John: An abbreviated summary of part of this thread:
(bold is my highlighting, italics are my added comments)Peter: Define accuracy
Soundmind: "If what you mean by not having a sound is that they do not alter the signal to the point that there are audible changes then we ARE speaking the same language. That is what I have defined as accurate." Can't argue with that
"What does this mean in practical terms? Frequency response flat within audible limits. Added intermodulation and harmonic distortion inaudible. Added hum and noise below audible limits. Input/output dynamic linearity deviations inaudible. If there is more, someone please tell me what it is."
Peter: You have listed a bunch of easily-measureable characteristics.
Can you prove it's all-encompassing?Soundmind: If you can find the loophole in the mathematical analysis that defines the waveform analysis and transfer fucntions, then the list is incomplete. So far as I can tell, that all that's out there in the known universe. Note that this is not an answer to the proof question. Looks like a statement that static analysis is all there is to measure, doesn't it?
Peter: "For example: can you tell me how things like microphonics or triboelectric behavior are predicted from the LCR model or the static transfer function? Or do these things not exist in your universe?" CAN YOU PROVE THAT THERE IS NOTHING ELSE TO MEASURE? Just examples of things that are not covered within the static transfer function analysis
Soundmind: Declined to answer
I'm not sure how you arrive at the conclusion that we are saying the same thing.
I think we have exactly opposite world views:
Soundmind: I won't acknowledge its existence until I can measure it.
Peter: I can't rule out its relevance until I can measure it.
The only thing we agree on is the need to measure something. Hardly common ground.
Peter
