Doing a double blind test with statistics is quite difficult with audio gear. The double protion of the title is that the presenter also doesn't know which stimulus is being given to the subject (non-verbal clues are not allowed). However, it's much easier with water. After buying bottled water for years, my wife suggested that I subject myself to a double blind test with three different types of bottled water and a fourth choice, tap water. I was confident that I could tell the difference between each of the four choices and that I would have no dificulty identifying my favorite. The results were statistically significant (overwhelmingly so) with my clear choice in the experiment being the tap water (not my 'favorite'). -- Now, having said that, I don't mean to suggest that I or anyone else would have similar results for high end audio. I personally believe that the system I have today, that I very much enjoy, is a direct result of successive improvements made by subjective comparison of alternatives. I only mention it to indicate that the results one gets from such tests can be surprizing and that you too can give it a try with other subjective choices that are easier to conduct as a double blind test.
Have You Ever Put Your Golden Ears to the Test??
First let me say that I'm not one of the naysayers that Twl refers to in his thread about "Sonic Relativism", so please no attacks. I have no agenda.
I'm just curious if any of you have (or would be willing to) put your ears to the test in the way of a blind comparison. If so, what were the results? It can be quite rewarding to know that you can discern differences between things such as cables, DACs, etc.
I was at a good friend's house this weekend and we decided to do some blind comparisons of CD vs. SACD. We had three discs of various types of music (Friday Night in San Francisco, Keb' Mo and Harry Connick Jr.). I sat in the sweet spot and my friend switched discs playing one cut from each disc CD/SACD at random.
I could discern the CD from the SACD every time, but I have to say that the differences were more subtle than I expected. Of course, I'm no scientist so my methods may be open for scrutiny. I'm just curious how many of you try similar tests?
I always find it interesting when people say that they "heard" a cd player (or other component) and it was really great or really crappy or not very exciting. This almost always refers to having heard it at a dealer. How do they know they didn't "hear" the other components? What's the point of reference? The only way to really listen to components or accessories is within the confines of a "reference" system. For most of us that simply means our own system. And even then, the only way to confirm that we're hearing what we "think" we're hearing is to do some sort of blind test.
So...How many of you have put your ears to the test? If you haven't...Would you? If not...Why not?
