What are we listening for during break in?


Is it time for a reality check? A few days ago a post was started which asked a question concerning burn in of interconnect cables. The consensus of answers agreed that this was a necessary function with no opposing view. The recommendation that got me thinking was to install the ICs between cd player and preamp and use a test disc for 250 hours. My immediate reaction to that bit of advice was "give me a break." That is roughly equal to listening to 250 cds. Considering the amount of time I spend listening to music, it would take me six months to break in ICs.
I have experienced a sonic change after new speaker break in period so I'm not argueing break in doesn't occur. Whether a sonic difference occurs after ICs break in is another matter.
My question is, what are we listening for when we run our equipment for 250 hours just to break in an IC or modification? I don't mean why listen to music, I mean what sonic difference are we hearing? Is it better, worse, different, What the?

Wow, how can any audiophile who has gone through much wire say it needs no break in. Come on folks this is audio 101, audio grade school if you will. Of coarse they do. Some more than others. They all react differently. My current set sounded closed in and compressed for 48 hours. After 72 they are great. No big deal, just let if play softly 24/7 until the changes stop.

This is one point that is an absolute fact - cables do require break in. I dont mean to be "emotional" but I have not read statements this much away from he truth. We can all have preferences for one cable vs another etc... But, to say cables dont change with a little burn in time is 100% false. In fact, if you just ship one to a new buyer it takes a couple of hours for the wire to settle into the new system.

Ok, I had to let it out. Sorry if I came accross strong. Well, maybe not :-)
Some have suggested it is the listener who is becoming adjusted to the new sound and not the cable being broken in.

Start listening right away. Then the new sound will replace the old sound as your standard.
Gregadd, no it's not the listener. We are talking about objective not subjective changes that are easily heard. A/B two wires - one new and your current IC that you are familiar with. At first the new wire is not as deep in the bass as your current wire. The new wire is a little bright and the stage is small. Your thinking, hey I wasted my money. Over time the new cable breaks in and you decide to throw the old one back in to do another A/B. It is obvious the new wire has deeper bass and a larger stage etc.... This is not listener break-in.

This was my most current experience as an FYI. If you submit it is my mind playing tricks again, then we should all buy an old JC Penny MCS series stereo and settle into it as it will soon sound like a CJ set-up in my mind. Fact is why waste anytime with any gear as our minds call the shots and we are to fickled to make accurate determinations.

I think most people can detect differences and trust they are not fooling themselves with their own gear, in their own room over a long period of time. This is the way to know.

Over time your mind is not tricked as all of your mood swings, attitudes, stress levels, neighborhood power demands etc have been accounted for and you know the truth.

At least I do :-)
Grannyring, you are passionate in your belief. As I've never experienced it, I have a hard time understanding and therefore believing a wire changes its sonic characteristics with a hundred hours or so of use. If it does change after break in, does it always change for the better or have you ever heard one get worse? If they always improve there must be some reason, why would that be?
As stated in original post, I have experienced sonic changes in new speakers after break in. It wasn't subtle. I also believe not all components sound alike and I have heard a difference between speaker cables. Maybe I don't listen close enough to new cables to notice a change. In fact I know I don't listen close enough as I'm not sure what I'm listening for.
Point one- I have long since abandoned A/B testing thanks to the late great Harvey Rosenberg. I tend to know what I want when I hear it. I keep it till I tire of it,it wears out or becomes obsolete.

I assume everyone has a reference that is the sound of thier own system. Some claim thier reference is live music but they are usually deluding themselves. When you install a new component you have to form a new standard.

I have yet to hear any credible explanation of what part of the cable is being burned in. This differs from moving parts, tube or caps,etc. Maybe a power cord generates enough power to burn in. Not interconnects or phono cables. Monster amps get hot but that heat never seems to make it to the speaker cable.

I have no way of disputing what you heard. It certainly differs from my experience. No harm comes from burning in a wire unless you purchase a burn in cd. In case you will be out whatever you paid. Everyone should have some type of frequency spectrum cd or lp to assist you in spea ker placement. That will do just fine.

You may have deduced I am a cable skeptic. I'm definitely fro
