Power Cable Break In - Such a Change!

Whether you know it or not, when you spend thousands of dollars on a power cord you have just entered the land of confirmation bias-- and there is far more actual peer-reviewed science to support that than there is, by miles, that supports the pseudo-scientific theories put forth by certain cable mfg’s.

Also, the poster that said that they have to charge what are essentially insane levels of price markup because, due to the stupid price, not so many people will want to buy them-- well gee, given you have all of that profit headroom why not lower the price way down and sell so many more of them? Why? Because, psychologically speaking, the price is a part of the sound.

I’d bet that no-one on this thread could listen to and rank a series of power cables by price, in their own system, using A-B testing-- even over long listening sessions with all of those cables previously "broken in".

BTW-- why do you think those super expensive power cords don’t come "pre-broken-in"? Given they cost thousands and have obscene profit margins, and adding the burn-in cost to the final product would be trivial on a $4,000 power cable for example. not-to-mention  that wasting 150 hours or more on break-in adds inevitable wear to your cartridges, tubes, electronics, etc.? Why indeed.

Don’t get me wrong, quality cables are essential to a good high-end analog system and the wire, connectors, and build are all important-- but you can get all of that from any number of cheaper cables-- and you will never know the difference, or be able to rank them by sound quality as I stated above.

And anyone with a "golden ear" surely knows that trying to judge the effect of a high-end cable or component listening to a YouTube video would hopefully know better than that.

Is there any other hobby that makes more wildly unprovable claims than this one? Maybe that could be a topic?

      If the planet's innovators/inventors/scientists had paid heed to the ubiquitous bleating of the naysayer, from the dawn of humanity; we'd still be listening to conchs for entertainment.     Well: PERHAPS they'd have admitted one for each ear DOES create a stereo effect, but...

     Their church's credo should be, "Science?    We don't need no stinking Science!"

I put together two new power cords about a week ago using Furutech FP-S55N with FI-50 NCF and FP-S032N with FI-28(R). Going thru almost exactly the same nasty break in as you are experiencing with Audioquest. 
The minute I plugged the new power cord in the sound was incredible. Best I ever heard my system sound. Then 2 days in harsh, muffled, artificial, glare, boomy. Then there was no bass…gone…just harsh mids and highs. 
I stopped listening and just gave it a 3 days with the components on 24/7.
Thankfully about 110-120hrs in it’s coming around.  The delicate highs, clarity in mids and textured lively deep bass. I’m expecting it to settle around 200hr mark but continue to improve up to around 600hrs based on what I’m reading. 
Break in is real and this was worse than anything I have ever heard during the break in phase. 

audphile1,

I have also built many power cables. The best I made was using pure 10 gauge solid .9999 silver wire with the Furutech NCF fittings. I used oversized Teflon tubing and braided them similar to the Dragons. They sound very good, but alas not as good as the Dragons.
