And from what I read, at least, many of the AVRs with mediocre SINAD measurements, are using Chips and components that are decent quality.What makes these DACs so well engineered? I'd be curious if @amirm could put it into words or even an article. If you were looking at a teardown of something 120 db SINAD vs 100 (although not bad) or 80 or 60. It can't all be about the components on the board - we're talking a lot of cheapy DACs on here. What are these engineers doing to attain such measurements?
Is it just implementation and spurious noises that make their way INTO a component or chip, or is there something greater going on/.??
