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

i already "partially"catch it...If you roll my post and read it  without trolling it ... 

😉

my deepest respect....

No by any chance, but sometimes some metaphor are more deep and simple and more useful than some other...

There is more evident truth or more evident direct similarity about the lenght of a waiting queue and an the alleged value prize justifying it and the waiting time at the end, than comparing an audio system to a Ferrari but forgetting about the designed track under the wheels...

For sure you know all that and yes i speak too much...

My deepest respect for your kind humor...And patience ....

😁😊

I must be one a roll.

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....

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" ...

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.

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...

😁😊

You are right about power cords and power conditioners, and i concur with your metaphor about painting red a Camry to pass it for a Ferrari... 😁😊

But when these common sense and common place facts are said and well said by you, there is other alleged "snake oil"devices which cannot be put under the rug and be treated as useless because the owner of the costly price tag of some higher end audio system decide that it is the case...

These are the electrical various possible control over the part of the gear and of the room/house electrical grid but also the mechanical vibrations/resonance controls but also the more important acoustical passive treatment and especially the mechanical acoustical control devices...

These are not ALL snake oil creations ...

This is where a low cost system can exceed in S.Q. or rival not far behind it some costlier one, it is here where your Ferrari metaphor ALONE did not work anymore...

Audio experience does not result DIRECTLY from the gear system coming from the store heaven but audio experience result also from the gear system IN A SPECIFIC acoustically controlled or not controlled room...

That is the limit of this popular Ferrari metaphor....It takes a DESIGNED RACE TRACK for the Ferrari to perform , put a Ferrari in a sahara desert caravan track it will not work well...In my metaphor the acoustic control of the room is the DESIGNED track and specifically for it, where the Ferrari perform... Any system without acoustic control is like a car in the deep sand track of the desert ...It did not work well....

Then all acoustic devices are not snake oil or secondary artefact we add or not to a system, they are fundamental like the designed track for the Ferrari...

In my set of acoustic controls devices i use classical Helmoltz method and devices yes , but also unorthodox devices to help my low cost system to not be so far away from SOME highly costlier one... None of them are snake oil...

Yes my system is NOT high-end at all , but yes my ratio quality/price is very high and my experience is not so far AWAY behind system costing 100 more when these system are put in an uncontrolled  room in particular... Thanks to Helmholtz among others...

Acoustic is the key not the price tag....

And all added devices around a system are not ALL snake oil....

Exemple out of acoustic field : tuned mechanical vibration control devices....They are ESSENTIAL....

For me, I have tried different interconnects, speaker cables, power cords, power conditioners. Each has sounded different, for better or worse. So anyone who doesn’t hear any change either has a low fidelity system, or insensitive ears.

We can have opinions about interconnects and speaker cables.
However…
It is exactly opposite wth power cords and power conditioners.

The higher fidelity systems usually have the better power supplies in them and are more immune to what power is coming in. That is part of what makes them higher fidelity, but it also is a sign that they are not cutting corners in one area, and likely also not cutting corners in others.

I would believe that on some lesser quality systems, that these snake oil things might work, but they should work less (If even at all) on systems that are designed right.

We can paint the Camry red, but it only identifies as a Ferrari, it doesn’t actually become one… much the same as a fancy cord does not fix an inadequate power supply design.

U think you are right...

By definition electronic engineering is about trade-off craftmanship...

In some case a conditioner is postive addition in some other case negative... And with the same gear it can also change in time if we change other factors in mechanical, electrical and acoustical working dimensions...

I have yet to hear a conditioner that didnt take away as much as it gave. Far better to start with dedicated lines properly done and then experiment.

There exist electrical-magnetical distortions and crosstalk induced by the gear and there is also distortions and acoustic crosstalk induced by the speakers/ room / two ears relation...

I will explain soon the psycho-acoustic geography of my room in my acoustic thread... 😁😊

"When is it optimal to stop improving the system?" -- is this: *when no more content is added or improved significantly.*

The answer to the question when stop upgrading is related also to acoustic treatment and control...And your own purse for sure...But price tag of the gear is overevaluated much in S.Q. experience and acoustic and psycho-acoustic underevaluated much... Then...

I was hearing new details about sound and more accuracy after acoustic devices tuning or speakers/room tuning...

There is also the acoustic cues and factors that cannot be given by the gear alone in an optimal way and ask for room treatment and control...

Especially listener envelopment/source width ratio and timbre....

This was my motto for years: dont upgrade before the audio system is well embedded in mechanical and electrical and acoustical working dimensions...

I myself for example add a linear power supply for my  dac with success and a lower noise level but the linear supply itself must be controlled  for his vibrations for example...I even add a "golden plate" on it (shungite+copper tape)...

The fundamental mistake they make is to disconnect foreground and background.

You explain it more economically than me i will stay mute ....

The main phenomenon in acoustic and audio engineering are understood in non linear relations...

And " interpretation " or perception  is itself a non linear event ...

Thanks....
