Power management for best sound.

[Oukkidoukki]

When I plug active monitors and dac straight to wall outlet sound is somehow better vs using extension cord. Same effect is seen in my plasma tv, from the wall outlet black is deeper and pic seems to be more ”right”. Maybe powercord cause voltage fluctuation etc. , I dont know. I have tried different ( allthough all cheap ones ) extension cords, but effect remains. I dont have enough wall outlets for all of these. Is there extension cord or device that can solve this issue? Thank you.

It's placebo.

Clearly you are not right.

Your are imagining things (expectation bias).

Ask yourself why would the last few feet make a difference when the power lines from the power plant or nearest substation run for a much longer distance.

Since when is ChatGPT scientifically correct?. It just sums up the nonesense of the internet.

 

[Oukkidoukki]

How about google then? Shit also?

Get a voltage tester that has a plug. Test the wall outlet. Test the extension cord. Is there a difference?

I do suggest you make sure your extensions are 12 gauge wire, assuming that is what is in the wall. Some are 14 or 16 or 18, but look pretty thick.

 

[Oukkidoukki]

Ok, thank you. I check those.

From my understanding of a plasma screen - and maybe you can ask chat gpt since you have faith in it - black colours are when the cell is off, as in zero volts. So voltage drop (even if it did exist across an extension cord) could not effect the deepness of the black.
And for your amp I believe the power is step-down immediately from 120 (or 240) AC volts to 12-24 DC volts.

In other words, it’s not an issue unless your extension cord is damaged rubbish.

Why ask here when you've got ChatGPT to give you better answers?

Which length, which AWG ? It would be very unlikely that you get any voltage drops unless your extension chord is both extremely tiny and very long...

In case you choose to trust ChatGPT better than the ASR contributors, please do not waste our time by creating such a thread, then.

Thanks.

Waste your time? I ain’t have any power over your time……it’s 3 meter , don’t know about awg, but it looks like that.

All good. Nothing else needed.

Any voltage variations caused by your energy provider are much much larger than any from the power cord. Plus the built in power supplies in your amp, TV etc are designed to “equalize” power variation on the input side and provide stable power.

You seeing a difference is imagination.

No, discuss it here, get explanations and advices, then wait a bit and ask ChatGPT again

Well, it's indexing the same shit ChatGPT "learned" from, so obviously yes. Just think of ChatGPT as a "next word" simulator, not a system which somehow knows good data from bad. There's been a flurry of articles in literally the last week about how Quora is even worse than it used to be. Hard to believe, given everyone's bio would make you think they were some sort of expert/authority.

Pay attention to the last part:

The practical effect of this is negligible under essentially all situations, but it is real none the less.

The voltage drop over a normal extension cord connected to normal household electronics is absolutely miniscule.

 

[Oukkidoukki]

Ok, weird that google and chatgpt says that there can be some issues, but here its like absolutely no issues.

 

[Deleted member 48726]

To get the best sound and the best picture quality you need an auto transformer in the end of your extension cords to mitigate the problem. One for each extension cord you have.

That's because the web is littered with mysticism and overconfident ignorance, and ChatGPT uses those things as its reference.
