I’m sure it was unintentional but you misrepresented my position. I absolutely agree that different DACs sound different, and that the oft-cited measurements of DACs (e.g., by ASR) are woefully inadequate to accurately representing the complexity of the differences in sound. But the process involving streamers - right up to where a data stream is introduced to the DAC - strikes me as fundamentally different. There’s digital data, there’s jitter, and other sources of noise, and for these, there are rather straightforward measures. I base this on my review of a significant number of what I believe to be credible sources - engineers, designers, etc. - who are infinitely smarter than me on the topic.
I don’t think saying “everything matters” is a rigorous first principle. A/B comparisons are really, really hard; aural memory sucks; confirmation bias is real. I don’t fault people who think they hear differences where I doubt they exist. I believe they are earnest and well-meaning. We make these same mistakes in all walks of life - our views of people, politics, sports. But I’m a big believer in starting from a shared set of facts - truths if you will - and I see an opportunity for one here. So while our failure to come to agreement on this one isn’t a threat to democracy, I do thing it’s a lost opportunity.
So let’s just agree to disagree, and agree not to move towards tribalism. (Not saying you were, btw.) And thanks for your engagement with me, and more importantly, the op.
