The three main sources used are parity in creating an enjoyable recorded music. Neither supersedes the other in producing music to a standard capable of encouraging long-term listening.
Added to the equation is where one is invested in their choice for a used Source/sources, and shares their thoughts on the impact being made on them, as a result of their choices made.
Some are keeping to a single source, as a maintenance of a superseded technology, or have selected multiple options from a source to be used. Another has detached from use and ownership of superseded technologies and has invested in the most relevant technology.
The most relevant technology certainly takes up less real estate and is able to create music from a multitude of methodologies, extending beyond the home system, using devices pretty much ubiquitous to nearly all individuals, i.e., a phone + ear buds, and when in the home, with hardly any change to the methodology for using the phone. The same phone can be used with another auxiliary and reproduce the same music replays through $100K Speakers. Why would this not be promoted as a method to listen to replays of recorded music.
