Where to put your best power cable?

This reminds me of this conversation: 

There is no pattern, it depends on many things.

I used to have my best pc on power amp but now it is connected to the power distributor. And that after swapping pc's in the system. 

You have to experiment and be patient.

Do both ASAP!!

Those who I trust emphatically say source first. Of course, when I finally jumped into the higher ended power cord fray, ta da, I got them for my mono amps first. Then preamp, then sources. The exact opposite of what is recommended…..so….don’t listen to me 😁

Several posts above state "where the PC makes the most difference" - which is the best approach

This can be the source or the main amp

• many amps tend to have a heavy duty transformer/power supply, so adding a good power cables may not make too much difference
  • the better the power supply then a significantly better power cables will be required in order to hear a difference
• many sources have a crappy litle power supply, so adding a good power cdables will improve things significantly
  • in this case a lower quality power cables will make a noticeable improvement
• and of course the reverse may also be true

So figure out the quality of the power supplies in your gear and make an educated assessment

Take a look at Zavfino power cables, they are extremely good
