention the differences.
As I told before all your observation about PP2000 work deferent from battery and from grid are due to the fact that you have no properly operating PP2000. It is what my November units did and I have no idea how long before it PurePower made faulty units. BTW, there are reasonably simple tests to verify that your unit does or does not have the problem that my November units has, the testing procedures you will need to get from PurePower.
I do not exactly buy the notion that “your new mains circuit would help get the best out of the PP2000” That fact that regenerator might be improved by insulation transformer before it in fact is an evidence that the regenerator is faulty. Your grounding idea is very fine but they work on the load side and if the regenerator own ground is separated from load. If a regenerators is faulty, if it clips or provide asymmetrical wave then no one insulation transformer or grounding will help. If you truly would like to know how your insulation transformer sounds then run your playback from PP2000 and THEN put the transformer after the PP2000. You will see how much Sound your transformer will eat.
Still, your experiment is interesting in my view as it raises a question if sound of PP2000 might be stabilized by use of insulation transformer before it. I discard your experience as you have difference between battery and grid operation. I discard my own experiments as well and what I did those experiments in November/December I had busted PP2000. Now I have perfectly operating PP2000, moreover with added HF capacitance on buttery. I do recognize the fluctuation of electricity quality but near not as dramatic as it use to be – put in this way – I did not have any truly bad electricity day since my PP2000 was fixed. Now I have grounds addressed and how I might try to put an insulation transformer before the PP2000 to see it helps to stabilize the last minor fluctuation of quality I still observe. I will be posting the result. Warn you that I do not look for or expect any improvement in quality but I rather will be looking improvement in sound stability and grid decompiling.
