Nice topic, mapman!
For me, it is that my hodge podge of components, wires and speakers all work together synergistically to make music I love listening to, even when the source material is not up to audiophile standards. I have heard many systems, at shows, stores, and homes, and the only time I have any envy is on rare systems that cost multiples of what I have spent on mine over the years.
@hilde45... I have 6 foot ceilings in my man cave, and although it's hardly ideal, I have done only a little work on the room acoustics. I think my quasi omni speakers have helped in this regard. And since it's a super quiet basement, I can crank it without disturbing the rest of the house or the neighbors.
