Actually it you that is completely missing the point. You believe that -144dB is not audible. You believe that the rounding error in a SB volume control is -144dBs. You believe in blind testing. Several people heard the effect of the rounding error in the SB3 volume control when it was changed. They heard this blind: they had no idea that anything had changed. Therefore at least one of you assumptions is wrong. If you are a real scientist you would be interested in giving the subject some though, and trying to ascertain where you are wrong, and you would be open minded about it. That's what science is about - it seeks to explain that which we observe. Even great minds (much greater than yours or mine) have been wrong. So is the effect of the error -really- -144dB, or can people actually hear a -144dB error in music? I'll leave you to think about it for yourself, but if you care to put up $1M I will be happy to accept your challenge and your money. -- Patrick Dixon www.at-tunes.co.uk ------------------------------------------------------------------------ Patrick Dixon's Profile: http://forums.slimdevices.com/member.php?userid=90 View this thread: http://forums.slimdevices.com/showthread.php?t=45736 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
