hi,
there is a simple, unqualified improvement due to the fact that signal adds linearly and quantization noise adds with a square root. in a 4x system you have 4 times the amount of samples in a given time period as compared to a 1x system.
the effect is not limited to a dithered system. however, it seems that a dithered system also benefits.
it seems to me that the average of the 4 quantization levels in the 4x system is more accurate than the corresponding 1 quantization level in the 1x system. this is of course true without dither.
right.
