You have done marvellous things for the community, and you've been kind enough to make it open source. What more can one ask for? While I can certainly buy into the explanation that identical code base can end up being executed in a variety of different fashions depending on other more or less spurious configuration factors (I make my living by writing software, so I know that to be the fact), the math behind proving/disproving that such differences can make audible change is too intricate, and the paperwork is simply overwhelming. I am personally capable of hearing the differences between various versions, but I'm not gonna be a stickler about it. What I'm doing, and what I think all others who are hearing the differences could be doing, is hoarding various versions. That way, should it so happen that my SBT gets upgraded to some less desirable version, I could always go back and override it from one of the more desirable versions I've squirrelled away. That way, we won't be impeding your work (i.e. you should not be tying yourself into a knot trying to appease and placate the twitchy ones). ------------------------------------------------------------------------ magiccarpetride's Profile: http://forums.slimdevices.com/member.php?userid=37863 View this thread: http://forums.slimdevices.com/showthread.php?t=94855 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
