Ivan - as people have said it can be a "touchy subject" but I'll wade in anyway, since I have just finished playing with all of my PC's!
I have, what I consider my best cable, on my amp. A DIY Furutech 10 awg cable
- why there, because as I upgraded the other cables I wanted to be able to easily hear any improvements
- plus - it gave me the most noticeable results
- plus the benefits were heard no matter what source played
I then had funds for other cable choices, so I next upgraded the power cable on my power conditioner to a DIY 12 awg DH Labs Power Plus, which powers only my source components
- why there, because when I upgraded the cables on the source components I was able to easily hear any improvements
- again - the benefits were heard no matter what source played
- however I did try it on the amp just to see how it would perform
- it performed as well as the Furutech 10 awg which was 5 times the price
- It's not built to the same "TANK-like" standards as the furutech is,
- but it performs like it! - I wish I'd found the DH Labs cables first!
Finally I upgraded my source PC to a DIY Furutech 15 awg screened cable
- another outstanding upgrade
- the differences were immediately noticeable and what a difference all the upgrades made!
- why back to Furutech? - well, it was previously on the power conditioner :-)
Now all PC upgrades are complete and the system sounds amazing.
Some source upgrades were incremental, but taking this approach allowed me to hear the differences each incremental upgrade made immediately.
During this process I read lots of info on PC's and the reason why PC's work is...
- even though the outlet voltage is constant at 120v...
- the current drawn from the outlet is as dynamic as the audio signal itself
- therefore you need great quality conductors in the mains cable to handle those dynamics
- just like you have good interconnects and speaker cables to handle audio dynamics
- in fact, interconnect, speaker and power cables in a system should all be of the same quality levels
- otherwise the benefits from money you spent on those good quality components/cables is not being realized
- and those that are of a lessor quality become the "weakest link" and
- drags the whole system performance down to that level.
Hope this helps and Good Luck
