Why do I need power management if I have a great power cord?

I apologize then but i reacted also to the word "snake oil" in your post...

I apologize because sometimes i react too much to some words..."snake oil" for example associated to pyramidal objects ... 😉

I was ok with your post about power cord and power supply , i think the same as you, but the comparison of a costly audio system with a Ferrari is a comparison which had some limit if not completed and a comparison which ask to some addition to be accurate... A gear system so luxury and high tech it is cannot sound at his potential peak in any room no more than a Ferrari on any track will perform the same...

I did it....

The other copper disks and pyramid shaped jobs, I will not comment on.

These devices you see are SECONDARY now for me.... They work but their effect is small compared to my others created devices in acoustic in the last 2 years...

The photo you see in my virtual page is many years ago already.... None of my main acoustic grids of devices are there ...

Why ?

Because i dont want to be ridiculed by people ignorant of acoustic when they will se straws, cardboard empty paper rolls and plumber discraded tunes etc...

And anyway it is not esthetical ....

My dedicated acoustic room was my research room so ti speak.... It is now finished...

My point in my audiophile journey was the creation of an audiophile experience at no cost or very low one... I succeed....It is not necessary to believe me... All my homemade  devices are not equal in degree of improvement for sure but they cost peanuts...The more powerful without doubts  are the acoustic devices...

My discovery that for example acoustic control exceed in power " most"  gear upgrade is a measurable objective  fact easy to verify and which is known by all acoustician......The room is if not the ONLY the MAIN luxury in audio...

What I actually think cannot be proved by what I actually wrote.

The pyramid power has dated back a long time with claims of keeping food fresh, razors sharp, and other things. (I use a refrigerator and have a beard.)

I do not personally use those pyramids, but it’s possible that I have a Bangles LP… I should do, as I like the gendre.

There is also a huge difference between making ones own resonators and foil covered pyramids, and selling magical boxes of dirt and other things at obscene prices.
No one would buy the pyramids at $1, but at $1000 it is more likely that a queue might start forming.

By the way the pyramidal shape of the device in my photo is a red herring for some who judge easily , i also used other forms because the form is of no importance here, the device is made by 2 materials : shungite +copper tape... The essential fact is the specific minerals here and his mass... But some shungite dealer send me pyramids and i bought them because they were cheaper ...I also have spherical one, plate one cubical one , the form does not matter save for easier placement...I used them all along my electrical grid...It is only one of my experiments...

Then this "pyramidal" shape is not my "tin foil" hat... 😁😊 And i cannot sell 1 dollar of shungite material to someone else 1000 thousand bucks...By the way....

i sell creativity not "snake oil" ...

Here you are more right than with your Ferrari metaphor...

Most people indeed laugh at my 1 dollars homemade devices, pyramids or not... they will not laugh so much for sure if they were costly and esthetical... You are right about that...

I laugh the last though... 😁😊

I dont bought  tweaks nor upgrade...

I dont need to....

Some experiments and some knowledge could spare big money....And yes my car will never be transformed in a Ferrari but it roll on the same designed track very well and perform at his best there not so far away than some can think behind the Ferrari .... After all my gear (car) was well chosen... 😊

And i am not jealous of all those who put their Ferrari on ordinary undesigned road anyway...An ordinary car can beat a Ferrari in the desert...

My deepest respect to you for your patience... And my best....

I must be one a roll.
