Ideal power cord lengths?


A quick Google search suggests there is consensus that the ideal power cord length is 2m.  1m cords sound “harsher” and 3m cords sound “smoother”, with 2m being the sweet spot.  The PS Audio dude suggests that the reason is that the reason is that all cords have an impact on the power, and the greater the length, the greater the impact, good or bad.

I know many will say there is no difference between a 1m cord and a 3m cord.  But my question is, who here has tried like model power cords of different lengths, and what were the differences?  
 

Second question:  How does length factor into the equation when you have a cord feeding a conditioner, then other cords feeding components?  If 2m cords are in fact the ideal, would 1m cords be ideal when using conditioners?

I tend to believe those that say that power cord lengths matter.  While I’ve not been able to do this test myself, I’ve had these two experiences:

  • Testing Audioquest Diamond and Nordost Valhalla 2 USB cables, the cables shorter than 1.5m sounded TERRIBLE by comparison.  Especially the .75m Audioquest Diamond vs the 1.5m version.  But the 1m Valhalla 2 also sounded awful in comparison to the 2m version.  In general this opened my eyes to how much cable length matters, and counterintuitively in the case of digital cables. 
  • I have a 2019 2m AudioQuest Hurricane Source cable from back when AQ braided their cables, and I also have the newer non-braided Hurricane Source, but 3m in length.  The new Hurricane sounds vastly superior to my old 2m Hurricane.  In comparison the older cord compresses the soundstage depth.  I don’t know if the differences are due to the differences in length, or if it’s due to a design change by Audioquest.

Very interested in learning of others experiences with power cord lengths.

Power cables need capacitance…Long ones have more.

you can even measure that!

shunyata ideal length is 1.75M.

voodoo 2meters

wireworld 3 M

you see they all vary

 

3m is too long. In my book, the sweet spot is between 1.5m to 2.0m which is about 5 to 6 ft. Both Wireworld PCs which I own are 1.5m in length.

I find the two meter sounds better than one (or shorter). This makes me think of the length of wire from breaker box to room receptacles. And of course the type of wire.

I believe we are limited by practicality. 

The late Bob Crump determined in his extensive tests, that 7.5 feet was optimum and any lengths longer would not give any more sound signature of the given cable. Of course he did not test 100 cable brands, nor has anyone else. It would take too long and cost too much.

I have found with shorter than 1 meter cords, the Belden 12 AWG ( or generic similar) with a better IEC connector, sounds very good, and better than some custom cords. For longer than one meter, choose an Audiophile power cord. 

@1971gto455ho Could you post some pictures of your system? Im thinking about making some changes to my mine and am curious about all that you’ve got going on there, thanks in advance. “Pony” panel especially,Ive never even heard of that before.

@bikeboy52 

Will be posting pictures shortly, we’re down to minor drywall and paint. As usual will do it in a month turned into six…lol. Overall I’m happy with what’s been done. PM me if you want a little info 

Cheers

I have  a transformer right outside my window and dedicated circuits to my music room. Mono amps share one furutech outlet and the other gear is on a Furman it ref 20 I,  it's plugged into a wattgate 381 AU evo clear outlet.  This outlet shares the lights and two other outlets but I keep the light out and nothing else on those other outlets.
All  12 awg I installed myself through the whole house when I built it.

I made the mistake of building some one meter pc's and there two short for right now so I have two meter analysis plus ovals, I don't know why someone would pay 2600 for them, I damn sure didn't, I bought them used and put some furutech ends on one of them.
I have some pretty clean power but will do better one day. If you plan on using furutech dps 4.1 better make them 1.5 meter.
