Hi
 I agree, the 1 bit converters are mostly better
than the 14/16 bitters because timing is much easier to
control than level. There are noise issues at the
high end but it is usually less than that caused
by response in the straight D/A's.
 As for the averaging filtering, I once thought it would
be best like Philip Belben suggest until I saw the FFT
results of some pure tones feed thru such a filter.
I think that zero padding is the only way to deal
with oversampling with a good filter following it.
IMHO
