Yes, of course. I just have a gut feel that the signal will hold on below the noise floor a bit farther with analog than it will with dithered digital. I really don't think it matters much in the real world as there are more important considerations in both formats. On the CD that gonk has, I created a whole bunch of stimuli including reverb tails that were originally 24 bit and reduced them to 16, 12 and 8 bits. It is absolutely amazing to hear the sound continue
through the noise floor (from the dither) and fade to inaudibility on the 8 bit examples. When dither is omitted, the sound gets
very, extremely ragged and then drops off suddenly to nothing.
