Yes, and lucid explanation why parallel caps on AC between neutral and hot affect sound does not exist. To make the things worst I can tell you that you can put 4324 regenerator or transformer of any kind after this cap you still will have no bass. It looks like on-line regenerator frat everything to DC and it shell not be any even remote memory of any incoming AC, but it is very much not the case. We have long discussions with right people on the subject; no one was able to explain the paradox believably. There is a company, in think in Colorado or somewhere nearby there, - I do not remember the name – they claimed that they clacked the “secret” and they produce caps that has no negative impact to sound placed on AC side. They very expensive and very secretive. I did not try them and I do not believe in this sonic impartiality until I do try them myself. I also know from my life experience in audio that wherever I see people claim secretive technology or secretive knowledge it almost always means BS, ignorance, lie, deception and inability to compete with results.

Also, yes, to debut the playback when electricity turns bad and you do not know it is very tricky. I spent 2 weeks finally calibrate my playback and now I feel that I would need to do it again when I have my electricity back. That move from 107Hz crossover to 100Hz of midbass crossover, that all time that was fucking with lower bass 300Hz filter – that all was wasted time as my new deadly PP2000 have huge signature in there. My filters are line-lever and to make any filter changes to means to disconnect everything, flip up the big and heavy amps and do some delicate changes. That all is a few hours job, each time I do it. Do I need to send invoice to PurePower for punitive damage?

Funny, but for the last few week I did exactly what you did with VTA on my TT in search for lower bass. Still, I feel that run power cables directly to the breakers were good at the day you tried but it will not be good any day. I do not know how it is in your country but her we have one-two good electricity day per year… With all my current love to the PurePower I would propose that you did not heard proper bass from your playback until you hear it driven from PROPERLY OPERATING PP2000. A stupid statement in my current situation but it is what it is. The only reason I keep enduring this atypical to me masochistic behavior with PurePower is because the sonic result that the PROPERLY OPERATING PP2000 does is light miles better then anything the I have seen, particularly in lower bass.

BTW, I did try to add capacitance to the properly operating PP2000 output to subdue the residual noise the PP2000 has. I remember that 2uF-3uF were negatively auditable in bass. BTW, I do have a feeling that the new units has some extra capacitance in compare to what they had before but it is very not certain and I have very different room not and slightly different bass. I have this feeling because the PP2000 has less measurable noise in output and I presume that PurePower folks just killed with extra capacitance. I do not know if they do it via output filters of juts by caps on output. In the first case it would not be possible to get rid of them as they are in feedback loop of the pulse amp…
