If cost was no factor, what system would you build as your main audio system?

I realize there are some, who frequent this forum, who already fall into that category, but for many of the rest of us, even though we are quite happy with the systems we’ve built, maybe our dream system, if financially possible, would be something other, or more, than what we now have. What components do you now have and (if finances and circumstances, within reason, was no factor) what components would you add or change, to build your dream system?
We all have individual tastes and likes in music and different ideas of what audio components would most satisfy those likes - so, without being critical of someone else, lets throw out some ideas....Jim
