I don't think it's helpful criticising someone for not running proper DBTs of loudspeakers. As far as I know, only one or two members here have tried.

I know the loudspeaker comments were part of a longer post that had many other issues, but I don't think ABX-ing loudspeakers is a realistic thing to jump on.

The trouble with ABX testing is always the fact if you want it to be truly objective you have to collect a large enough number of subjective test results to start with, and then apply statistics in order to filter out the unwanted subjectiveness part. This is because every individual test result always has a significant chance of being highly inaccurate, so you need lots of people to participate if you want the final conclusions to be reliable ones.
Often, if not practically always, it is too time consuming and/or too uneconomical to conduct an ABX test properly, i.e. in such way that expectation bias doesn't creep in through the back door etcetera. Experts in auditory neuroscience and psychoacoustics have gathered experimental evidence which appears to indicate the following. Humans who remember different things are perfectly capable of hearing the same sounds differently as a result of remembering different things. For example, Bob Stuart of Meridian, who has a Ph.D in neuroscience, believes that it is perfectly possible for a person to not hear a specific detail in a piece of music when it is played back on one particular system "A", then to discover this specific detail by listening to the same music again on a better, more resolving system "B" next, and then, finally, to turn back to the previous system "A" and always hear this detail on system "A" even though the detail could previously not be heard on system "A". Moreover, Bob Stuart believes rapid switching between sounds can inevitably cause humans to perceive sound objects differently.

As a direct result from this, my brain now automatically fills in the missing detail where it previously couldn't. It previously could not, because the information required for that had previously not even been stored in my memory yet.

Cite the law that says people taking ABX tests are not allowed to practice beforehand in any fashion they choose (e.g.: sighted, blind, standing on their head worshipping the flying spaghetti monster).

I don't have to see what might be causing them to be able to remember that I heard them. So because I can remember them, I cannot always avoid being biased by them.

...and that's the point! If you can demonstrate your bias while blinded then congratulations, you passed.

I'm not THAT stupid.

Your continued (and lately childish) arguing from authority doesn't paint you as all that smart either.

I've had some public discussions with Julf in the past.

Do you want a medal? I doubt Wombat's post was intended solely for you. While you're the latest uneducated opponent of objective testing, this thread is not about you. In fact, it isn't even about the debate you are trying to have (albeit incompetently). (EDIT: Thanks to the thread split this thread can be about your religious argument and all it's fallacies. biggrin.gif)
