In Reply to: RE: "place no credence in ... uncontrolled tests" - fair enough. But why would you place any credence.... posted by Tony Lauck on July 02, 2015 at 18:24:27
10x? Where did that come from? Do you mean to say that the 180 mph speedometer in my car is no good above 18 mph?

This shows that you don't know anything about measurement systems.
I actually gave specific advice to him on what needed improving but he seems to insist on using the same stuff.
Waste of time.
That would be most interesting. Do you have any links to such a discussion?
So do you still think USB cables all sound the same?
I guess you might not understand the meaning of the resolution? Are you traveling 18mph or 17.999999?
I was being facetious, of course. And, resolution was not explicitly stated as an issue in Tony's post, to which I responded.
Now, here is a question for you. What is the difference between accuracy and precision? It seems to me that something can be very precise in the sense of having many decimal places in the answer, but it still might be wrong - off target.
Precision does not answer the accuracy question, and accuracy does not answer the precision question. Can an analog voltmeter with its swinging needle not be just as accurate in getting the magnitude right enough for purposes of comparison as a digital one with many decimal places? Aren't both speeds in your 18 mph example equally as accurate, with the many decimal places in the digital representation being useless for the purposes of driving the car?
I am completely open minded and just as ready as anyone else to jump on poor Archimago if indeed his measurements can be proven to be inaccurate. I am not seeing that proof, though. Do you have it? I am seeing a dismissive wave of the hand by many that seems motivated by a distaste for his results rather than the reason stated, which is his "bad" testing equipment and procedures.
I listen, too, and I do not make measurements, except for room acoustics, and I do reach my own conclusions. I do question those listening conclusions, especially if there is a perceived small difference, and try to avoid at least conscious bias. None of us can do much about eliminating unconscious bias in listening, except to try to design listening experiments or measurement protocols that reduce the possibility of unconscious bias, which is known to be pervasive in many fields from a host of experiments.
But, are anecdotal listening reports under uncontrolled conditions the gold standard? That is what many here seem to want to be the case. My own listening is often good enough for me, but I do not presume it to be good enough for anyone else unless I can offer more objective proof.
