Ideal power cord lengths?

@curtdr

Welcome to the world of high end audio. Many of us started with highly skeptical thoughts on effects of various components. Then pretty quickly ran into objective reality… it doesn’t conform to logical thought. Power cords, interconnects, cables make small to huge differences. I was a practicing scientist when I first got into high end audio and quickly learned to listening to determine what made a difference and what didn’t. Hint, it all does.

My $17K to $22K Audio Research products ship with heavy duty 20 amp power cords. Replacing with a number of good quality power cords made large improvements in the sound. I spent nearly a year finding the best, and it was worth the effort. My system sounds significantly (and cost effectively) better.

@ghdprentice Well said.  You’re a good example of someone benefitting from keeping an open mind and letting your ears being the final arbiter versus just sticking head in sand and calling it a day.  Ignorance is bliss, to each his/her own, etc.

Early in your journey, when you are stretching just to get into what may be barely considered “HiFi”, speaking from my own experience at least, your mindset is just on obtaining the gear you can barely afford. The last thing you want to hear is that you should allocate a portion of your budget for cabling, including power cords..  It’s far more convenient to believe it’s ridiculous that power cords have an effect, and it IS a ridiculous concept.

I believe this is partly what has driven people to be so passionate about this debate for so many years, using the same common-sense based arguments that don’t apply, and passionately doubling down while refusing to find out for themselves by doing a simple blind test in their local HiFi shop. It’s far more convenient, budget wise, to believe that aftermarket cords make no difference. Very few people won’t hear an improvement with premium cords in a blind test when they actually get to doing it, and you absolutely don’t need to be an audiophile to hear the difference (my wife and daughter hear obvious differences but couldn’t care less).

etc.

Thanks for the welcome, but it’s misplaced.  It's far from early in my journey... But thank you anyway.

Yes, indeed, ears as arbiter I understand very well.

I also understand confirmation bias.

But if spending even more money on a 20k product for a power cord is necessary for you to hear "large improvements"... well, er, then I’d call out the manufacturer on that one because the amp must have some design flaw, because with a good enough amp there’s no such thing as "large improvements" except for system synergy with speakers, maybe dac, maybe... subtle, perhaps audible or perhaps psychological, improvements perhaps... One hopes to hear "large improvements" when one drops $500 or $1000 or more on a power cord or an interconnect, and hope leads to belief leads to thoughts of even greater nirvana if only, if only...

And I also understand priorities, to each his own there, financially and otherwise.

But as an educator, and as an educated long-time audiophile on the side, I do not agree that ignorance is bliss... and I’m also aware of endless, self-imposed rabbit holes that intertwist and eventually lead to more rabbit holes and never a home. So, if that’s where people want to lead the OP down, and if the OP chooses to follow, well then that’s your priorities and the OP’s priorities.

In my considered and experienced opinion, if you’re not satisfied with the sound of your system, and if you have a well-designed modern amp, you’re better off trying different speakers that are more to your taste than dumping money into cords and interconnects.

So, yes, follow your bliss, and if that means pouring money into... cords... well, so be it. Myself, I’m not following into that questionable hole, however, and the OP will just have to weigh everything out and decide for him or her self.
