Re: Re: I have the solution...

 

Let's revew.

You start this thread by mis-representing the work of Sean Olive and Floyd Toole in a way that you can stratify groups of listeners as a way of shoe-horning yourself into the group with better hearing (than those of us who claim no differences between cables). Oh, and the evidence that Olive/Toole provided to you was collected using proper DBT procedures.

After giving some credence to properly conducted tests, you then start back-peddling, and try to find evidence that all these tests are flawed. And your two articles come from Stereophile (presumably, conflict of interest is lost on you.)

One of these articles tries to build it's case on "type 2" statistical errors - which are known to everyone who has ever done a statistics course by the way!!! Stereophile gloss over the point that the probabiliity of making  "type 2" error can be made arbitrarily small by increasing the number of tests. However, Stereophile have for years been claiming the probabilty of correct detection is high ("differences are readily detectable") therefore the probability of making a type 2 error must be small even in small numbers of trails. They cannot have it both ways:

either the detection probaility is high and therefore DBT works.

Or the detection probabilty is low and therefore the differences are not worth the money!

Your opening gambit was based on the work of Toole. However, now you are reduced to mocking his name along with Lipshitz - which is something I would expect from a child.

As for there being "sufficient evidence" that DBT is flawed, well, you've been extra-ordinary selective in the information you've provided. If you'd looked at more of Floyd Toole's work, you would have found at least a dozen papers which are based on DBT's and have provided genuine repeatable results, and if you'd followed the references in those papers, you would have found hundreds of experiments using thousands of subjects all conducted using DBT.

If there is any "spin" on DBT it has come from Stereophile.

As for you not participating in a test, then I can only presume that your hearing ability is of the fleeting variety that only works when you can see what the result should be.

"Datty Boy" == "Batty Boy" == "Homosexual"

If you think implying that I'm gay is an insult, in this day and age, I suggest you need therapy. Or are you going to claim that that was not your intention as usual...
