Is there a limit to how good a sound people can appreciate? Like the guy who has his own electric supply, can he really hear the difference or is he tricking himself mentally into believing there is a difference?

The subject of the article (Dr Sean Olive) has been doing research into actual perceivable differences in audio reproduction - he wrote the book on ideal curves for headphones based on blind tests by trained and untrained listeners. I read his blog religiously decades ago - he really cut through the audiophile snake oil.
A better headphone/speaker in ideal room might be able to deliver better reproduction, but beyond that with lossless digital source and spec-conformant player, the result should be equal. Any fancy cabling, power supply, shielding (beyond what's required by the spec) shouldn't affect the result in anyway noticeable by the ear.

In my old apartment, the power was so dirty that anytime one of my neighbors turned on a stove or hair dryer or anything with high induction, it would manifest as noise amd popping in my audio system.
This would occur to some degree even on my electronics that were running on a DC battery separate from the home's circuit. Less intense fluctuations still showed up in spectrograms when recording music.

Well, the dB scale was once created on the basis that 1dB was thought to be the "just noticeable difference". Off the top of my head, I think trained listeners can actually notice differences of 0.3 dB, though this sort of thing is going to be frequency dependent too.
The eq-adjustments you'll find online often have adjustments ranging from 1 to 6dB in different frequencies. That's enough to notice.
Comparing settings/devices, it's very easy to notice. Just play some music on your laptop/phone speakers and move the device around a bit, and you'll hear striking differences in highs and lows.
However in isolation, I think most people wouldn't be able to say if a particular sound source is "good" or "bad". It takes a while for you to clock that, no, it's not the teams/zoom call that has bad quality, it's your headset that's dropping mids.

But can they notice the difference on a random track, not on special test audio? Probably not.

My laptop has speakers directed downwards, so putting a palm under it (to reflect sound upwards) increases the quality.

The fact that audiophools reject blind A-B tests should tell you everything you need to know.

Anyone who has ever mixed music seriously knows the effect of psychoacoustics - your brain is such a proficient signal to noise optimiser, that differences in audio quality are perceptible only for the first few minutes of hearing a given sound source.
This is why mix engineers have multiple sets of speakers, so they can periodically reset their perception. Additionally, it is well documented that the top scoring speakers on Audio Science Review (where people who think linear reproduction of audio is the only job of a speaker) do not align well with the top tool choices for audio professionals, and this is not because they are governed by supersition.
There is not currently a metric for many of the things that become essential as soon as you start listening critically and having to make binding decisions from your perception - will it fatigue me, is the speaker lying to me, dimensionality, etc. Saying these are problems with your listening environment is punting on the problem of the actual duty a speaker is required to fulfil.
I don't see why an audiophile, who is a critical listener, should be any different. They're obviously doing it without a generated artefact from their listening, so there's no data based feedback loop for the quality of their experience, but it's a hobby, so everyone's preferences have value.

"Now, Mr. Olive...."
"DOCTOR Olive! I didn't spend 6 years in evil audiophool school to be called Mister, thank you very much."
