It’s kind of a moot question since placing a Shun Mook Original Cable Jacket around whatever length cable improves the sound. Ditto the Highwire Power Cord Wrap. Plus you be got your wall outlet and wall outlet cover to worry about, and contact enhancers. Oh, my!
Power Cord Length
Here's one for the electric wizards to kick around. Whilst attending Axpona this weekend I was doing some power cord shopping. At one particular display I was being told by a very well known cable company representative, I'll not mention the name so it doesn't influence any responses, that the rule of thumb is that in order for the pwr cord to be effective it needs to be at least five feet long. This allows the current to be in the cord long enough for it to be effective. Ok, I'm really dumb when it comes to this sort of thing so maybe I said that in the most simpliest of words but that's pretty much how it was explained. Anyone care to elaborate on this good or bad?

Really? That’s why? That was your reason? Huh?

Food for though. For those that believe most of the EMI/RFI noise generated in the ac power feeding the power supplies of audio equipment is actually generated from the associated audio equipment of the audio system equipment consider this. IF you believe that two dedicated branch circuit is better than one to decouple the power supply’s of a CDP from an amplifier, there by preventing the digital hash from the CDP going back out on the power cord and then reentering the power cord of the amplifier, then why is it so hard to understand that a power cord couldn’t be designed to help do the same thing? What IF you have a CDP and an integrated amplifier plugged into the same wall duplex receptacle using the OEM power cords that came with the equipment. Will the two power supplies of the CDP and amp be more likely coupled together than they would if they were fed from two dedicated branch circuits? What IF a well designed power cord can reject the digital hash, (call it what you want, RFI, harmonics, high frequencies, what ever), from going back out on the CDP power cord to the duplex receptacle and then reentering the power cord of the amp’s power supply. Would that be a good thing? So, IF you believe such a power cord can be designed and built which do you think could accomplish the task better, a power cord that is 2ft in length or one that is 5ft in length? |
If the power cord performs some type of filtering than probably the longer the better. If the cord is to transfer current like for a Amplifier or a power conditioner than a heavier gauge shorter wire would be best. But in reality, I have used quality power cords that are a few feet long and some that are 5 meters long. If they are properly designed for the task there should be no problem with sound quality. |
Ok, so keeping with what usually happens here (which is what made me go away for so long) my simple question which was directed to those that actually knew something about electricity ended up being answered mostly by guesses, personal opinions, advice on how to buy cords and another debate as to wether aftermarket cords and cables are better then the stock cords. I don't remeber asking for any of that. I just thought somebody could explain why this company rep said what he said, other then to just make you spend more money on a longer cord. So you can all sleep easier tonight, the company was Nordost. Also, as long as it was started up again, anyone that doesn't believe that cords and cables don't make a difference, get a different hobby. For those of you that tried to give an answer with some merit, I thank you.. |
Just as well you didn’t mention their name. Quote from their site:
The minimum recommended lengths of Nordost cables are as follows: End of quote. Why? Because they say so, that’s why! I could not find any white papers backing up their claims. At least Shunyata takes the time to explain the theories behind their claims as well as actually tests. Pictures and graphs too! |
