What is your favorite line source speaker?

I am looking for reasonably priced line source speaker. By line source I mean something like the Epiphany. I want it all. Good imaging, transients, midrange, good bass and low level resolution. I am shying away from electrostatics. If you have had a good experience with such a speaker please share it with me. Under $20k please. I like tubes and vinyl. I live in apartment so I don't want it to take up all the space.
