No, you are missing my point. In the same way as we do (or at least should do) when we develop software, we isolate the volatile parts from the stable ones. The loudspeakers have looked the same for decades. No revolutionary changes in amplifiers in a long time. The same with DACs. That means that when a software update bricks my adapter, or a new much better standard comes along, or I decide to leave the Apple ecosystem, I only need to replace one small part of my stereo system, not all of it.
