Indeed, this is a reference to how important electricity might be. After last night, I almost feel as though my equipment is a much less important factor and takes a backseat to everything else. At this stage, I am thinking it makes sense to park my other audio projects for now and really focus on getting the electricity consistently as good as possible.

Ok, you got it. I felt this 15 year back but during all that time I was not able to find any solution.

Goal is to remove volatility and raise overall level to last night's level. Next week I meet with a retired power plant engineer from GE who does a lot of tinkering and I will pick his brain.

Please keep me updated but I do not have high expectations. I did speak with number of people from those fields in past – they do not recognize the categories by which we, the audio people, understand the quality of electricity.

Now I would like to bring a bigger picture...

Two days ago sound was spectacular, last night no so good. Mind you that both of the days have absolutely identical wave forms in the wall and identical amount of distortions. Explain that!  A reader of my site wrote to me yesterday:

“…. there is an obvious big factor at work. Most of the problems with utility power quality are caused by industrial and commercial users and their equipment - plus the utility switching and generation adjustments to accommodate them. Big snow and ice storms = dramatic reduction in industrial activity. Even industries still operating have reduced shifts and reduced processing.”

I am not sure that I agree with it as there was no change of distortion of waveform when electricity sounded good and sounded bad. Also, I do not know how in his country but in US I did not see that industrial slow down during the snow storms. I think the explanation is in more favoriteable transitions condition for electoral wires, but this sound as ridicules as  explanation that   industry got to halt what  there is 3“ or snow on the ground.

This problem with electricity need to be addressed as the electricity problems have deeply imbedded itself in all audio evaluations. Just before the snow storm, what electricity was not so good I visited local guy who show off his playback with new MF drivers. He played to me own FM recordings. It was amazingly horrible. Then I played attention that the name of the files was no mine but he added to my name. I asked what he did with filer and he explained that he used one of those horrible digital toys that extend dymick of the files.  I asked to play the original file, the sound was instantly fixed but as many FM it was very dynamically compressed.  Just for fun I was playing the same “compressed” file 2 days back, when the electric was spectacular. The file still was dymickly compressed but auditable experience was at absolutely different level – it was 10 times less auditable compressed then it was before storm and it subjectively sounded truly more dynamic then any CD we played before the storm. Interning that the guy does use the PP2000…

The mistaken concussions that we make about sound of audio that in fact the sound of electricity are enormous. Last night a sire reader sent me email:

“I have had the exact same experience you and scooter described.  This evenings listening was bad compared to a few days ago.  I am glad to read your post because all evening I have been adjusting VTA/VTF, thinking this was the reason everything was off.  All the adjustments did not help.”

How idiotic is it what a person hear bright sound begin to fucking up with VTA/VTF? Incredibly idiotic but what would you propose to the person to do if he knows that he changed nothing and that a day before he has absolutely different sound? Mind you that the person does use PP2000…

The two examples that I brought are related. First of all I do not know what version of PP2000 they have and if this units operate properly. What I said that last night it did not sound so goof I did not mean that it sounded as bad as my November wrecked regenerators sounded. The November PP2000 was unlistenable. My new PP2000 I described last night as “sound not as good” but it was in comparing to a day before when electricity in the wall itself was truly stunning. The sound was “not as good” but acceptable and not “unlistenable”.  I am sure that if I did not run PP2000 then it would be much-much worse. Still, it look like PP2000 do inherent partially the sound of the original power lines. The PS audio power plane did the same but it fucked up sound on it’s own, the PP2000 looks like provide better result but not the ultimate result.

So, if we presume that Pure Power will fix two my remaining PP2000 to the level of my current one then where I see the refocusing efforts might be? The PP2000 has already a small 470uF caps bypassing this battery. That is very good but might not (or might) be enough. I would try 60000-120000uF and will see if it makes any difference. To run one regenerator after other might be a good idea, and I would like to have option to have second regenerator not switching one. I need to reinstate my efforts and to rebuilt the Avicenna - it is linear devise and it will not have problem to work before or after the PP2000.

The biggest problem however is the testing procedure as whatever you test you are not familiar how today the electricity sound. I can say it by ears but I do not know what to measure in electricity to associate the auditable with objectively measurable. What I think however is absolutely necessary is PurePower to take their hand out of pocket and to give to us a bypass switch. The bypass switch has already existed in the unit and it works very nicely. All that is necessary is to run a two wires from the element that control this switch to a jack on the back of the unit (did I said the button on the front of the unit?). Only God knows why PurePower did not do it already. The people who sell PP2000 will have a good demonstration tool about PP2000 effectiveness. We do need the bypass switch on Pure Power.  The bypass switch will allow to monitor the quality of electricity in the wall and to build correlations. Having all my gear plagued into PP2000 I have no way to do it besides to re-plug everything. This is ridicules!I need a bypass switch on PP2000!
