(scratches head and makes puzzled expression) Erm Sean - the digital level control reduces SNR at the DAC output because the noise is fixed but the signal goes down - I know that and I don't think I've said otherwise? I'm agreeing with Mr O'S hypothesis. And I was trying to find the mythical "point of damage" caused by "lost bits"... I know the answer is no - I knew before I started - I'm just looking for some way of demonstrating it to others since some folks clearly believe otherwise! Listen to the fade-out on any CD made in the last 20 years. It was doubtless achieved by running an algotrithm in ProTools that works in exactly the same mathematical way (dither notwithstanding) as your SB control and I'm damned if I can hear a point in the fade when the music falls to bits... :) Still confused. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
