In Reply to: I believe it is the tests that are flawed, not the equipment posted by E-Stat on November 13, 2002 at 14:47:59:
Which is why I disagree with rcrump about the validity of DBTs. You have to figure out how to corelate what we hear, with what we can measure if you are to get realiable repeatable results. DBT's are also important in dcided what is important to measure, and what isn't."Yessiree, we can measure tones right on down to the basement! For those individuals who enjoy listening to test tones, then the audible results would likely correlate with the measurements. Fine."
You also have to understand that the simpler a test the better(Good ol' worn out KISS). The trick coming up with the right surrogate test signal to achieve the desired results. It is quite possible to make a test signal so complex that a room full of Cray computers can't properly analyse it. So what good is that?

This is what we lay people call music , the reproduction of which is the raison d'etre for the high fidelity component. Easily quantifiable tests based on simple tones makes for easy test results but establishes useless proof. That is unless of course you spent your twenty grand on equipment for listening to test tones.
"That is unless of course you spent your twenty grand on equipment for listening to test tones."Well, that is what test equipment does best.However, music is a series of harmonically related tones. The difficulty that test equipment has with it is that it is random in it's nature.
Test equipment is great for evaluating test tones, not music. It can quantify meaningful differences only for those who choose to listen to test tones.For those of us who listen to "a series of harmonically related tones" , however, the results from the test gear does not yet correlate with audible results.
