Post Subject: A new dedicated power linePosted by Romy the Cat on: 12/20/2011

I will be making another experiment tomorrow and will try to install a new dedicated power line for audio. I say “another experiment” as the dedicated line that I installed as soon I move into the hour did not sound good, I have no idea why.
This time I will do slightly different. It is be 240V 6ga copper run but not into the walls, along with the rest of the house wires but directly to the dedicated power receptacles behind my playback, in the diagonal of the house, pretty much perpendicular to any power wires. It will not be too ugly and the run will be at the selling of the basement, well it will be ugly but it is basement, who care how it look like in there.
I did some research about circuit breaker and chose one model that I feel better. It is two-poll 40A breaker; I was not able to find this type for lower current. So, it will be 40A power line terminated with L5-30P power outlet, rated for 30A. The PurePower people accommodated me with twist-lock power cord for my PP3000. I do not know what gage wire it will be use but I presume it will be 30A rated as well. The audio circuit breaker will be the very first breaker in my first main power panel, right after the 200A main breaker. The 240V feed will run just behind the location where the PP3000 installed and then it will be split on two half of 120V. Let see how it all works and it gives any better sound then my utility power output (that I admit sounds the best in my house, I have no explanation why.)
The idea behind this dedicated line is to minimize the amount of noise that goes into PP3000. I use a lot of dimmers in my listening room. The SS dimmers, in the way how uses nowadays are one of the most horrible things for sound. If you have one single active dimmer in your house then you audio NEVER sound right. I have zillion tests and experiments about it over the years. The PurePower regenerators absolutely immune to dimmers, I mean I can use 10 dimmers in my listening room and the sound, if I power everything from PurePower is undistinguishable from sound with no dimmers at all. (I can very objectively measure the noise from dimmers outside of PP3000). Still, if the PurePower does not worsen sound when dimmers are active then it still might be beneficial to power PurePower with cleaner power lines. I have refrigerator in house, the heater pumper, the pool pump, the house lighting, and all kitchen appliances, at least 3 computers all time on (2 of them Compaq and HP Servers with dual power supplies), UPS station for the servers…. They are not a lot but they do produce some local noise that might (or might not be) worth to isolate or at least to minimize.
Again, I am not confident that this new version of dedicated power line will make any difference but the only way to say anything is to try. The proper way to do it would be to run a dedicated parallel run directly from service entry, across a new dedicated power meter and to own dedicated 100A entry panel serving ONLY ONE dedicated audio power line. I might convert this line that I will be installing tomorrow into something like this but I need to educate myself about sonic consignees of power meters. Perhaps I will be the Phase 2 of the project and it will not be difficult to do if I chose to go there. Let see if the Phase 1 will be beneficial and if it was then I can take a notch further.
So, if I have no posts after tomorrow than I have electrocuted myself.
