Power cable from wall socket to power strip

Trial and error seems to the way I usually evaluate changes I make within my systems, along with a lengthy audition.

@simna-

     I found so many different and contradictory answers and opinions so I wrote these questions that made some here mad at me.
                                        I’m sorry for that.

                                         You opened the thread with:

               I don’t want a discussion with ”non believers”.

                              Let the Cargo Cult go build another runway!

                                                    Who cares?

                                                 Happy listening!

mihorn answers made it clear to me that testing is the only way to find out what works best for one and each.

How do we know which one works better? It is simple. The better one (power cord, any audio cable,  and any component) sounds closer to the original music. The original music is cleanest, smoothest, and the most musical. Alex/Wavetouch

I figure the best way is to borrow some high end power cords and compare them with an ordinary power cord.

@simna

yes, Yes , YES!! The best solution is to try yourself in your own system using your own ears. Only you can determine if the sonic change if any is worth the price within your budget. While you’re at it, if you get a demo power cable, you may want to try on your other components also.
Some cable companies allow free trial, or you can buy and sell used to save $.

The power out of the wall is commonly very noisy from other appliances, grid sharing, etc. Generally, a “quality” power conditioner usually has significant positive results (lowers noise), but a very small few with likely an extremely revealing transparent system, the conditioner may subtract a positive sonic trait. But it seems most report significant positive changes.  Dropping the noise floor allows one to hear more into the music.
