I agree, however, on the case of the R2Rs, I think it has more to do with poor transient resolution, most R2Rs are just trying to use resistor ladders to reproduce the digital signal, as the voltage gets smaller and smaller from the most significant bit to the least significant bit there are a ton of issues as the resistors can never match. Then there is the case that the sampled data just cannot be reproduced with transient accuracy, the digital signal looks like a ladder instead of a wave, that is where oversampling done properly takes things to the next level, because you add buffer points between the samples smoothing out the signal and having more accuracy in terms of predicting there the timing of the transients are, not too late, or too early. You can argue that an R2R DAC's strength is that it doesn't have a noise shaper, but all the other issues are crazy. The reason they sound "soft' and "warm" is because they have poor timing and transient accuracy, that's my take. I just cannot stand those DACs, but, I don't go to their forums to talk nonsense about those DACs to people that love their sound, I don't understand the need some people have to do that and then talk about other DACs instead
