The design of the circuit and the choice and combination of components round the DAC chip, last but not least is the digital transport (its role is as at least as crucial as a DAC) – all these factors can make a huge difference. Also in practice, there is so much more to it. What surrounds it is equally if not more important such as power supplies, I/V conversion stage, SPDIF receiver (if there is one) and an output stage. Having said that, let us also not forget that it is not just about a type of a DAC chip. Those who tried a decent digital filterless R2R design such as the popular NOS TDA1543, know its naturally musical sound character. In order to substantiate any claim, one needs to compare a typical sound of a DS DAC design with a well designed NOS (non- oversampling or digital filterless) R2R DAC design. ![]() The analogy would be to prove that all apples are better than pears. First of all, it makes little sense to prove what is better in theory because there infinte number of variables of implementation in designing and building a DAC. ![]() There is a never-ending debate on the topic of what is better: Delta Sigma (DS) or R2R (R/2R or resistor ladder) DAC designs. A reflection on digital to analogue conversion concepts based on theory and practice
