pcb tracing

[POTL]

Hello everyone, a question of a beginner
So it is necessary to bring to each component a separate power line (in the figure below from the main line, each component has its own line)

In the second figure there is one line on which all components are connected, that is, the current passes through 1 of the component's legs and then goes to the next

Are there any differences in sound and noise or there is no difference?

Nobody knows?

Each method works.

Hi, I'm aware, the question is, how much better in terms of signal and noise.
If, as in the second picture, will not the voltage be lost and the noise from the components increase, will the effect of the cascades be on each other in this situation?

On stuff only a few inches across, no HUGE currents, it makes no difference.

Audio POWER amplifiers can be fussy. We are far far away from those conditions.

Another way to think: I want to plug in 5 stage-amplifiers. Do I bring one cord from the wall to a 5-way box? Or bring 5 cords from the wall? Assuming the cords are substantial, and there's no kilo-Watt bass amp involved, it makes no difference. In small audio, the smallest PCB trace is "substantial" for the small currents involved.

It mostly comes to layout. On strip-board it is natural to pick one strip for power. In PCB work you tend to cluster signal parts near the chips, and run power anywhere you can.

thanks for the answer
I've always worked with breadboard boards, I've been breeding different pcbs on a computer for the last half of the year, and I always tried to do it as in the first picture, but at some point I remembered that on the circuit boards there is one power path and all the details are connected, I will build boards as on a printed circuit board, then the noise from the components can be amplified and transmitted to subsequent cascades.
But if there is no difference in the pedals, then I can be calm =)
