Power Cable - Burn in

I run the P10 and recently updated the power cable into it after having a test cable supplied to me as I was not sure the benefit since the power is converted - it made a difference.

My power is somewhat steady unless weather takes effect or 4 tons of AC kicks in, rare where I live, but it does happen and needed.

The main point I am writing about is not the debate of the benefits of the power cable, but what I noticed reading the screen of the PS Audio P10.

Upon hookup, the test cable measured around 117V coming in and the standard 120.5ish going out.

After a few hours it would climb to 118/119, then a few days of running all day it would come in at 120V.

I just put the replacement cable in and it’s following the same trend, starting off at 117V and climbed to 118/119 a couple of days later.

The manufacturer recommends 168 hours, and at the series I drifted to requires a supposed and staggering 336 hours.

In short, I am posting my observations and an older screen shot for those that are not aware of what the screen looks like.

I’m a fish guy, not an electrical engineer, but what I believe is occurring is the visible sign of cable burn in.

The audible aspect is not even debatable, I think it was MC Hammer in the 80’s or early 90’s that said something like, “you can’t touch this”, the system is sounding that good and not cause it’s mine.

If your voltage input is changing from day to day, I highly doubt it has anything to do with your cable burning in and everything to do with your power grid. I have never heard of a power cable not passing the voltage from the wall to whatever device it's attached to. If your PS Audio device is telling you the input voltage is 117v and you think it really is higher because the cable is clamping the voltage somehow, unplug the cable and measure the voltage at the wall outlet and see if it doesn't read 117v.

+1 on this,...unless your power cable has internal gadgetry to morph the signal, you are not seeing the result of cable burn-in,..you are seeing voltage fluctuation from the wall.
This said having had several power conditioners that showing input voltage, etc...and having burnt in a lot of cables over the years...
 
There are many, many overlooked uncontrolled variables that are much more likely to cause audible differences than power cord burn-in.

If a power cord causes line voltage to change over time (with a steady load) there is something very wrong with the cord and it should be replaced.
 
168 hours huh, not 165 or 170......

I have no measurements, but I have been noticing changes over time with all the PCs I recently put into my system.
