Interesting stuff, Leslie: I didn¹t know that people tended to retain their really high frequency hearing even if they lost their high mid sensitivity. I guess it makes sense, since we are not being bombarded in that range the way we are with the more audible frequencies. As far as ³feeling² the difference at 192k ­ if you say you do, that¹s fine. I had suggested to the OP that he try different sampling rates, and he came back and said he didn¹t hear a difference. In his case, given the fact that he is running out of tracks at 192k, I really think he should be using a lower sampling rate. I¹m the first to admit that I haven¹t done any kind of listening at 192k (yet) so I can¹t say for sure if I would hear a difference. My hunch is that I won¹t, but we¹ll see.... However, I think we always need to be aware of the power of suggestion. Not dismissing your claims at all, but many people, when they do an A/B test expect to hear a certain difference, so that¹s what they hear. I¹ve certainly noticed that with microphone ³shootouts² etc. - when people don¹t know what it is they are listening they become much less sure of their preferences. It really should be a double blind test, where nobody knows which track they are listening to until the end. If there is a clear difference that is heard every time, then I think we have something pretty concrete. Blair -- blairfisher@shaw.ca
