I’ve no doubt that some of these measurements don’t occur because there isn’t the education out there to really understand the data! Plus- heaven forbid- you know how something sounds by looking at the measurements!
If we reach a point where sound quality can be accurately predicted by measurement I’d have zero resistance or issue with it. My point is acknowledging we are not remotely close to doing that now.
Currently used measuring techniques seemingly can’t hold a candle compared to the extraordinary capabilities of the human ear-brain axis processing pathways (Thank you @mahgister ).
You can use cheap off the shelf Op-amps to allow any mass produced entry level DAC to measure quite well and yet sound utterly underwhelming (Like crap).
