I'm posting this here because I'm not getting any response on the Power forum.
I just finished the whole house remodel, including a new dedicated listening/HT room. I have 6 dedicated lines going into the room from a subpanel. I recently plugged the PS noise harvesters into these outlets and was shocked to find that the harvester was blinking continuously on 3 out of the 6 lines. One of the lines has a PS Soloist installed and still blinking like crazy. Another has a P300 plugged into it. When I put the harvester on the P300, no blinking at all. The amp is Plugged directly into one "quiet" line, but when the amp is on, the noise harvester blinks too.
Question 1: what could potentially introduced noise to the dedicated line? Should I have the electrician rearrange the breakers on the subpanel so these are all on the same phase, opposite the ones for regular wall outlets and lights?
The electrician came back two weeks ago and I had him rearranged the subpanel so all these dedicated lines are on the same "leg". It initially made the lines quieter, meaning the Noise Harvesters no longer blinks like crazy. But they still blink from time to time.
Thanks all for providing great info!
So some of your stuff is going to be problematic.
Though all of the lines into the stereo room should be on the same pole
The dedicated branch circuits should all be on the same leg or phase of the distribution panel, preferably the leg that has the least noise issues.
Unfortunately, some of the very equipment that we love, produces noise that back-feeds ( on the load side of our conditioners ).
Those nasty wall wart power supplies are notorious for creating noise.
I make it a point to plug them into an opposite power leg.
Unless you are fortunate enough to have a utility transformer all to yourself, everyone connected to the shared secondary will have an effect on the quality of your power, dedicated line or not.
How do things sound? Thats what really matters.
It is a very good idea to place the audio breakers on the same phase to avoid grounding issues.
As for noise on the dedicated lines,how are the breakers arranged vis a vis the others? I noticed in my home, normally the heavy current draw appliances are located closest to the incoming line. In other words, the heater, oven, AC, etc, are placed at the top of the breaker box. I had the breakers rearranged and placed my audio breakers closer to the incoming line and that made an audible difference.
No passive line conditioner will entirely remove all noise. IMO that is why your noise harvester is still blinking downstream of the Soloist. Dedicated lines will help mostly with reducing/eliminating voltage drop and some interaction between components, but that's about it. With all circuits in parallel on the same 120V leg, any noise present on one branch circuit will infiltrate the other(s) to some degree.
At some point along the pursuit of perfect power for our audio gear might we ask "just how acute is my hearing?" How many times might that several thousand spent on audio equipment upgrades be best applied to better hearing aids?

I wonder my self sometimes? I'll be happy watching tv and then I'll put my glasses on and it's so much clearer. I'm 43 now and this is my first pair of glasses.
I do wonder if my ears are maybe like my eyes, (out of focus)only there seems no way to tell..
