Kal, thanks alot. We will also include a pink noise track in subsequent tests as another data point.
What would you say about a test that only used pink noise for every trial? Would removing musical progam material from an ABX test and just using test tones make the results more or less accurate? Does using music in the trials add too many variables to the test, if all you are trying to prove is if you can pick out one unit from another blind?
I found it difficult to use music tracks where things I was listening for maybe were 30 or 40 seconds into the track... Then, rewinding to the beginning, and waiting another 30-40 seconds, then rewinding again. That made it very hard to compare A, B, and X in my mind with such seperation in between...
However, when we did instantaneous switching between A and B, we all agreed we could hear differences. Why did an ABX test not be able to show the same results? I would be very curious to see if using a continuous signal - like a pink noise test tone - would change the results of the test, since it may be easier to compare the tonality difference between DUTs using pink noise...
