@raysmtb1 you don't think NASA ran tests several times before liftoff?
Why HiFi Gear Measurements Are Misleading (yes ASR talking to you…)
About 25 years ago I was inside a large room with an A-frame ceiling and large skylights, during the Perseid Meteor Shower that happens every August. This one time was like no other, for two reasons: 1) There were large, red, fragmenting streaks multiple times a minute with illuminated smoke trails, and 2) I could hear them.
Yes, each meteor produced a sizzling sound, like the sound of a frying pan.
Amazed, I Googled this phenomena and found that many people reported hearing this same sizzling sound associated with meteors streaking across the sky. In response, scientists and astrophysicists said it was all in our heads. That, it was totally impossible. Why? Because of the distance between the meteor and the observer. Physics does not allow sound to travel fast enough to hear the sound at the same time that the meteor streaks across the sky. Case closed.
ASR would have agreed with this sound reasoning based in elementary science.
Fast forward a few decades. The scientists were wrong. Turns out, the sound was caused by radiation emitted by the meteors, traveling at the speed of light, and interacting with metallic objects near the observer, even if the observer is indoors. Producing a sizzling sound. This was actually recorded audibly by researchers along with the recording of the radiation. You can look this up easily and listen to the recordings.
Takeaway - trust your senses! Science doesn’t always measure the right things, in the right ways, to fully explain what we are sensing. Therefore your sensory input comes first. You can try to figure out the science later.
I’m not trying to start an argument or make people upset. Just sharing an experience that reinforces my personal way of thinking. Others of course are free to trust the science over their senses. I know this bothers some but I really couldn’t be bothered by that. The folks at ASR are smart people too.

@invalid absolutely, I’m sure that they ran tests. But burn in as I understand, it claims that things get better after hundreds of hours of usage of the circuit. If that holds true for audio electronics, why wouldn’t it hold true for any other kind of electronics? My point was that back then everything was analog and you would think that if it makes a difference in audio electronics that it would make some kind of a difference and all kind of electronics especially something as important as some thing like an Apollo mission. |
@raysmtb1 you don't think they tested all there electronics and mechanicals for hundreds of hours? |
@invalid i’m sure that everything was thoroughly tested, but I never heard the term burnt in until around 2020 when I got on this forum. I’ve been around, electricians my whole life, and I never heard them say that the lighting would look better after the wires burned in. I’ve heard the term used when speaking of a new clutch, motor or drag racing rear tires. Those all make sense, but electronics. I always thought once they were wired and tested they were complete. If something requires burning in to be at its best doesn’t that imply that it changes when voltage is applied multiplied by some amount of time? How do the cables know when to stop burning in? If they change after 100 hours of voltage is applied wouldn’t they continue to change?? at some point wouldn’t that mean that they would go beyond their ideal, sweet spot and start going bad? Or do they only go to the good and then burn on into infinite perfection? |
