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.



Wire doesn't change its properties over time! Also, electronic components have very high tolerances and don't change after 100 hours.  Break in claims never cease to amaze me. It's your hearing that is changing adjusting to the new sound. People can believe whatever they want though but, in my opinion, its complete nonsense!

There have been some very good posts on both sides of the question.

From this discussion, If I had not heard the difference before/after breakin I too might (maybe) have been convinced that cables do not break in. Afterall it’s just wire and insulation?

But this phenomenon is real to me, as I have experienced equipment and cabling break in too many times in my 50+ years in this hobby.

However, it does seem that AudioQuest cables are especially sensitive to break in. My Dragon power cords were also quite dramatically changed after break in.

BTW, my system is posted on my systems page.


"I just experienced cable break in again firsthand."

I suggest changing "experienced" to "perceived".

@ozzy I am with you on cable break in and WTS, I believe that our ears/brain adapting is also part of the process. Enjoy the music

Congratulations @ozzy 

I hope to someday get new PC’s, but first I’m saving for a better streamer.
