Power cord length

I made all of my power cords to length with Furutech components. The cords to my mono blocks are different lengths and I cannot tell any difference. I was trying to cut down on cord clutter behind my racks

^this makes sense^

OK, "Just for clarification."

Most here seem to believe that keeping the (Speaker cabling), the same length makes sense. "Time alignment".

Me too.

Most us?

The reason to keep the speaker cords the same length has nothing to do with “Time Alignment”, and if it did there would be many HT systems that would suffer.

The reason to keep them the same length is because the current on the speaker side is higher, and any capacitance or inductance makes the cable a filter, and we do not want a different filter on the left than the right.

At least I think that would be “most of us”.

Interesting discussion. 

On a most practical side, 8', or ~2.5m is one of the most standard power cable length, so it is simply easier for a manufacturer to harmonize on the standard length than to have a large inventory of different lengths that won't make any difference in performance (unless you are designing a front end circuit for a very particular type of wireless communication - then an extra inch makes a difference).  Take it from a manufacturer who supplies power cables with our products (filters).

How do power cables have sound? 

@jeffstrick    Thank you.  Your first post is incorrect.  Your second post is entirely correct.  Power cables cannot have sound.  And in particular, changing the lengths cannot change the sound.  Even if you install 2 miles of power cable of suitable current carrying capacity.
