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 heard it with my own ears is the least believable response that one could give.
The human brain is very dynamic and is the most reasonable explanation to why it’s not cable burn in, but brain adaptation.

Electron flow doesn’t change in cables after time and no one has ever given a truly scientific explanation on what could possibly happen to create an audible difference
in the molecular structure that could be attributed to people’s claims.

I’ve done analysis of ultra-high speed cables used in super computer interconnects and never did we have to worry about metallic cables changing properties after use. Electro-migration in semi-conductors is a real phenomenon, but we’re dealing with tiny areas of metallization where a difference of a small percentage of material can have a real world effect.

Yeah, you can believe the true Audiophiles who actually listen to music not measurements.

Earbuds probably measure pretty well too.
