Ok, yesterday I have done my dedicated lines, well my electrician did it but I guess I will take all credit for it and he just get my check. I have right behind my rack with PP3000 and power measuring equipment, on the wall 3 groups of receptacles: One duplex with best sounding house line and two dedicated 100A lines with Nima L15-30P twist lock outlets  each, paralleled with 20A standard duplexes outlets. The Nima L15-30P is 30A rated and I use 40A circuit breakers on each dedicated lines (better quality then 30A breakers). I have two lines each of them represent a half of 240V, each half of 120 do sound and do measure differently.

So, the biggest question: was it worth it? I do not know yet. Last night I have some listening, in fact not me but a local audio guy come to my place and he insisted that sound was significantly better. He however did not hear my playback with PP3000 but only with PP2000 and I feel that PP3000 does cover his “significantly better” comment of his.

I did not do my own critical listening as he occupied my listening char all last evening but my sentiment that with dedicated line I did not have any worsening of sound, I also did not detect that it was “better”. It was basically the same sound that I had since I got the PP3000. I did not have a chance to play with different lines as my current PP3000 has some minor issues to source from different  power lines  but I think we already have discover the might be the reason for it. I think in few days I will be able to use my PP3000 with multiple incoming lines and at that time the dedicated lines will break-in a bit.

Also, it is difficult to make a proper assessment of dedicated line benefit as the quality of electricity in the given day needs to be factored in. So, I think with a few weeks I will be able to get composite feeling if generally my dedicated line gave me any notable improvement across the board. If the damn PP3000 had the remote switch then I would be able to say that, factoring in and relating it to the sound of open lines…

At this point there are a few questions that I am wondering:

1)  Does a dedicated line have advantage if PP3000 is used?

2)  Will Sound be benefited if the PP3000 driven by 240V (essentially a balanced line)?

3)  Will PP3000 be benefited if I put in front of it 240V to 120V isolation transformer?

4)  Can I inflict any treatment over the dedicated line to make the minor residual fluctuation of sound not detectable (presuming that it still come from electricity even thought I have no evidence that it comes from electricity)

5)  Will it worth for me to source the dedicated line not from the very first circuit breaker on my main panel or I need to go and install a dedicated run directly from service entry across a dedicated electric miter?

6)  Would it be beneficial to flip the element of the dedicated line to cryogenic elements?

7)  Would it worth to me to apply any gold or silver high voltage paste to the dedicated line’s outlets and circuit breaker (Johanson or Walker super conductive silver paste, 3M silver paste, Stabilant 22, Solar panels WTS silver paste, Deringer Gold Treatment, ProPlate electroplating, Conducto-Lube Silver grease, Circuitmedic’s Gold Contact Plating, PCB kit from Gold Plating Services and etc, etc, etc..)?

8)  Does it make any sonic sense to use any other power treating devises before or after PP3000?

9)  What to do with my PC (DAW) and hot to power it (dedicated PP2000, insulation transformer and so on)?

10) Shall I hire electrician and to renovate my power service entry?

11) What kind inducement shall I invent in order to make the PurePower people to implement bypass switch into their unit?

They are the question that in one way or another I will be looking to answer in coming time. Feel free to share the results of your experiments on the subject.
