Cable Burn In


I'm new here and new to the audiophile world. I recently acquired what seems to be a really high end system that is about 15 years old. Love it. Starting to head down the audiophile rabbit hole I'm afraid.

But, I have to laugh (quietly) at some of what I'm learning and hearing about high fidelity.

The system has really nice cables throughout but I needed another set of RCA cables. I bit the bullet and bought what seems to be a good pair from World's Best Cables. I'm sure they're not the best you can get and don't look as beefy as the Transparent RCA cables that were also with this system. But, no sense bringing a nice system down to save $10 on a set of RCA cables, I guess.

Anyway, in a big white card on the front of the package there was this note: In big red letters "Attention!". Below that "Please Allow 175 hours of Burn-in Time for optimal performance."

I know I'm showing my ignorance but this struck me as funny. I could just see one audiophile showing off his new $15k system to another audiophile and saying "Well, I know it sounds like crap now but its just that my RCA cables aren't burned-in yet. Just come back in 7.29 days and it will sound awesome."

 If only we could be so fortunate! I'd like to say ignore him and he'll go away, but he won't… 
And yes, there is no point in debating with him, he just keeps moving the goalposts.

"When someone recently stated that there have been many blind tests of cables, I asked him to provide links to blind tests. Which someone did. That’s an example of asking for evidence of a bold statement. "

And then you dismissed blind tests. That’s my point. Reading over this and a few other threads it typically goes like this:

1. Someone makes a statement you disagree with.
2. In your reply you ask for evidence. And usually throw in some pretentious and snarky dig at them....presumably because they had the nerve to believe something that you don’t.
3. If they produce evidence, which many people won’t because with you there is no point, you then dismiss the evidence out of hand whether it be subjective, measured or blind tested. And usually throw in another patronizing dig questioning their intelligence.
4. If someone has the nerve to point out this pattern you resort to direct ad hominem attacks and in this case, dismiss the rest of the thread as a veiled threat that you won’t grace us with your presence any longer.

>>>>If you can’t stand the heat get out of the kitchen. Tip: If I were you I’d lose the attitude pronto. At least you’ve apparently learned the difference between evidence and proof. But we’ll see....

There needs to be an ignore option here like the Tapeheads site for people who make a forum post flow and read like you're walking through glue trying to carry a big Krell amp. Are you listening Audiogon??????
I have been a cable tester for about 15 years for a small manufacturer.  I've heard maybe 100 different cables, most never making it into production.  Before I test them, I burn them in for 24 hours, minimum.  I have found that a new pair of ICs versus a 24 hour used pair of ICs can sound very, very different.  

I've also tested Monster Cable 300s series years ago and found no appreciable difference after 100 hours burn in.  I found a slight difference using Belden low capacitance ICs.  Then again, I found that High Fidelity brand cables sound terrible on any system I've heard, generally, very expensive systems of $300,000 to $1 million.  I'd rather listen to Monster 300s than High Fidelity cables for musical enjoyment.

Since comparing newly manufactured audiophile cables to burned in cables is so obvious to me as well as to others, may I suggest that some or many professional based balanced cables do not have a significant burn in change in sound.  Note that so many great recordings were made using cheap professional cabling back in the 50s to 70s.  Could they have been better with more advanced design and metallurgy cabling?  I don't know.

When I purchased my SME IV arm in 1989, the dealer said listen for a while, then bring it back for modifications.  He shot closed cell insulation in the arm to remove the low mid/upper bass hump and installed Cardas phono cable with an RCA junction box.  It took about a month (100 hours) until I found great enjoyment using my new arm.  I am still using this arm in 2018.
