NOS will often roll off more than designs that upsample.
R-2R is inherently less linear overall and has differential non-linearities also as it is impossible to design precision resistors to the requisite degree of accuracy. Therefore you will get more correlated musically related distortion. This is a fact. This is why engineers prefer Delta Sigma for linearity.
Ultimate linearity is DSD or high resolution PCM through a delta sigma style DAC. The only issue with lower bit rates is higher noise. This is why the latest delta sigma designs are 6 bit - a hybrid between R-2R and a single bit delta-sigma which is achieved by massively parallel 1 bit delta sigma converters (equivalent to a resistor network that achieves bit depth through additionnof various resistors)
