Funniest snake oil theories
Oh, I agree - my speakers aren't that big (Sony SS-M3, also modded for active) - they're just way out from the walls, on stands. Nearer thy field to me! (The subs are back there where they belong.)

It's nice wraparound stage in stereo as well, but I'm also having great fun with some of these 5.1 surround mixes. They can be a bit of a crap shoot, but when they're good, they're really good.

Watched this the other night:

An Honest Liar (2014) - IMDb

Recommended for snake oil skeptics and believers alike.

Just finished watching it.

Good movie.

Thanks for the recommendation.

That's a good plan.

What's with all these people hearing differences with speaker cables?
Are passive crossovers in commercial speakers so sensitive to cables?

Also, what's the deal with power conditioners? I simply cannot believe that any device cares about the quality of the commercial AC, since it gets rectified, filtered, the noise gets rejected by transformers, and in some cases there's even PFC.

Psychosomatic.

As the rock man in "Oblio and the Land of Point" stated, "Well that's it - you see what you want to see and you hear what you want to hear"

The Point

I'm guilty of wiring my speakers with silver plated copper wire, Teflon insulated, because silver oxide is a better conductor than copper oxide.
I've also made a power conditioner, of sorts, by treating each of 3 double receptacles as follows:
8 wraps around a ferrite ring with the hot wire, which has a 0.01uF cap in front of that ferrite ring, shunting to ground. The ground also has the same ferrite treatment, and it too is between the component side, and the wall plug in side.
Whether this reduces stray RFI or not, I have no way of measuring.
But to me, midday music sounds subjectively more like latenight music.
Of course, aural memory is only reliable for a few moments, but it's satisfying that I've done something to help my system, with spare parts I already had at hand, with no out of pocket expense.

Those people are what is known as "sources of income " for people who are unscrupulous and prey on the uninformed gullible and perhaps less shall we say..... "top heavy". A very bad combo but one the industry is sorrowfully riddled with, (the very subject of this thread.)Those who prey have my contempt. Those who buy into it have my sympathy. It is simply sad

The deal with power conditioners is that most mains transformers, diode bridges and power elco's in audio equipment are almost fully transparant to any HF signal due to parasitc inter winding capacitance in the transformer, transformer core sautration due to DC elements in the mains. Non linearities and parasitic capacitance in the rectifiers and voltage regulators together with limted bandwith of the reservoir capacitors and HF ringing of this whole resonance system of capacitance and stray inductance of the witing/pcb layout. So maybe you can imagine a good calculated mains filter that is designed upon the equipment it has to feed (this excludes most of the shelf solutions) can indeed make a difference

Now if all these elements a power supply consist of where theoretically ideal components then you are absolutely right, any mains grunge does not have a change to come through but unfortunatly in the real world these componesnts are rarely perfect.
