My suggestion for the SINAD Wars/hyperSINADitis (that's gold btw) would be to leverage the work that
@flipflop has done on the
Audibility thresholds of amp and DAC measurements and add benchmarks to the SINAD histogram that is currently color-coded by quartile. The quartiles are arbitrary, and what I have seen happen is a new user asks for a DAC recommendation and someone suggests to pick any DAC in the blue range of the SINAD graph. Then another user will chime in that any DAC in the green and above is audibly transparent, and the debate about the SINAD level for audible transparency ensues. The chart also gives newbies the impression that higher SINAD is always better, and if they don't end up taking the time to dive a little bit deeper into the user experience that SINAD actually translates to, I think they draw a conclusion that most members of ASR would not want. I also think (and this is obviously debatable), that little SINAD histogram has influenced manufacturer's product development for DACs to top the chart with the higher SINAD, i.e. hyperSINADitis. Personally I would prefer manufacturers to compete on price and other features that very few budget DACs have like EQ and streaming capabilities, instead of spending time integrating the latest and greatest D/S chip.
My specific suggestion is to pick a SINAD threshold for audible transparency where the average listener will practically never experience any distortion, and color code DACs above that threshold green and DACs below that threshold as red. I manage an operational analytics team so I am hyper-sensitive to the design of visualizations because I understand the influence on the conclusions drawn and behavior changes they can have on end-users. You wouldn't believe the minutiae I get into about seemingly simple choices such as the color of an icon, but when standardizing scorecards across hundreds of people very small changes can have large downstream effects.
Your idea to write an article on the limits of stereo could help, but I think that will be preaching to the choir because the folks taking the time to thoroughly read through it are not the ones I'm concerned about.
