Power Cord Length

Mr Czaray to say stock power cords do as good of job,fine,sound the same,what ya smokin' son.Not only are you wrong,(new hearing aid batterys needed) but they can improve the sound of most every piece.cd likes small gauge,most others sound better with larger gauge.Silver coated helps most power cord wire sound better on every piece.Go buy a 2000.00 power cord,plug it in and rethink every theory you ever had.sorry to be so blunt.    psst pass it over

Hi
I have tried many cords and have only emperic knowledge regarding their influence on the sound. My experience is that the better your gear is, the greater the effect on different powercords ( or anything else ) is.I can easily hear the difference between a 2 mtr or a 4 mtr cord. ( Used fromt the wall to the powerconditioner )Why it is so, well i cannot tell and i really dont care as i dont have to design it. Trying to explain it with a theory or so called common sence, will only distrac me. I try things out. It takes time but its the only way to get the knowledge, as there always are so many factors you cannot predict.Happy lisining

Not my intention to negatively reflect any thoughts or ideas here; let me say that cables DO make a difference and I have spent much time and money finding the ones that work best for me.

Yes, happy listening!

I love how people who have never tried "fancy" AC Cords are so sure they cannot make an audible difference. I hate that they do indeed make quite a difference in most cases but they are terribly synergistic and it is difficult to recommend any one overall. Just the stiffness of the local electrical grid can be quite a factor as well as the associated equipment (and appliances) on the same lines. Damned if the ac outlets themselves seem to affect sound too.
 One poster is right on the money. They are indeed a parasitic element to the power supply. They can be designed as filters (or include filter networks), used for current or voltage storage and at least one claims negative impedance while others claim shielding makes the difference. Then there are those who claim they act as a transmission line so the geometry and dielectric matter there. Different metals, conductor shapes, and terminations also seem to have their own effect. Resonances (all finite length conductors have) based on length and propagation speed can be seen with an oscilloscope and frequency sweeps or a network analyzer. There are mechanical vibration and microphonics to deal with; even static charges are dealt with in some cases. Wire loss or DC resistance is a fact in any case and varies with frequency.
 Regardless of explanation or principals whether or not it is audible to you should be the criteria. We just do not know it all and our system of measurements are quite limited and lacking IMHO. Find a friend and try some blind testing if you can. Mixing and matching is part of the art.
 It must also be said that many designers are not going to give away their particular paradigm or trade secret while others do have white papers and measurements galore it is a complex issue. Ultimately it is your own listening judgement and I urge you to try experimenting. The  relatively inexpensive DH Labs bulk DIY cable is a great place to start.

WOW! I will now return to the ADULT world, goodbye

Don't let the door hit ya where the Good Lord split ya!!
