Better Audio by Solid State Amps after Coaching of certainly Electrolytic Caps ??

I discover this website from Ukrain - the motherland from Vitali and Wladimir Klitschko:

and the translation with loss informations:

Here's called this step "Electro training" instead coaching. About this I have never heard before.
The electrolytic capacitor is DC biased, additional a ripple current burden with help an AC voltage of different frequencies.
Basicly this is a AC coupled power amplifier with a 2 ohms dummy load instead the loudspeaker.

What happens in real world ?

Ukrain

right would be "Ukraine".

About this I have never heard before.

it is not surprising.

Coaching electrolytic capacitor in low current devices such as DACs, phonos preams, preamps etc is not efficient, much more efficient would be training electrolitics in a such device with high current and white noise(or in range 50-30000Hz) before soldering to PCB, sonically the difference is very big between electrolityc before and after electro training.

For high current circuits such as PSU of output stage power amplifier there is no need to training electrolytics before soldering to PCB.

can one really different look the capacitors for power supply and that one for signal requirenets if there are high currents?
Have a look to schematics from post #13 about
http://www.diyaudio.com/forums/pass-labs/160416-threshold-amps-dc-protected.html
in this case

tiefbassuebertr sorry i dont understand what is you question.
All signal currents flow via output capacitors from such floating PSU design and the is no need to coach them before soldering

At first look this is for me the same than that, where all signal currents flow via the output capacitors from floating PSU design. Obviously not for you. And this is, that I don't understand.

For high current circuits such as PSU of output stage power amplifier there is no need to training electrolytics before soldering to PCB. training can be done when cap is soldered to PCB with white noise generator

Translated into English this is probably about break-in of electrolytic caps. You have never heard this before?
