One of the funny things about audio is that you only know that something (detail, resolution, imaging, etc) could be better, is when you actually hear it in your system, no matter how good that system was, in your experience, to begin with. Auditory memory is so short, and also imagining something better as an actual event is so difficult, that it makes it easy for the vast majority to live with whatever system they have without bothering about the need for an upgrade, We audionuts are blessed in some ways, but also cursed...
