Cable Break In for the Naysayers


I still cannot believe that in this stage of Audio history there are still many who claim cable break in is imagined. They even go so far as claim it is our ears that break in to the new sound. Providing many studies in the way of scientific testing. Sigh...

I noticed such a recent discussion on the What’s Best Forum. So here is my response.

______________________________________________________________________________________________ I just experienced cable break in again firsthand. 10 Days ago, I bought a new set of the AudioQuest Thunderbird XLR 2M interconnects.

First impression, they sounded good, but then after about 30 hours of usage the music started sounding very closed in and with limited high frequencies. This continued until about 130 hours of music play time.

Then at this time, the cables started to open up and began to sound better and better each passing hour. I knew at the beginning they would come around because they sounded ok at first until the break in process started. But now they have way surpassed that original sound.

Now the soundstage has become huge with fantastic frequency extensions. Very pleased with the results. Scientifically I guess we can’t prove cable break in is real, but with good equipment, good ears, it is clearly a real event.

I remember the phase that "if we can’t measure it, it can’t be real".

However, perhaps we do not have the proper equipment to measure it.

we do…our ears. 

@tattooedtrackman great question/point!

I definitely noticed with some cables I purchased used, there’s about a 24hr and some time longer period that’s needed for the component/cable pairing to start to gel. This applies largely to power cords. Less so with interconnects and speaker cables. And I have not noticed this with Ethernet, USB and other types of digital cables - there is or isn’t any difference it will be apparent right out of the gate.

Nordost power cords are a case in point. I connected the cables, listened for an hour and came back to it next day to find it sounding completely different than when I left it. And yes there’s a getting used to new sound phase but that’s after this change has already occurred. There’s no denying a few days usually is what’s needed to start to get into the subtle differences with cables and components unless you jumped from a stock power cord to a top of the line big $ cabie or jumped from a Bluetooth dac to a $5,000 high end one. That’s been my experience.

@carlsbad2 can you please elaborate on what can possibly change in a vacuum tube throughout the course of the limited break in process you have come to accept as a phenomena?
And another question as you have a degree in physics…does a dielectric change at all in any way after the interaction with the electrons traveling on a surface of a copper wire? Is there a change at a molecular level in the dielectric or the surface of a wire or both?

I’m also trying to figure out what exactly goes thru the break in process in a Furutech Rhodium plated outlet that results in such a wild sonic rollercoaster?
I can’t explain it but would love to hear a scientific explanation. Or may be none exists. I may be going off the rails on a crazy train here because I can detect these changes…
