Who believes - that there is a minimum length for power cords?

  • To some people, what they believe, is the truth.

    Is there a minimum length for powercords to sound good?

    You just believe or you have actually tried?

    Please share your actual experiences.

     :D

  • The belief is based on EMI disappearance over the certain distance,  as far as I know.
    So the question of sound quality improvement is depended on whether you believe in lowering EMI level.
    I try very hard to keep length of my PC to be minium of 1.5m. Does it improve the sound quality?
    Nope, my system never sounded good.

  • Ever tried making powercords of different lengths to try on a particular audio component to test your beliefs?

  • I?m sure it depends on the characteristics of the power cord in question; manufacturers would design their cables to a specific (LCR) spec at a particular length, so it makes sense they?d tout that particular length, but most Audiophiles just swallow the manufactures marketing BS without really substantiating it themselves objectively.  :P

  • I believe a 240V current, will loose out its power, after travelling on a long distance.

  • I have done A/B with a 1.5m vs 2.0m power cord. Exactly the same model from same batch, just the length is different. The 2.0m cord sounded better. More relaxed, less forced presentation where the music flows better. The character of the cords remained the same for both lengths.

  • yes i too believe. 2m vs a 4m. it did sound different. so yes minimum 1.5m
    optimal sound would be 2m. there is no need to go longer.
    if funds permit, maybe just 1 particular equipment get a 4m power cord; for the source.

    your description of the possible sonic differences very similar to mine.
    in particular, the longer cord being more "relaxed", and music flows better.
    my comparisons were on a 0.7m and a 2m cords

    but.....

    i won't reveal too much yet

  • Minimal length from where to where? Wall to distributor, distributor to equipment or wall to equipment? How about from the ELCB to equipment? Is it measureable?

  • anywhere from wall/distributer to equipment. This is the final key part which most hear and feel the difference.
    technical terms would be we are changing the electrical properties of the AC power going into your equipment.

  • we are not merely changing the electrical properties of the powercord cable.
    we may also have changed the stress/tension factor being imposed on the cable upon setup.

    So it's basically " I said but he said"....
