I have never seen wire measurements change in an interconnect in a normal use. I have done those tests, like many others, years ago. It is not new to me. I have been at electronics for a long time. I thought I read the post, whether you call it warm up or not, after two hours at a meal it sounded so much better. If I got it wrong then sorry.
No problem, tomelex. Too many posts to read, too little time.
Now with all due respect, should anybody really care that you’ve never
seen wire measurements change in an IC? I sure don’t. That’s kinda’ the topic of this thread, isn’t it?
The question is, have you
heard a difference occur in an IC over the course of use? I have perhaps 25 – 30 times or essentially any time I’ve acquired a new set of IC’s to audition. And if I wanted to guarantee I hear an improvement at burn-in, I only need to send my IC’s out for cryo-treatment which essentially returns the materials / properties back to a state of unused or like as new. After install and round-the-clock playtime at a certain time allotment (almost like clockwork), they will achieve a fully burned in state that is evident by a sonic improvement almost like a light switch being turned on.
That’s just with IC’s but the same is true with essentially every other electrical part or component. Not only is the phenomena entirely repeatable, but I can also predict the approximate time required to reach full burn-in status. The simpler and smaller the part, the more accurate I can predict the time required to achieve full burn-in status. For example, wall plugs, outlets, IEC connectors and inlets, fuses, etc, the required time is roughly 53 hours plus or minus 30 minutes. IC’s of 1M length generally 5 ½ days of continuous burn-in.
Now many claim to have experienced the benefits of this “burn-in” phenomena but at the same time many have not. And depending on the product and if proper or superior cryo-treating is involved, the potential sonic improvements are most always anything but subtle.
But I’ve yet to hear of a single story where somebody attempted to measure these sonic differences. Perhaps it’s because those who possess sensitive measuring instruments don’t believe in “burn-in” so they won’t trouble themselves any further?
Of course there can be a time period for devices to stabilize, some more than others. Question is audability not some panzy wanny hyper technical theoretical super minute measuremets that confirm a change took place, but an audible change, ' interconnect Wires, no. fuses, no they get worse with heavy use, not better. speakers need to be broken in, they are mechanical devices after all. tubes change all the time.
Can be a time period for devices to stabilize? My passion is extreme forms of vibration control. For 15 years my fabulous performing Foundation Research line conditioners (LC’s) always sat on the carpet behind my system. About a year ago, I decided to see what I might be able to do to improve their sonics by applying a similar methodology that I apply to my other components, to these smallish passive LC’s that have very few internal parts.
What I fabricated was just a make-shift apparatus out of spare parts and though this apparatus somewhat follows my methodologies, the materials and construction was certainly inferior. Nevertheless, over the next few months I received no less than 35 – 40 distinct audible improvements from those line conditioners.
Considering these LC’s have no power supplies of their own (no internally-generated vibrations) with few internal parts and the execution was certainly inferior, I must admit I was rather surprised how receptive they were to my method of vibration control. Such audible improvements were derived solely from my attempts to control the mechanical vibrations at the LC’s. Considering these LC’s are 7 years old and well burned in, there should have been no opportunity remaining for electrical burn-in to have this effect.
Ears/brain interface change or adapt all the time. yes, and they are hardly calibrated and easily fooled by inputs from the eyes etc.
Sure. But again please don't say the eye/brain and brain/brain combo’s are more reliable. I’m unsure why people keep bringing this up as though it has any real significance for anything. It should go without saying. But it never does. I can only surmise that the eye is more easily
trained than the ear.
Burn in is different than mechanical changes. Burn in is mostly electronics, not interconnect wires. Speaker wires can change when driven hard, and so can speaker coils, but that is not anything new.
Actually, you are incorrect. I can demonstrate that not only does electrical energy behave exactly like mechanical energy, at least when pertaining to audio, I can also demonstrate that electrical burn-in times are near identical to mechanical settling in times. And really that should be no surprise to anyone since electrical energy is just variation of mechanical energy. As is perhaps all energy and all matter.
In fact, at this juncture I’m pretty much convinced there is no such thing as an electrical “burn-in” process. It’s really just a variation of another mechanical settling in process. The fact that wire vibrates when current passes through it may substantiate my hypothesis. The only difference I can tell is that electrical “burn-in” has a memory whereas mechanical settling in has no such thing.
