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.

Ideal power cord lengths?

My two monoblock amplifiers sound fantastic without power cords. That said, I did an AC mains tweak eliminating the power cord and wall plug from my two monoblock amps, by installing the female IEC C13 plug onto the direct line from the electrical panel into the male IEC inlet of the power amp. Previous power cords were 12'' long, 12AWG. The two direct lines to the monoblock amps are 10 AWG BX/AC cable. Ideal power cord lengths for my amps would be no power cord. Your lengths may vary! 😎

what truly counts are the end connection points , here purity copper with gold,silver or rhodium over the copper , with ,not brass which is bright and no where good of a conductor. 

I agree. One of the reasons I eliminated the power cords from my two monoblock amps was to eliminate two connection points, the wall plug and power cord male plug. Also, another reason is to negate the question to me about what power cord sounds best. Running my amps directly to the dedicated circuit sounds better, in my opinion, then running them with a power cord.  😎
