Why HiFi Gear Measurements Are Misleading (yes ASR talking to you…)

@fredrik222 , I think the logic of your argument is absolutely sound. Where I totally lose you, completely, is the notion that everything about commercial audio gear is 100% understood and therefore science can explain everything. Believing that we know everything about a topic like audio gear, in scientific and measurable terms, is what I can’t get behind. I get that you feel that this position is closed-minded, but it is thoroughly debatable as to who is closed minded in this scenario :).

There was a time when one popular theory was that human ears were not good enough to perceive the levels of jitter that exist in audio gear. I don’t even think ASR would support that belief at this point, and I think we are past that. As you stated, things evolve and so does our knowledge.

Evan @noske was taking the position that no scientist should ever take the position of believing they know everything to the extent that in their minds, it is “case closed”. Which is what your argument seems to imply - we know everything about commercial electronics so there is no need to believe we hear something that cannot be explained. Who is closed minded?

Would love for Amir to join in but totally understand and respect why he wouldn’t, considering the unnecessary nastiness going around!

We should strive to keep the discussion and debate positive and constructive.  We are discussing a subject we all care about whatever side of the fence we are on.  

Threads like this make me yearn for a much simpler time. Like many years ago when we had tone controls. Everyone’s looking for a way to tweak their system these days.  it was so much easier back in the day when you turn knob or push a slider.

while reading through all this, I had a couple questions that came to mind. Let’s say it’s 1969 and you are an astronaut sitting on top of a rocket ship heading for the moon. Do you think any of the astronauts asked Houston if they had completed the burn in of the electronics inside the capsule? You would think something that important if burn in was some thing they would’ve known about it back then. Does anyone know? Was it something back then?

@raysmtb1 you don't think NASA ran tests several times before liftoff?

@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?
