Axiom Home Page Forums General Discussion The Water Cooler All DACs not equal

As you said, it may not be the DAC, but the pre-amp stage which comes after it. Too, the implementation of the DAC could be at fault, along with the relative age of the components. It's the recent Delta-Sigma DACs which are all basically equal to each other. Comparing any one of those to and older MASH, or 16-bit 40x Oversampling, will have differing results.
