Dithering is entirely optional and affects what happens in the bottom half bit (I'm sure we've been over this before?). Basic electronics 101... What happens when you put a changing DC voltage into a capacitor?... Capacitor acts as an integrator... What comes out reflects the integral over time of what went in... -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
