Are you saying that you find noise an issue with 16-bit playback? Anyway, when you say "it takes 13 bits to get to 0.01%" what exactly do you mean? If you mean without dithering (ie theoretical) then yes - but fortunately this isn't what ever happens. This page explains it nicely. http://www.hifi-writer.com/he/dvdaudio/dither.htm In practice (which is all that matters) noise - or distortion if you prefer - is well below the 0.01%. In their example, the residual noise is ~30dB below a -60dB signal. This is why digital has (pretty much) killed off analogue in professional recording environments - analogue can't get anywhere near this performance. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
