Power cord length?

Well I like long powercords. Most of my Pangea powercords are 4 meters.
The up side is Pangea powercords are relatively cheap.
The downside on long expensive cords is they then are twice as expensive.
As the other poster mentions.. too short is a real problem.
But for an expensive cord. Consider ALL the possible locations you might want to try it and have it be long enough for that experiment.(I highly recommend trying it all over the place, never know it might really shine in an unexpected location)
Also bulky powercords can be annoying if you do not have a way to lay them out. I arranged my stuff/Power conditioner so the cords have a flat lay. If they had to be all bunched up it would be Hell.

And depending on the cord, it may have no benefit to being longer.

make sure the length of the cord is at least the distance between the outlet and the component

After that, I don't think it matters

I owned the most expensive MIT powercables. These days I know they are not the best anymore. The make instruments and voices too big in proportion. And yes longer powercables often sound better than shorter ones.

5ft is the optimum length.

What is the opinion of those here on this thread?, Regarding the question, what is the sound difference between a 3ft, 5ft, 6ft, power cord?, Is it the presatation?, meaning, forward presatation-A,B,C, seating role from the stage of a musical event?, sound stage seating of H,I,L seating role from the stage of the musical event, which I prefer, sounds more believable, Does these specific Lenghths change the tone?, Will one lenghth give listener fatigue over the next lenghth?, answer the differences period you can hear between 3ft, 5ft, 6ft, power cords to the best of your knowledge, I look forward to the answers, cheers.
