ABX testing among members over the net

Can you?

For this specific case, I only was able to spend time with AB and select my preference, and am waiting for dekkersj to process more samples for others to listen for themselves. So the test has not ended yet. Please read through the previous threads. Feel free to download and listen to the samples yourself. The difference file indicates there is a difference. Some conditions may not allow the difference to be heard.

I just focus on getting a system good enough so that differences can be heard, and the system can continously be improved.

I assume you did an AB comparison. What was your ABX score?

I think you are trying to draw scientific conclusions. This is not the purpose of this thread. And the test is not even ended.

I already mentioned that I listened to the sound files. I'm fully aware that there may be conditions which may influence the outcome of a listening test. That's why ABX testing is so powerful, the strongest influences are effectively eliminated.

I try to focus on things that really make a difference. There are indications that people tend to overemphasize the relevance of coupling caps on sound quality.

This thread is about ABX testing, this thread is not about keeping science away from places where you don't want it to go.
Be aware that if you perform an ABX test on two supplied sound files the results may be scientifically relevant.

If you read the approach in the first post, it is obvious the purpose is to use the ABX method for each participant to see if their selections have a preference trend or not, and allow readers to see how different playback systems might effect the results. The intent is to just let people make thier own decisions based on whatever they can make of the information. No need to be upset if any individual cannot hear the difference. As a matter of fact, it's even a blessing that one can take things easy and just enjoy.


I'd be interested in seeing what others come up with after the sound tracK I posted is processed.

Please feel free to be the Conductor of a test. I would be willing to post additional music segments if necessary.

Did someone say Arnie Krueger??? I thought not...

problem as I see it is subjective arguments apply only to those making them, and are indeed valid for that person and others who agree with them. They are not valid as a generalization as to the "sound of the DUT, drug vs. placebo, etc.." applied to a population outside of those choosing to accept the results...aka general population of listeners, drug takers, etc. ABX is an attempt to set ground rules for making positive characterizations using standardized procedures that a given group agrees upon.

If you don't believe ABX works, then the results aren't valid for your set of preferences. The argument never ends, because people are arguing 2 different things.
