XY (0cm) = 195.9 SRA
According to Sengpiel, XY should be "wider". But XY is demonstrably narrower than NOS BY FAR because it lacks time-of-arrival difference. And every cm reduction from 30cm makes the image narrower, but the SRA increases.
Trust your ears, not the charts.
Thanks for the reply. And maybe this is part of my confusion about these charts.
If you look at the localization of the source as presented by its position between the speakers, my interpretation would be that NOS yields a wider perceived image by the listener than would X/Y (given the assumed location of the speakers).
In other words, a smaller SRA will yield a wider stereo image. At least that is the way I interpret the charts.
I think Micheal Williams approach ("The Stereophonic Zoom") might be better because (I think) I read that he based his calculations on actual listening experiments. But the two approaches sometimes (often?) yield different results. Hence my curiosity.
Yes, listening and trusting your ears is better, but in my end of the world, there often is no time for doing any serious moving around of things, once they are first setup. Then, experience and intuition must take over. I am hoping that if I can gain an understand these two approaches (and their respective charts), it might help me in those situation where my experience and intuition are, shall we say, not what they should be.
