I've recently come across some audio sites[0][1] that measure audio equipments performance and among other measurements, report their 'Signal-to-noise and distortion ratio (SINAD)'[2].
I applaud any efforts to quantify audio equipment and systems in a measurable and repeatable way. That said, do you think SINAD is a meaningful way to rank equipment? (understanding that it's only a measure of one measurable variable).
