I just thought about the huge new commercial marijuana operation is just a couple miles down the street. It may be up and running now. Hmmmmm.

LED lighting fixture drivers can be switch mode or linear. Bet they bought fixtures without consideration to quality drivers and only consideration to price.

i too run a prima luna dialogue preamp in my otherwise PS Audio system. cant believe how good it sounds after adding the P15. so much music. the 300s must be amazing. i currently have the 250. which sounds very good with my acoustic zen crescendo speakers. does have a little hum or noise audible thru speakers when not playing. not sure what that is. but i love sound of the system.
For the new system I am building my dealer strongly suggested I do without my P20. I was listening to him on this issue at first but I have since decided the P20 is more important to me than listening to music. So at the cost of yet another expensive rack it will have a place in the new system. And now it will sit on special feet in a special rack designed to eliminate vibration. Plus it will get a new power cable way more expensive than the Shunyata Sigma it now has. But wait, it will finally be connected to a dedicated 20 amp circuit instead of the shared 15 amp circuit it has been connected to since time began.
I was a fool to think I could do without it.

Congratulations aangen…great decision on keeping your new P20…
what a dumb dumb knucklehead dealer…
What did this dealer offer instead ?
Again congratulations!!!
I have five dedicated 20 amp circuits with Furutech GTX power outlets. He said to just use that.
They were being used for my theater setup, but the new system is going there because of the dedicated circuits… He is a very smart guy, he might even be right. But no matter…

That’s very good having 5 dedicated lines…however a dedicated line
as good as they maybe, and improve our systems…can never correct
for the thd power robbing polluted ac sinewves…
Dedicate lines plus P20 = WOW
Your dealer may know somethings but to suggest that you do without

lacks understanding of the value having the P20 supplying power even to
your power amps.

Call me cynical but many dealers won’t recommend something they don’t sell.

OK, you’re cynical.

True, but to tell aangen the following is absurd…thoughtless…
dealers have lost clients with such statements…

amazing to me …
Calm down Davida. The gear I am buying, Gryphon, addresses dirty power internally. They spend a great deal of effort taking care of it in each component making the need for external attention less, if not completely unimportant.
The amplifier designer at Decware offers amplifiers that have options of additional power supply circuitry that is intended to clean up dirty power. When a friend of mine asked if he needed those upgrades and mentioned he had a P15 Regenerator he was told no, he does not need the upgrade for power due to the regenerator.
The man I am dealing with is held in very high regard in the Industry, and recently had a full page article written about him in Stereophile. His name is George Vatchnadze and he owns Kyomi Audio in Chicago.
Pretend it is possible for people to know what they are talking about. It’s easy and it’s fun.

I’ve also had A/V dealers recommend against using regenerators in my system. I was told they are good for urban areas where the demand for power is high and in apartment buildings. The Audioquest Niagara products were recommended to me. I take the info from all my sources including forum members and try to make the best decision based on what others have experienced. I have read mostly good and some bad on both the PS Regenerators and the Niagara power products. Reading about the P20 is definitely has me intrigued!
I have Decware components with the voltage regulation that Steve Deckert used to say made a regerator unneccessary. I can clearly hear and prefer the sound of these plugged into my PPP, P10 or P15! (His power regulation designs really clean up the power–they do, but the regenerators still improve playback sound! Having both is a good thing!)

I was having problems with McIntosh MX150 HT processor and the Video outs after buying the P20. The video would stop displaying after power up. It would entail having todo full reset on unit to return functionality of video.
On a hunch I swapped it over to a high current outlet. The issue has since disappeared. The power up implementation is different on high current taps related to equipment protection designed into the P20. The high current taps allow unimpeded flow without the same P20 spike protections on voltage. I surmise the current inrush of bringing my system up was affecting something in the circuitry of the processor it didn’t like. If it shows up again I will try a direct wall connection.
Thus I can see designers, dealers, or companies being wary of equipment that may exercise warranty claims and cause investigation. My original issue caused me to exercise McIntosh support who got me back functioning. Knowing I had just got P20 and not had issues prior saved me sending unit back and investigating why it fails on P20 low current taps.

No, the lights are no longer blinking now that I’ve got things separated. Solid wire 10AWG from the Breaker panel to the old 220VAC outlet (now replaced with a junction box) and then Marretted (Wire Nuts/Wire End Connected) to 10AWG Stranded with flexible Aluminum Conduit run through the exterior Garage walls and then punched through into the living room wall where my audio rig is located. Terminated with the PS Audio “classic” Wall Outlet. The PC/Video/TV has a separate 12AWG Solid wire running from the Breaker panel into the living also with Aluminum conduit terminated with a Hospital Grade (orange) 20A wall outlet.

That step increase in line distortion could be from a large industrial load as you hypothesized, but I’d probably suspect something closer to home…like one of your neighbors (or you 
). Unless you’re in a rural area, you’re probably sharing a distribution transformer with at least 4 other houses, maybe 5-6 others, depending on the system and size of the transformer. Everything using electricity in every house on that distribution transformer is basically connected in parallel at the secondary winding.
Regardless of the cause, I’d recommend calling your electric utility and asking them to come out and investigate it. While there’s no actual “spec” for THD on electric distribution grids, almost all utilities have a “power quality” group (or equivalent) that will come out and investigate issues with PQ, and if they determine that something’s outside their target parameters they may be able to help with mitigation.
If you do talk to them, be prepared to hear them chuckle under their breath when you tell them that you use an AC regenerator to power your audio system…like most of the uninitiated, they won’t get it…

It is very rural here. There are two neighbors that may be on the same pole mounted transformer as me. One is for sure but I haven’t looked to see if the other one is. None of us have added or have any high draw devices attached to the grid. The next house besides us three is 1/4 mile away. The large Marijuana grow operation is a couple of miles away.
I will call the utility most likely in the spring and see what they have to say.
Thanks for the info.
At least that high THD is getting cleaned up and an output of 0.1 THD is great.
