Cable burn in

I have a few Morrow cables and the longest it took for burn-in was 367 hours and 10 minutes. Once the cables are "burned" everything changes...food tastes better, colors are brighter, people are suddenly gathered on the street to hear a bit of my rig if I open the front door or something...plants grow faster...and I am comforted in knowing I'm now a somewhat better person in all ways.

I put my cables in the oven to burn them in. Slow cooking, 3 hours at 90 degrees C, turns out to give the best results. Amazing sound stage, deep lows and warm yet crisp highs. Sounds even better with my eyes closed and after 2 glasses of wine.

OK, pun intended. But if such a thing as ’burn in’ of cables really exists (meaning the chemical / mechanical properties change in the first hours of usage, influencing the electrical properties), then the probability of the sound getting worse is as high as that of the sound getting better. 50/50 ... the OP apparently fell in the ’it got worse’ 50%.

JasonBourne52 I see you're still as dumb as a fence post if you think that wires don't make a difference in sound different and obviously the equipment you have is not very good LOL quit spewing lies to people you have no idea what you're talking about.

Nordost article on cable burn in:

I found what they write on potential electrical effects of cable burn-in not overly convincing. Graduate degree in automation of physics experiments, and consequent experience of working in two national labs, makes me skeptical toward such claims. What I heard from a music college professor is easier for me to believe.

The professor attended a cable presentation at his local audio show. The rep giving the presentation was swapping the cables from generic to expensive to more expensive to very expensive to outrageously expensive. Each time, the sound quality of the same fragment of music noticeably improved.

Little did the rep know that the professor was covertly using a sound volume meter. Each time the rep swapped a cable, somehow, volume went up about 2db. Apparently, simultaneously with swapping the cable, the rep was slightly nudging up the volume control.

Duped once by such a trick, a person may then honestly believe that cables make a big difference, and such prior conditioning helps finding such differences later on. I'd recommend buying a sound volume meter, and matching the output to at least half a decibel at a fixed frequency, let's say 1 KHz, before making any comparisons.

Youtube has plenty of suitable test signals.

Mogami is high quality cable, in one word transparent the way any cable should be. Its use in many professional recording and broadcast studios speaks to the quality. These are environments where the BS and sales hype of overpriced cables have no influence, only sound and material quality that gets the job done matters. Anything more is fluff marketed at those with more money and ego than practical wisdom and common sense, like most here.
