If, we want to listen to music in our home, and we are unable to bring in people to perform, then we require a system of some kind to be able to do that.
Some, don't give a flying what that is played on - iPhone speaker.
Some, care what that is played on and how it sounds. There is a secondary enjoyment, the beautiful tones, the timbre and contrast, the presence of the sound of the music.
Music only exists if there is sound. Why not have that sound be as pleasant to your ears as possible so as to maximize your enjoyment of the music.
Or perhaps the holier than thou lecturers of "Audiophiles listen to their system" BS spewers would be perfectly happy standing outside of Home Depot listening to their favourite artist coming out of the announcement speaker while they wait in line to get in...
It is possible, for those who are capable of parallel paths of enjoyment to be able to listen to the music as well as the sound quality of it as it's being presented.
If you are on this site, you are an audiophile. And if you're not, and you are posting on equipment threads, then you are either lying to yourself, or, you are in fact not an audiophile and are just trying to stir the pot.
