Furthermore today to insult the injury it look like my theory about the PP2000 “transparency” to input noise blew in my face as today the wall electricity sounded much better than the from PP2000, that is what I did – disconnected all my regenerators and drove the playback from my dedicated lines.
I would like to ass some comments to what I said above. Yes, last night the wall AC did sound better then my “newly revised” PP2000 running from AC. But that “better” need to be properly understood.

My bare AC line last night sounded very smooth and very round. It was no lower bass as good as my older version PP2000. The entire lower MF was very confused and very badly articulated in compare to my older version of PP2000. There was no “control” over midbass. The older version of PP2000 has phenomenal authoritative control over this region and this control was across all dynamic range. The open AC lines sounded like it had very under-damped bass with some kind of cloud of puffy upperbass that was changing with volume BTW.  However, I still find that the open AC lines sounded better. Why? Because the open AC lines did not has this cocoon of noise that surrounded each single note across enter spectra. This absolutly did not exist in my older version of PP2000 and if it were I would never use the PurePower regenerators.

I do not know, the PurePower people claimed that they do not hear any difference but I very clearly here it from another room. Any single woodwind instrument sounds like a burst pneumatic pipe that discharges gas into fog. How somebody can claim that there is no difference I have no idea.  Anyhow, last night I chose do not use the PP2000 as in that night even the open AC lines did not do anything good but they did less harm that the “revised” PP2000.
