You have an unusual situation because you have so many dimmers (one type of device).

Well, the unusual situation is only as experimentation. In the house I bough pretty much etch light switch had a dimmer. I have removed quite a few of them and left only 12 or so left, excluding bedrooms. I however hardly even use more then 1-3 during listening and since I converted my main listening light to non-dimmering then it will be just 1-2 dimmer that I feel do not impact sound, not to mention that one of them is sitting on another phase-split.

Power regenerators: They seem to behave as another component in the audio system rather than something apart or preceding it. I had a PS Audio power plant at one time and while it did some good things It was inconsistent in its effects. I assume from your experience that the Pure Power regenerators are better but they also seem to behave as components in the audio system.

I more agree then disagree. It is very easy to go astray with recognition of power regenerators as some kind of power improving devises. For sure they do improve power but they also have own sound, own sound that might not necessary relates to the power improvement, or put in this way: relates but not so straight forward. I happened to like a lot how the Pure Power sound, is it strictly related to improvement of electricity? Hw, perhaps but I do not have a definitive answer. Put in this way: if I run Pure Power Company then I would consider making a class A or A/B amplifier with Pure Power instead of power supply…

...I hope y'all are attending to AC polarity alignment, else many of your decisions may be erroneous. I've written so much about this perfectly audible phenomenon that I don't feel like doing it any more, so I point you to an excellent comprehensive article, beginning with an excerpt.

I did not see you write or say anything about AC polarity; you constantly keep stressing Acoustic Polarity but not the AC polarity. At least I did not witness it. Anyhow, AC polarity is for sure a well know phenomena (it was multiple times mentioned at this site) and no one argue that it has to be properly handled. Thankfully with proper following electrical code and proper attention with equipment the AC polarity shall not be a problem and it take care itself.

WHAT YOU NEED TO BE AN OBJECTIVE SCIENTIST. Almost all of your audio equipment has a transformer in it that serves as a source of power for the circuits inside. Not all manufacturers hook up their transformers so as to minimize voltage leakage to the chassis, otherwise called the "chassis to ground potential". One can measure this by purchasing some of the most expensive objective testing equipment known to man and Julian Hirsh. What you will be measuring is the amount of voltage running around in the chassis of your audio stuff. The preferred voltage is the lowest voltage, which will save you from making dreadful subjective decisions.

Actually AC polarity has nothing to do with voltage leakage in transformers. I do not know what Julian Hirsh measures but flipping AC polarity you do not deal with voltage leakage. Regarding the article. I did not read it. I glance from the end and find a reference to Bybee-Sucker as the best AC line filtering device of its kind”. I do not know who wrote it but he is in idiot as Bybee devises are piece of crap, made to use only by deaf morons. 10 year ago I participate in blind test what I with 100% accuracy was able to detect the presence of one single Bybee-Sucker in system – I truly hate that shit and I discard any authors to patronize the Bybee crap.
