I don't just believe it, I presented an argument proving it. The argument could be wrong - maybe I made a mistake, maybe I assumed something invalid - but if so, please show me where. Note that my analysis is fully consistent with about a century of controlled experiment. > You believe that the rounding error in a SB volume control is -144dBs. If you're talking about the error introduced by the firmware change, no, I don't believe that. I don't know what was in that firmware, so I don't believe anything about it. I do believe that rounding errors should only affect the last bit - that's just basic arithmetic - but that doesn't mean someone can't make a mistake in the SB firmware. > You believe in blind testing. As does 20th and 21st century science and everyone in the world except for a few crackpot audiophiles, yes. > Several people heard the effect of the rounding error in the SB3 volume > control when it was changed.

Now, maybe the one you're talking about was real, and maybe it wasn't, but it's not exactly strong evidence stacked up against the laws of physics and an entire field of science, is it, Patrick? > Therefore at least one of your assumptions is wrong.

You're one with the closed mind, Patrick. It's impossible for you to admit that your mind can ever play perceptual tricks on you. > So is the effect of the error -really- -144dB, or can people actually > hear a -144dB error in music? Like I said, if you're talking about the error in the firmware, I don't know, because I don't know (and can't possibly know) what it was, nor did I ever say I did. If you're talking about rounding errors in 24 bit binary numbers, yes, those are -144dB down. And you agreed with that a few posts back. Changed your mind already? I notice you haven't responded substantively even once. You've never challenged anything specific in my analysis, just made vague assertions and did your best to sow audio FUD. Why don't you tell us why you think 24-bit rounding errors aren't 144db down? Or why an effect at -144db can be audible? -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=45736 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
