Great example. In those competitions, participants would probably do *worse* given faster switches. On the contrary, in audio difference tests participants do *better* with faster switches. That's the point of research - sometimes it teaches you things. > > You obviously skipped my last couple of paragraphs - I don't rely on > A/B testing. I think there's some linguistic confusion here - I have no idea how one (I may have said 'you' before, but I'm American, and here you=one) would compare two things, let's call them A and B, other than by comparing them - that's what I call an A/B test. > > Let me summarise our positions: > > You maintain it is difficult/impossible to distinguish between digital > sources in a scientifically-valid DBT with shortish listening periods. > > I am saying that it is possible to hear things during extended > listening > that you would not pickup in a short DBT. > > You conclude that all/most digital sources are the same. > > I conclude that DBT testing is not an appropriate test in this > instance. > > Would you agree with this summary? > Agreement would be very boring :-). No, I don't agree. First, I think short-term tests are much *more* likely to reveal differences, based on the research I've mentioned above. Second, even if that isn't correct, what needs to change is the length of the test - NOT its DBT nature. A non-DBT test will never be meaningful, but a long term DBT (while possibly difficult to perform) might be. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=37553 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
