Might want to try the search tool. This discussion had been had multiple times
To expand a bit, most class-D amplifiers use very tightly-regulated supplies that inherently (must) reject line noise and voltage variations. Any power supply should provide very high isolation from the input power source, since it converts from AC to DC with massive filtering on the DC side, but class D amplifiers even more so by design and implementation. Furthermore, class D amplifiers (and the switch-mode power supplies usually used with them) operate (switch) at frequencies well above the audio band (no more power supply noise in the audio band, hurray!) That means they will not benefit from filtering on the input (wall) power source.

What do you mean by this?
Not enough to be worth it.
But some common mode filtering is good practice to reduce EMI from switching powersupplys and Class Ds

I agree, I add a Corcom line filter when I build a class D amp, from an abundance of caution about line RFI/EMI.
No.
As a rule of thumb, your system is limited by the weakest link. And the weakest link is never the power supply, any power conditioner will be a waste of money. Spend money elsewhere.
Not an absolute list, but this is how I would spend money upgrading my system, in order of priority from high to low
speakers > source > dac > amp >>>>>>> cables >>>>>>> power conditioner and other gimmick
and don't forget room treatment and correction.

I need some advice regarding the power delivery to my audio components. My primary need is to get some sort of a power sockets extensions, since I gave only one power sockets available near my audio devices.
I got a good deal opportunity for the used Adept Response aR6 unit for €1200, so I like the idea since I can get six power sockets with some filtering and power surge protection. Do you recommend to take the used unit or to get a quality power strip, for example Supra along with some quality power cord for devices?
Thank you in advance for advices.

Only use AC power products from commercial/industrial providers. Only use products that have a safety sticker, like 'UL' but not 'CE'.
Don't expect any difference in system sound.

Just get any old power strip, and don’t waste any money on power cables. The ones that came with your equipment are fine. Do you need surge protection? Most EU countries have decent power delivery… but if you want it, surely it can be had for way less than a Supra strip. But if you like the looks, go for it!
Good luck finding a European power strip with UL…
Why would you want to spend at least € 2850 for something that your amp should have solved in the first place?
That video is a load of nonsense, don't watch it!
Have you seen the whole video? It´s not all about power conditioner - he goes through everal steps, starting with electrical installtion, then powersupplies, then filter then cable (he´s also mentioning that there are many filters which are nonsense, e.g. not filtering below 50Hz and over 800hz, something that - as I understood - was also critized from amir, point 1 at conclusions https://www.audiosciencereview.com/...evo3-aquarius-power-conditioner-review.30223/). Hence the video makes a kind of more balanced impression for me instead of onesighted voodoadvertisement - something may not be necessary (I´ve not enough knowledge of it), but a harsh "everything nonsense" sounds kind of imbalanced to me, as there are no further arguments. Ah and there is no need for 2.850€, he mentions also cheaper options: https://audio-freak.de/marken-empfehlungen/ifi-active-power-conditioner-netzleiste/ (749€), combined with dc blocker (149€).
Sadly, yes..
Sorry, just no. If you shill for an audiophile fuse, you lost the plot...
A broken clock is also right twice a day.
That's a totally different product, it doesn't even do the same thing, certainly not filtering from 800 Hz on. He also claims all kinds of nonsense improvements:

I agree those conditioners are a waste. We're in the lightning capitol of the world so I use a Cyberpower sine wave UPS and optical USB cable to a powered hub plugged into it. As good as it gets for a silent noise floor. I even tried a Gustard U18 one time and it didn't help any.
