It’s market driven. Who cared about capacitors 20 or 30 years ago. People like us who tweek and upgrade electronics have found that capacitors make a difference in sound quality. Like changing tubes and interconnects.
Engineers who designed professional gear 40 and 50 years ago cared. Back then I knew some then 'old timers' who were aware. Can't comment on earlier, but no doubt some were aware.
I had a tube 'guru' tweak my Citation II with better resistors, caps & wire. Same cct & old tubes, but OMG.
