Do I have a power issue?

Yes, no, kind of maybe, again the term “ power conditioner is way over used, there is no one size or type that fits all situations. My fellow gear pimp alumni in both Audiophile and pro do the world a huge disservice as do those who say “ this works for me I have no issues”. Well did you really have issues to begin with? The best power products are designed to solve specific issues, for 99% of the public they are over kill. Most could probably get by with a simple Home Depot outlet strip with a very simple filter and MOV for protection, well until that MOV does its job then it’s just a piece of wire, of course nobody tells you that as well as the fact that now you have no spike protection and you are completely in the dark.
Now yes I am sitting here with a big old Furman 20 amp voltage regulator, well while it was completely rewired 7 years ago my building is over a 100 years old with about 280 unit with their own HVAC’s 9 elevators plus a giant HVAC for 34 lobby’s, you think my voltage doesn’t fluctuate? I mean KC’s plumbing infrastructure in this neighborhood dates back to the 1800’s you think think the electrical infrastructure is up to date? So yeah you plug a Voltage meter into an outlet and it’s all over the place +- 20% in other words perfect case for a voltage regulator and some isolation. The Giant Class A BEL 2002 amp does not live on the voltage regulator, the PSU in it is basically its own voltage regulator and the way it can draw current quickly means anything that’s going to regulate current quicker than a basic breaker is a no go. Now this isn’t an endorsement of my approach, I’m not saying it will work for anyone else out there unless you live in my building.

Power is the new audio voodoo, If I hear one more time I should have “ hospital grade outlets because they are superior I’ll strangle them, do you know what “ hospital grade” outlet means, really, really means ? Now keep in mind my info comes from a guy who won the Wi Bio Medical Engineer of the year award & the Guy the award was named for ( I called him Uncle Jim) , the guy who ran the Marshfield WI power utility ( we knew him as grandpa) multiple medical equipment reps. All hospital Grade really means is the Ground conductor on both the female and Male connector is a bit longer so that ground always connects first so it can’t arc in or near an oxygen field and cause a fire. Now tell me how that Affects anything unless I’m hot patching? But every power expert says they are the bomb!

Again find the problem isolate it then do some research on how to actually solve it, the bad news is your probably going to find there isn’t a magic box and you need an electrician.

I’d love to see how they “tested” them …

Genset time?

I've quieted a 1500VA enough for my home setup, PM if you want more info.  

Hurricane alley storm season, time for a generator 😁

Trust me after a storm your going to want the fridge & maybe the air conditioner working, short of a Tesla wall battery and solar are not going to buy you much time, a big generator raised off the ground using a crappy pickup as the fuel source is what you want.
All the Generac dealers push the LP/ or natural gas but gas lines break during storms because of the flooding and most LP tanks get flooded as well.

Yeah I forgot you were in a condo😁 funny story the first building we were in hear in KC had a huge back up generator, the problem was the city hand mounted all the transformers in this little man made valley at ground level and the generator was only raised about a foot, so any time it rained hard a transformer would blow and the generator would get flooded. After about 2 years the city raised the first transformer and the building owner raised the generator. We were told the problem was solved, well the problem was they didn’t raise the next 3 transformers in line, nobody realized our transformer acted as a fuse for the ones down the line and the fuel tank for our Massive Kohler generator that was now 4 feet off the ground was still below grade, so of course our transformer didn’t blow but the one a block away did acting as fuse and they ended up raising the tank after the 3rd time it got filled with water! Every year they raise one more transformer!

The issue with esoteric mains power outlets and power cords is what is on the other side of wall?

Something called a power grid composed of miles of non-esoteric cabling, connections, junctions, switches, fuses, breakers, transformers etc, etc.

Unless there are electrical issues in terms of high resistance limiting current flow or grounding problems etc. which are measurable electrical faults which should be diagnosed and rectified regardless, no amount of gold plated, carbon fibre, graphene enhanced mains cable will make one iota of audible difference to the sound.

It ain’t rocket science.

Hell it’s not even audio science.

It’s just wishful thinking.

It's when the Baby Boomers leave the Club...
To the younger Gen X'ers etc.

That wasn't sarcasm.  Genuinely curious if their methods had any validity.

Myself, I just hard wire all my gear straight to the power pole outside my studio. I find the mains panel and the fuses add subtle coloration in the 70khz to 100khz range that really bums me out.  Cheaper too, because you bypass the meter.  (Now that is sarcasm)

I’ve experienced issues with power sockets too. My house had the cheapest power sockets known to man. They were barely functional. I’d get intermittent connection with a plug fully seated. Replaced them with “expensive” sockets (about $3-5 each) and it was a night and day difference. Like cables and a lot of other things, sockets can be so poorly made that it’s not really an issue of trying to “improve” something as it is an issue of getting something to work properly in the first place.
