When I'm playing music on my stereo from my PC through USB, turning off the lights on my bathroom on the other side of the wall will momentarily kill my USB driver and as a result Spotify stops working. Electromagnetic interference is no joke.
Is this true for every component you plug in?
I imagine this is your stereo power supply.
I oddly would love to hear more.

At what point does it stop being a hobby and turn into mental illness?
Consequences. If it's disposable income, your hobby can be blending $100 bills into mulch to grow a bonsai tree. If you are eating up your retirement at 40, it's a disease. Of course I'm not an expert whatsoever. Just my loose sense.

This must be satire, right?
I wish it was all an elaborate joke, but unfortunately it's not. The rest of that site is just as perplexing and appears to cater to the same sort of people who believe in psychics. Here's one example: http://www.machinadynamica.com/machina60.htm
> he realized that electromagnetic interference from his neighbors’ appliances was propagating through their shared power lines, reducing the quality of the sound he was getting. This actually seems a lot more reasonable to me than the monster cable level of absurdity audiophiles are famous for. When I last visited family my sister's home's electricity exhibited all sorts of overload artifacts. Her lights would dim w…
If you don't actually need UPS, it's probably easier to use an AC low-pass filter to remove harmonics than back-to-back DC conversion.

There is no stupidity limit. Research flat Earth!
For even more fun why not (re)read Sir Terry's oeuvre. Pissing yourself laughing is good for you.

Indeed, and if you think about it, an amplifier is a power conditioner.
Explain to me how an amplifier is a power conditioner, please.
First, it converts line power to stable DC voltages while filtering out spurious signals that could affect the audio output.
Second, the power amplifier circuit is designed so that the output voltage is proportional to the audio input voltage, even in the face of power supply variations.
A well designed amplifier tolerates a fair amount of noise and amplitude variation on the input power line. The end goal is for any residual variation to have a minimal audible effect.
For this reason, additional power conditioning is rarely if ever needed. My source of this information comes from the musical instrument and live-sound side of audio, rather than the hi-fi side. But most mainstream designers do not recommend additional power conditioning.
Of course nothing prevents people from buying additional gear if it makes them happy. And in the audiophile world, there is some interest in exploring the behavior of historical or minimalist designs that might not have a very high level of power conditioning. I'm only thinking about "mainstream" gear.
A normal person uses the audio system to listen music, while an audiophile uses music to listen to his audio system.Earlier quoted context omitted.
Don't confuse the sound of compression with the sound of music being louder. Compression can help with poor quality equipment or noisy listening environments (e.g. cars), but it also adds audible distortion and is tiring to listen to for long. Most dynamic range compression in music is there to trick people into playing it louder (see "loudness war"), and louder music sounds better. Of course, you can get the same be…
> Most dynamic range compression in music is there to trick people into playing it louder That's a relatively new phenomenon, together with the distortion. Compression doesn't add audible distortion, except if it is used in an extreme way to boost the signal so that it sits at close to maximum volume. Compression is a tool that can combat distortion. Reduce the transients; reduce the clipping. Compression can be used…
