Most audiophiles are a mixture of love of music and of great sound. So, for most, the better the sound the wider the horizon of music accessible to be appreciated. I have known a couple of music lovers that would gain the same satisfaction from a horribly reproduced tune from small transistor radio or a high end system. And conversely some audiophiles that seem to completely lost any appreciation for music through the relentless pursuit of more detail and slam, constantly swapping equipment and quickly becoming bored with what they have.
So, like in all pursuits there are all kinds of people with different interests, motivations, and tastes.
My first reaction to a person having a system that makes music they would not ordinarily listen to compelling is to offer them congradulations on putting together an outstanding system. The true mark of success in building a great system is not being able to drag yourself away from it.
