<sigh> You're not hearing what I'm saying - you may not agree with it, but you're not acknowledging it. I hear what you're saying about test participants hearing differences with faster switches and don't entirely disagree, but I believe that some differences are not immediately obvious in short listening tests and only become apparent with extended listening. >> 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.

Point 1: see above Point 2: I didn't suggest that the extended listening should not be a DBT.
