You mix things...😊
Blackberry and Iphone it is phone MASS market : the same market...
Cd and streaming or ripping etc: it is MASS music files market : the same market...
Audiophiles are not defined by being MERELY in the mass market... These two are different targetting market...
For sure technology is evolving which IMPLIED some mid level convergence between mass market and audiophile market ... The mass market audio becoming more "audiophile" by the technological improvement progress and the audiophiles market becoming less costlier for the same reason... But these two market the mass market and the audiophile market will stay distinct for the decades to come... Why ?
Because music is not sound, and sound is not music ; even if they are not separable they are very distinctive...
Then one market does not replace the other they COEXIST for different goal and different reasons...
Then we are not all designed by our audio history and taste from the same "plaster mold"... We are all different and a solution for one is an impediment for another one...
I own no iphone... 😊
One market does not replace the others...
What about the Blackberry being relaced with the iPhone?
The CD being replaced by streaming?
