Hello all , i know this topic is almost about pp experience but since im experimenting with electricity i like to share some thoughts here . I builded a dac using very high quality components . As you know the power supply is critical . So i decided to use dc from 24 ( 2 x12v)  volt batteri and listen to changes , i now assume dc from that battery is like very pure electricity from ac , regardless of what element one need to purify it . So it is not just the noise that become quieter , the istruments feels different , feels like they are tuned now . So i was wondering that pp working from battery might have the same effect , or similar effect and when connected to ac , noise must become part of the circuit somewhere . Anyway I will build another power supply , this time with a much larger capacitance to see if theres some effect with same voltage but much more capacitance . It seems very difficult now to feel the instruments the way they feel with dc . I think lower level (little signals) are very sensitive to noise and one must take care from the lower level signal up to the amplifier , i do not know what effect may have pp when connected to ac in the lower level signal 
Joaco,

The this topic is looks like only about PP experience as I found that PP works wonderfully for me and I kind of hijacked the topic with my PP fixation. Still, I do keep my eyes opened and always am welcome to the fresh idea as ultimately this is not the thread about PP but about way to cure electricity related problems. BTW, not further then 2 weeks back I was testing another power-curing devised that the manufacture assured me was absolutely revolutionary. Furthermore the manufacture insisted that without his devise I am “hearing only 20% of music” (this is direct quote!!!) Expectedly the devise worked like shit and went back to the manufacture. So, I would advise do not feel that the thread only about PP, even though the presence of PP very much diluted my acuteness to find an mythical “ultimate” solution.

Now about DC. This subject did pop up multiple times and generally I have anti DC attitude. Let me to explain my reasons. There is no doubt that putting your DAC on DC you might get substantial gain in sound. However, why you feel that your power amps, your phonostage, your CD transport would not be identically benefited from running by DC? To make an experiment with conversion DAC to DC and to prove to yourself that DC is better than dirty electricity from wall is fine. However, at this period of my life I have absolutely no interest in conceptual experiment, proves and evidences.  My interest in practical, factional solutions and the only viable solution that I see in DC word is to put the ENTIRE system on DC. Unfortunately to an entire playback from DC is very much not practical.  If the objective of my playback were for instance to make a single transfer from tape to digital then DC operation would be fine. However, my playback runs all time and for dally use I see no way to have it DC-operated, unless I bring home 1000H/A butteries and rebuild my all equipment.

There is another aspect: we do not know how butteries sound. Let me to explain what I mean. There are people who use butteries bias. They in series with grid of tube put a small 3-4V buttery that is enough to set the bias. So, if you use at the experience of those peoples then you will see that they coastally discovers that each brand, make or even vintage of the buttery has own sound. I presume that the same would be applicable for DC power gear. How much we have a chance to experiment with it?

There are other reasons what I do not feel comfortable with butteries but you got the idea where I am coming from.
