Cello, the best test of hypothesis' is when the candidates do not know that they are under test and in the case of audiophiles, it is best to NOT use "sophisticated" listeners. Note that I said that the candidates are under test, not the device, for you are really testing if the candidates can hear a difference, since you are so sure that there is a difference . If the candidates had shown no difference in hearing the cds it is the candidates that failed the test, since your affirmation is that there is a difference.
See the problem here with using "sophisticated" listeners to validate your assertion?
Geoffkait, if you are one who thinks that the direction of a fuse in the AC mains line makes a difference to the sound in an amp, then of course you will think that cyroing electronics and cds will make a difference and probably you will hear a difference also.
